Danmachi, Ch 126-130

Chapter 126 — Testing the Dying Will Flame

After finishing the day's work, Tsuna returned to his room.

He drew the curtains closed, switched on the magic-stone lamp, and let the soft amber light fill the space. The dim glow made it easier to unwind and think.

“The situation’s almost exactly how I imagined it would be.”

His reflection in the glass flickered as he spoke quietly to himself.

“My power really has helped push the Familia forward. Even those who’d been stuck in place finally found release from that pressure. Their talents and potential are surfacing through their own effort.”

“In just a month, the teams that used to stagnate have earned the right to advance.”

“At this rate, the Familia’s minimum level will keep rising—eventually hitting an average of Level 3, maybe even Level 4.”

“And once we reach that point… we’ll be able to stand on equal footing with the Freya Familia.”

He leaned back in his chair. Everything was progressing as he’d predicted.

“After the first Level Up, everyone pushing from Level 2 to Level 3 will work even harder to build up their Status.”

They’d lacked the harsh conditions needed for growth before—without challenge, there was no progress.

Now that he’d created that harshness for them, advancement came naturally.

“After that initial shock, once they realize they really can Level Up, they’ll start thinking about their next goal.”

“When they see how training in that kind of environment can make up for limits in talent or potential, more of them will start striving to perfect their Status.”

“Finn and the others won’t be exceptions either.”

“They didn’t push before because they lacked the means. But now, not pushing would be wasting the opportunity.”

“For a long while from now, they’ll be charting their own paths from Level 2 onward.”

That was Tsuna’s prediction for most of the newly promoted adventurers.

Self-management.

Once the initial excitement of leveling up faded, every adventurer would start planning their own path forward.

Of course, some would still focus only on raising their level—but when their Excellia wasn’t enough to progress further, even those people would cool off and start thinking more seriously about their future.

It was a natural development.

And Tsuna was no exception.

Still, his own preparations weren’t limited to raising his Status. Having experienced what Level 1 growth felt like, he knew that from here on, he didn’t need to burn himself out to keep improving. Steady, consistent progress would do.

His focus now was mastering the power of Annihilation Maker—refining his creations, stabilizing them, and expanding what that ability could truly do.

And beyond that… exploring his own inner power.

The Dying Will Flame.

In his original world, it had been the very root of strength itself.

Those who couldn’t ignite it naturally could still awaken their flames through sheer resolve, using external catalysts as a spark.

Tsuna extended his hand, imagining it—

and fourteen ornate rings appeared atop his desk.

Each bore a unique design: engraved family crests, gemstones of different hues, and the unmistakable insignia of the Vongola—seven rings representing the Sky Flames, alongside the Mare Rings, each with twin wings extending from the sides.

He picked up two of them—the pair that symbolized the Sky.

The moment his fingers brushed the metal, both rings flared to life, blazing with orange-gold light.

“Hm. Not bad. The purity of the Dying Will Flame’s increased—it channels the power much more smoothly now.”

He turned his wrist, watching the flickering glow dance across his skin.

“But for me, it’s not particularly useful anymore.”

Ever since his Dying Will Flame had evolved into “magic,” Tsuna’s flames were already at their purest state.

He could summon and control them anytime, anywhere—no rings required.

It was likely a benefit tied to having the Dying Will Flame as one of his Development Abilities.

For Tsuna, it was never about gradual growth. Either he couldn’t use something at all… or he started right at the pinnacle.

He’d gained the most refined version of the Dying Will Flame outright.

Because of that, the rings no longer held any real purpose for him.

“I wonder, though…” he murmured, turning one of the rings between his fingers. “Would these work on people from this world? Could they awaken their own Dying Will Flames?”

He smirked. “Guess I’ll have to test that.”

The first candidates that came to mind were Tiona and Tione.

He was closest with them, and their personalities made them the easiest to approach for help.

Besides, they both had strong, distinct traits—perfect for an experiment like this.

Tiona, all smiles and energy, bright and carefree, strong as hell and able to trigger damage boosts when hurt—she fit the "Sun" flame attribute perfectly.

Tione, on the other hand, had a fiery temper under her composed exterior—also strong, but with a sharper, more explosive fighting style. That aligned well with “Storm” or “Sun.”

Since the rings amplified the flame’s resonance through personal resolve, all they really needed was… conviction.

And adventurers, more than anyone, thrived on that.

If the sisters succeeded, it’d prove that the Dying Will Flame wasn’t limited to his world alone.

If they failed, he’d just analyze what went wrong and use Annihilation Maker to correct it.

That Sacred Gear gave him all the freedom he needed to experiment.

“Yeah,” he decided, leaning back. “Tomorrow, I’ll talk to Tiona and Tione about testing it.”

The twins had already perfected their Status and hit the upper limits of their agility and dexterity. They'd been holed up in the Training Space for weeks now.

With Loki enforcing a rest period for them, they’d finally have some downtime.

Perfect timing.

“Next,” Tsuna mused, “I should work on developing weapons that’ll actually help me.”

He glanced at his reflection again, eyes narrowing slightly.

“I can’t keep hiding in the shadows forever. If someone drags me out into the open before I’m ready, that’s going to be a problem.”

“I need equipment that can cover the gap I’m in right now—something to fill that vacuum until I’m at full strength.”

He didn’t have to think long to find inspiration.

The Red Dragon and the White Dragon—two sides of the same coin.

One doubled strength every ten seconds.

The other halved the enemy’s power every ten.

Boosted Gear and Divine Dividing.

Enhancement and reduction—offense and control.

Not to mention, they could grant the power of flight.

“They really are useful…” Tsuna murmured, a faint grin tugging at his lips. “Crossing the vacuum between worlds… even in the dark, they’d make excellent tools.”

He reached for his notebook, already sketching ideas.

“The Boosted Gear… and the Divine Dividing.”

“Yeah. It’s time I started developing my own versions of those.”

Chapter 127 – A Rare Morning to Sleep In

Tsuna stared at the crimson gauntlet covering his left hand.

“The basic functions are operating just fine. Once it reaches a certain threshold, it can transfer and evolve on its own.”

He exhaled slowly. “Next step… Balance Breaker.”

“Balance—Break!”

A low hum pulsed from within the red armor. The golden spikes that had sprouted from the gauntlet vanished, and a surge of energy spread outward, enveloping his whole body in a crimson blaze.

A full-body suit of red armor formed around him, every inch radiating explosive power—but he could already feel the time limit ticking down.

“...That’s even stronger than I expected.”

Only while wrapped in that state could Tsuna truly grasp just how overwhelming the surge was.

It wasn’t a simple stat boost. It was a total overhaul—strength, speed, endurance—everything was pushed to the limit.

His base physical power skyrocketed to the peak of what his current body could withstand, right up against the edge of collapse.

“So this is what the Balance Breaker of the Red Dragon Emperor and the White Dragon Emperor really represents… pushing one’s own ability past its natural limits. That reckless, unnatural explosion of power—that’s the essence of a Balance Breaker.”

He clenched his armored fist, feeling the energy roaring through every fiber of his being.

“The rise in baseline ability also raises the upper limit of energy tolerance. That means I can handle the output without my body breaking down.”

“This brutal, straightforward surge of strength is just the surface. What makes the Red Dragon Emperor and White Dragon Emperor so terrifying is how completely they can draw out that potential.”

“For example—removing the ten-second limit on doubling power. Instead of a steady rhythm of increase, it’s full release—no ten-second wait. The only restriction is what the body can take before it breaks.”

“That’s probably why Balance Breakers always have strict time limits.”

“And why the White Dragon Emperor of legend was known as the strongest of his generation…”

“Simply because his tolerance for energy was beyond human. His body itself was an exceptional vessel.”

Tsuna slowly deactivated the Balance Breaker. The red armor peeled away into light, leaving him in his normal form. He took a few breaths, testing his condition.

“Hmm… no damage. I can handle it just fine.”

“Looks like I was right. As long as the Balance Breaker’s output stays within what my body can bear, the duration scales directly with my endurance.”

“As long as I don’t cross that line, I can keep it active for as long as possible.”

“But once the intensity of battle exceeds that threshold… the maximum I can maintain it is thirty minutes.”

“After that, it’ll automatically shut down to prevent total collapse.”

“I’ll need to test exactly how long I can maintain it in combat—and find out where my real limit lies.”

And there was only one way to do that—through battle.

Of course, testing something like that alone would be dangerous. If he lost control, returning afterward would be… problematic, to say the least.

Letting the tension fade, Tsuna went to the washroom, splashed some cold water on his face, and stepped out of his room.

The sky outside was just beginning to lighten, yet the Familia house was already full of noise.

Footsteps echoed especially loudly from the third floor.

“Looks like it’s going to stay like this for the next six months,” he muttered helplessly.

As the one who’d sparked all this chaos, Tsuna couldn’t help feeling a bit guilty.

Following the noise, he arrived at Tione and Tiona’s door.

Knock, knock, knock!

Footsteps shuffled inside. When the door opened, Tione appeared—hair messy, eyes a little wild, clearly not at her best.

“Morning, Tione.”

The fierceness in her gaze faded instantly when she saw him, replaced by a flustered softness that she quickly tried to hide.

“Morning, Tsuna.”

“You’re up early today?”

He tilted his head. “Actually, this is my usual time. You two are the ones running late.”

He leaned a little closer, noticing the faint circles under her eyes. “Didn’t sleep well last night?”

Normally, when Tsuna came by, the twins were already up and alert. Today was… unusual.

He didn’t glance into the room, but the steady sound of slow, even breathing from inside was proof enough that Tiona was still asleep.

“Yeah… didn’t rest too well.”

Tione rubbed at her eyes with a weary sigh.

“It’s all Loki’s fault. She went on forever last night about the rules for using the Challenge Space. Tiona got all hyped up and dragged me back there to ‘try it out.’”

“Oh?” Tsuna arched an eyebrow. “That place doesn’t even have that many monsters in it yet. Just a few of those sluggish black Goliaths, right?”

“Exactly. Those damn black Goliaths.” Tione groaned. “Tiona insisted we go another round with one of them.”

Just remembering it made her jaw tighten.

“That thing was ridiculous! Its body was harder than reinforced steel—our attacks barely scratched it unless we hit with full weapon power. And even then, it healed almost instantly! We’d deal some real damage, and before I could even blink, it was good as new.”

“From start to finish, it stayed at peak condition. By the end, Tiona and I were completely wiped.”

Tione was practically grinding her teeth in frustration.

Undying monsters really were the worst kind—more aggravating than anything that could simply overpower them.

Tsuna gave a knowing nod. “That kind of monster’s not easy to deal with.”

“Hyper regeneration is its main flaw in the system. The Dungeon spawns creatures like that not for adventurers to conquer easily, but to crush them—to remind them what real danger feels like.”

“The reason you and Tiona struggled is because your destructive power couldn’t fully break through its defenses.”

“That massive frame, that thick hide—they’re both designed to nullify brute force.”

“When your strength gets dispersed across such a wide surface, the impact drops sharply. Unless you hit its vital point in one blow, killing a Goliath like that won’t be easy.”

Chapter 128 – “Sun” and “Storm”

The black Goliath’s power was undoubtedly that of a Level 5. Coupled with its absurd regenerative ability, even adventurers of the same rank would find it a nightmare to deal with—let alone Tiona and Tione, who were still a level below.

Despite its towering, building-sized frame, the monster wasn’t slow in the slightest. Its attacks came with terrifying speed, each strike carrying crushing force.

That thick, black hide covering its body resisted both physical and magical damage. Even first-tier weapons could only partially penetrate or get deflected outright.

But the worst part was its regeneration—so extreme it bordered on cheating. Unless its central Magic Stone was directly destroyed, every other wound would heal in seconds.

That meant unless you had the raw power to shatter the Magic Stone hidden inside its body, you had to first find a way to expose it. Otherwise, no matter how long you fought, you’d never bring the beast down.

“I know,” Tione sighed, exasperated. “But Tiona said, ‘If we can beat the black Goliath in another way, doesn’t that mean we’ve gotten even stronger?’”

“I’ll admit it—I got caught up in her logic. So I agreed to go fight the thing head-on in the Challenge Space.”

“The result? Its attacks were mostly neutralized by the Holy Shroud, but our strikes barely made a dent. Even when we managed to hurt it, the damn thing healed right away.”

“We tried every tactic we could think of, but nothing worked. We just couldn’t kill it.”

Just recalling the experience made Tione’s scalp prickle.

If they’d run into that monster in the actual Dungeon, their only option would’ve been to flee.

They simply didn’t have the strength to land a killing blow on something like that.

After an entire day of punishment, her body and mind had hit their limit. No wonder she’d slept terribly last night.

But that wasn’t what annoyed her most.

After all, Tiona had been the one who suggested the fight. And since Tione had agreed, she couldn’t really blame her sister for it.

She turned and looked at Tiona, still fast asleep, her breathing slow and peaceful. The corner of Tione’s mouth twitched.

“She’s the one who came up with the idea to fight that damn Goliath… and now she’s sleeping like a baby.”

“Meanwhile, I’m the one lying awake, fuming about it all night.”

So that’s the real reason you didn’t sleep, huh?

Tsuna couldn’t help but smile as understanding dawned.

It wasn’t just about being tired—Tione was irritated that the troublemaker who’d dragged her into that fight was still snoozing away without a care.

Knowing that, Tsuna found it hard not to laugh, even as he looked at Tione’s grumpy, worn-out face.

“Tione. Look down for a second.”

“Huh?” She blinked in confusion but obeyed, tilting her head forward.

Tsuna lifted his hand, his fingertip burning with a soft golden flame, and pressed it lightly to her forehead.

The Dying Will Flame flowed into her body, spreading warmth through her limbs. It was the power of Activation—stimulating the body, restoring vitality, melting away exhaustion and pain.

In seconds, the fatigue that had weighed her down all morning was gone. Her soreness faded, and her mind cleared as if she’d just woken from the best sleep of her life.

Tione’s eyes widened. “Tsuna, what was that? Magic?”

“You could call it a kind of magic,” he said with a small smile. “It’s a power I fully unlocked after I reached Level 2.”

“And actually, that power’s the reason I came to see you and Tiona today.”

That caught her off guard. “Huh? What does that have to do with us?”

“That’s what I want to find out,” Tsuna replied. “If my theory’s right, you and Tiona might be able to use this kind of power too. I wanted to talk to you about it—and maybe run a little test.”

“I see.” Tione’s eyes lit up. “Then come in.”

Before Tsuna could react, she grabbed his hand and pulled him into the room. Her amazon strength made resistance pointless.

He stumbled inside, glancing around just in time to see Tiona fast asleep on the bed, tangled in her blanket, hair spilling everywhere.

Always cheerful, always carefree... even when she’s being reckless, Tsuna thought with a faint smile, pulling his gaze back to Tione.

Her eyes were sparkling now, brimming with curiosity. “So, what do I have to do?”

“It’s nothing complicated,” Tsuna said. “This power isn’t unique to me. It’s a kind of energy that exists in everyone—it’s just that some people can control it naturally, and others can’t.”

“To put it simply…”

He spread his hand, revealing seven rings laid neatly across his fingers.

“Tione, put these on first. We’ll figure out which type of energy resonates with you.”

“Alright.”

She took the seven rings and slid them onto her fingers, one by one.

“What now?”

“Give me your hands. I’ll handle the rest.”

Tione hesitated briefly, then placed her hands in his.

Tsuna closed his eyes and focused, channeling a faint trace of Dying Will Flame into her body—just enough to stir what was already inside her.

The reaction came almost immediately.

A vivid red and a brilliant gold light flared to life on two of the rings. The others stayed dark.

Just as I thought. Storm and Sun—the perfect match for her.

Tione stared at the glowing rings, eyes wide in awe. She could feel something stirring deep within her—a new kind of strength, alive and burning.

“This is the Dying Will Flame,” Tsuna said softly. “The destructive nature of the Storm… and the life-giving power of the Sun. Two flames that couldn’t suit you better.”

Chapter 129 – Tione’s Wake-Up Call

“The Storm represents the power of Disintegration, while the Sun embodies Activation.”

“Some things you’ll only understand once you feel them for yourself.”

“Tione, hold out your hand. It’s going to sting a little.”

How bad could it be?

As an adventurer, Tione had experienced more than her share of pain. She doubted anything Tsuna could do would hurt that much.

Then the pain hit. Sharp and sudden. It tore through her palm, far worse than any claw strike she’d taken from a black Goliath or an Asterius.

She glanced down and saw a thin red cut across her palm, a line of blood burning with a crimson flame.

The fire wasn’t hot, but it clung to her skin like venom, searing deep into her nerves.

“Ah—ow!”

It was only a small wound, barely a scratch, yet the pain made her wince and grit her teeth.

“Why does it hurt this much?” she asked, staring at him in confusion.

Tsuna’s expression was calm. “That’s one of the Dying Will Flame’s properties—Disintegration.”

As he spoke, he brushed a finger across her palm. The red flame vanished, replaced by a warm golden glow.

This time, there was no pain. Instead, a soothing warmth spread through her hand, and she watched in awe as the wound began to close.

“That’s the other property you have—Activation.”

“Disintegration is simple to understand. It amplifies the damage you deal, and it prevents wounds from healing easily. You just experienced that firsthand.”

“The other, Activation, is its opposite. The flame stimulates your cells, accelerating regeneration. It doesn’t just heal injuries—it strengthens your muscles and body tissue, letting you draw out more power for a short time.”

“Disintegration… and Activation…”

Tsuna’s explanation was clear enough that Tione immediately grasped what he meant. Both abilities would drastically enhance her fighting capability—one increasing offense, the other extending endurance.

A grin tugged at her lips. “You’re saying I can actually use this power?”

Tsuna nodded slightly, turning her hand over and gesturing toward the two rings still burning on her fingers.

“Those two flames answer that question for you. As long as the rings resonate, it means you possess both Sun and Storm wavelengths. With the rings as catalysts, you can draw that power out.”

“It’ll take some practice to control, but with time, you’ll master it completely.”

He paused thoughtfully. “The only thing I don’t know yet is whether this flame will register as your ‘magic.’”

Tione’s eyes widened in surprise. “Wait—this could become my magic?”

“My own did,” Tsuna admitted. “But since I’m passing this power to someone else for the first time, I’m not sure if it’ll manifest as magic for you. We’ll have to wait for Miss Loki to update your Status to find out.”

“Right… that makes sense.”

Tione took a deep breath, trying to calm her excitement. If this really could become her magic, it would be a huge advantage. But even if it didn’t, she was determined to master it regardless.

“You just came out of the Challenge Space,” Tsuna reminded her. “You’re not planning to go right back in, are you?”

At that, her expression twisted. Memories of yesterday’s beating by the black Goliath flashed through her mind. Just thinking about it made her temples throb.

“Ugh, no thanks,” she groaned. “I’ll wait a week. Once I’ve got these two flames under control, then I’ll go back and beat that thing properly.”

A week to train and familiarize herself with the Dying Will Flames—that sounded perfect. She’d also need to talk to Loki and get her Status updated soon. If these flames did count as magic, the boost would be enormous.

Her thoughts circled back to Tsuna, and she looked at him a little sheepishly. “Tsuna… could I trouble you to help me train this week?”

“Of course.”

“Thanks! Then I’m counting on you!”

Her relief turned into a bright smile as she grabbed his hand—then froze, realizing what she’d just done. She didn’t let go, though.

Tsuna didn’t seem to notice; he was still a thirteen-year-old boy, blissfully unaware of the flustered amazon holding his hand.

“Tione,” he said after a moment, “since you’re planning to train seriously this week, that means Tiona’s joining in too.”

After all, he hadn’t come here just for one twin.

Tione followed his gaze toward the bed. Tiona was sprawled across it, sound asleep in a ridiculous position, snoring softly.

A vein popped on Tione’s forehead. She took a deep breath, forcing a smile in front of Tsuna. “Tsuna, turn around for a second. I need to wake her up.”

“Oh, sure.”

He obediently turned his back.

The moment he did, Tione’s gentle smile vanished. She cracked her knuckles, glared at her still-sleeping sister, and stomped over to the bed.

“Time to get up!!!”

THUD!

Her fist came down like a meteor.

The blow landed square on Tiona’s head, snapping her awake instantly—with a groan and a splitting headache as a side effect.

“Tione! What the hell?!”

“You’re awake now, idiot!” Tione barked, hands on her hips. “You dragged me into the Challenge Space yesterday and got me beaten half to death, and you’re still sleeping this soundly?!”

Tiona wilted under her sister’s fury, the fight draining right out of her.

“Now get dressed,” Tione continued. “Tsuna’s already here.”

“Eh? Wait—what!?”

Tiona turned her head—and froze when she saw Tsuna standing in the room, his back politely facing her.

Her face went bright red. She yanked the blanket up to her shoulders, clutching it tight as embarrassment bloomed from deep inside.

Tione caught the whole thing.

She glanced at Tsuna, then at her blushing sister, and a knowing smirk crept onto her face.

Oh, I see how it is.

Delight flickered in her eyes.

Chapter 130 – Come With Me

“Whoa—”

Tiona’s eyes went wide as the ring on her hand suddenly flared to life, two flames of completely different colors dancing above it.

“Tione, look! It’s really burning!”

Tione sighed and raised her own hand, where two rings gleamed with the same crimson and golden flames.

“I actually lit mine first,” she said. “And it looks like ours burn with the exact same colors.”

“Huh?”

Tiona leaned closer, her sharp eyes quickly spotting the truth—Tione’s rings were identical to hers, down to the smallest detail.

Tsuna smiled faintly. “Guess it really proves you two are sisters. Even the type of flames you produce are identical.”

He honestly hadn’t expected Tiona to ignite the Dying Will Flame of the Storm too. He’d assumed her aptitude would align with the Sun Flame alone—but apparently, both sisters were exceptions.

The Amazon twins shared far more than appearances; their hidden potential ran deep in the same direction.

“The red flame is called the Storm,” Tsuna explained, “and the gold one is the Sun.”

“The Storm’s characteristic is Disintegration. The Sun’s is Activation.”

Halfway through his explanation, he noticed Tiona’s expression had gone oddly blank—like a college student zoning out in a lecture. He sighed, reached out, and gave her cheek a playful pinch.

“Focus, Tiona.”

“Alright, let me put it in simpler words so you can keep up.”

“The Storm Flame boosts your offensive power. It makes your attacks sharper—strong enough to tear through an enemy’s defense or body with ease.”

“The Sun Flame enhances your physical ability—your reflexes, strength, stamina. It can even accelerate healing during battle, letting you fight longer without collapsing.”

Tiona’s eyes cleared as understanding dawned.

“Oh, I think I get it now,” she said. “Storm’s for offense, Sun’s for boosting myself.”

“In other words, both are for fighting. Makes sense, right?”

Tsuna chuckled. Her logic wasn’t wrong, and for her, that level of understanding was already impressive. She reminded him of a college classmate he once had—someone whose eyes were always a little too clear for their own good.

He patted her on the head.

“Yeah, that’s about right. Just remember—the Storm Flame’s extremely destructive. Don’t ever use it on anyone from your Familia. It’s dangerous.”

“Who’d even attack their own allies?” Tiona grumbled, but she didn’t move away from his hand.

Watching them, Tione cleared her throat pointedly.

“Tsuna,” she cut in, “you mentioned you’d be training us this week. How exactly are we doing that?”

Tsuna withdrew his hand and nodded. “Technically, igniting the Dying Will Flame was the first stage of training. Most people struggle just to trigger it through the ring. But since both of you managed it so easily, we can skip ahead to application practice.”

“Once you’ve learned to control and use your Flames properly, you’ll go see Miss Loki for an update to your Falna data. If we’re lucky, your Flames might even register as your own unique magic.”

If that happened, it’d be a huge deal.

That would mean a third-party power could be converted into a recognized ability within the Falna system—an enormous loophole.

If that’s possible, then the implications are insane…

He shook his head, pushing the thought aside for now. “Let’s first see if your Flames can actually be recognized by the Falna. One step at a time.”

A door materialized in the middle of the sisters’ room.

Tsuna opened it and stepped through first.

Tiona and Tione exchanged a glance, then followed him in.

The door vanished behind them, and the view before their eyes changed completely.

“This is… Orario,” Tiona breathed, pressing her palms against the floor-to-ceiling window. From this height, she could see the entire Labyrinth City sprawling below.

“It really is Orario!” Tione hurried to her side, eyes wide. From this vantage point, the city looked almost like a living map.

“Then… are we in the Babel Tower?” she asked.

Judging from the view, it had to be—the towering structure at the very center of the city.

“Exactly,” Tsuna confirmed. “This space was modeled after the old punishment chamber beneath the Tower.”

“It’s a kind of simulation—a sandbox of Orario, where I can recreate or modify events for training or strategy planning. Basically, it’s another kind of Challenge Space. Since I built these doors myself, everything inside is under my control.”

He smiled faintly. “So using it for your training is no problem.”

Tiona and Tione exchanged a look. They both understood instantly—

Unlike the public Challenge Space, this one was personal, made just for them. A private battlefield.

“I doubt words alone will help you grasp it,” Tsuna continued. “You’ll learn faster through experience.”

He turned toward the window. “For your first session, let’s start with a group of Minotaurs.”

Suddenly, the ground rumbled.

The twins looked down and saw them—an entire horde of Minotaurs rampaging through the streets of the city replica.

They blinked once in surprise, then identical grins spread across their faces.

“Well,” Tione said, eyes glinting, “what’s the plan?”

Tsuna stepped up to the window, waved his hand—and the glass shattered outward. He stood at the edge, the wind whipping through his hair.

“Come with me,” he said simply.

Then he jumped.

Without a second of hesitation, Tiona and Tione followed, leaping straight out after him through the broken glass.
