When Darkness rules… (Hiros’ birthday Adventure)

Nagisa wants to make a birthday surprise for Hiros, so she plans on taking him on an adventure through all sorts of worlds in order to show him how great and different those worlds can be. Though it seems like events are getting a bit unpredictable every time, even for a goddess like her…

Four skimpily dressed figures arrived at one of the biggest doors in the entire Neo-Darklord’s castle. The atmosphere was tense and none of the four knew exactly what lay on the other side. They stared at each other and the door for quite a bit before any of them dared to move closer.

“Come on now, girls! Our goddess has commanded us to take care of the new and true demon lord, so that is what we are going to do!” Roze, one of the four girls, said, trying to encourage the others. “We will show him the best hospitality we can offer! By our honor as succubi!”

“By our honor as succubi!” The other yelled after her, their spirits seemingly lifted up quite a bit. There was still a great bit of nervousness among them, but at least all of them now seemed willing to at least enter the demon lord’s chamber. And that was all Roze wanted to achieve for now. So she stepped forward to knock on the door…

Knock knock

“Come in… I mean… You may enter!” A male voice resounded from within the chambers. For as imposing and commanding as it sounded, there seemed to also lie a bit of awkwardness in his voice, which immediately made the gang of four succubi feel better.

They opened the door and stepped into the room, making sure to flaunt and pose as the lusty and playful succubi that they were supposed to be. It was a large and pompous room, decorated in the most fancy way in a way that would scream ‘demon lord’ to all that saw it. And on the bed sat a single imposing figure, dressed in black and white, that made even the bravest of the four succubi, Roze, shudder in awe.

“Soooo… Did you girls just come to stare or do you have business with me?” The demon lord said, snapping all four of them out of their embarrassing stupor.

“Y-yes. We were sent here by the supreme goddess t-to service you to the best of our ability!” Roze answered, though with the overwhelming presents in front of her she couldn't help but stutter.

“Service me? I am sorry, but I don't think you can…” The demon lord said, but cut himself off mid sentence as he seemingly started to think. “You know what? I could actually use some company. How about the four of you come in and make yourselves comfortable?”

So the four of them took a step closer with fear and excitement in their eyes and…

“Tea is ready, milord.” Clea, one of Roze’s succubus friends, came back into the room holding a tray with five cups and a can of tea in her hand. She then handed each and every one of them a cup of tea, before sitting down on the demon lord's bed as well.

Roze felt like she just missed the last couple of minutes. She was now sitting on the demon lord's bed together with the other three succubi. Since the bed was so massive, that was obviously no problem for them. But for some reason, the demon lord himself was sitting on Roze’s lap, leaning his head backwards against her breasts.

Not that she minded at all, as she was actually coming to his room expecting to service him. She was just a bit… flustered… is all.

“Ahh, great job. That tea really hit the spot.” The demon lord said, leaning back against her boobs a bit more, which was honestly the only thing that seemed to calm her down at this point. Just knowing that the lord enjoyed her boobs was enough for her.

“Hey girls? Do you know why I am the demon lord? Do you even know my name?” The lord asked, stumping the girls a bit as they did not expect a question like that.

“Of course we know. You are Hiros, the Great True Demon Lord Champion. The Goddess of Chaos has personally chosen you as her champion and shown the world that you are one of the most powerful demons in existence. That's why you became the demon lord.” Roze explained, though from his sigh as reaction of the lord himself it sounded like she made a mistake somewhere. “Or am I mistaken by chance?”

“You are not, but there is more to it that you probably haven’t heard of.” Hiros said then let out a soft laugh. “This is not the first time we have met either, Roze. And I have probably seen the rest of you before as well, though I don’t remember it as clearly.”

“Oh? I don’t remember meeting you before. How did that happen?” Roze blinked a few times and readjusted her bra, to make sure her lord could continue to lay softly on her admittingly very large chest. She honestly didn’t think a demon lord using her breast as pillows would be a situation she would ever find herself in, but here she was, enjoying the moment.

“Let me briefly start at the beginning, although I can barely believe that it has been less than a day since then.” The demon lord laughed, leaned back against Roze’s boobs once again and started to tell his story…

…

“Ugh… wow, I am dizzy.” Nagisa said, holding her head after she and her brother Hiros stepped out of the portal. This was definitely a first for Hiros, as he had never actually seen anything harm his godly sister Nagisa in any way, shape or form, so he was appropriately worried.

“Dizzy? You of all people are dizzy? I didn’t think the ride through the portal was that bad honestly. Not much different than usual either.” Hiros gave off dismissively, yet Nagisa didn’t seem to be in the mood for jokes at that moment.

“It’s not the portal, it's the mana around here that’s making my head spin.” Nagisa elaborated and shook her head. The light quickly returned to her eyes and she looked much better than she did a few moments ago, setting an example of how fast a goddess could recover from pretty much anything, even if Hiros still didn’t really know why she had a headache to begin with.

“There is… a lot of black mana in the air.” Nagisa said, still not sounding all that steadfast. Hiros however, looked like this raised another 100 questions at the same moment. “Aren’t you the goddess of darkness? Why would dark mana affect you?”

“It’s because I am the goddess of darkness that this hits me so badly. This is a world where my power is almost limitless. There is nearly no white mana left, so everything boosts my strength. So much so that it is hard to keep my sanity.” Nagisa said, and reached for her head once again. “But don’t worry! I will make this the perfect birthday present for you, no matter what!”

“You two! Humans! Get off the battlefield!” A voice rang out from above the two of them, making Hiros turn to look up while Nagisa only reacted slowly. Above them in the sky two winged and demonic armored figures flew a few meters over the ground and both of them didn’t exactly look friendly. “We are about to fight the last resistance from the Torious Clan. If you get in the way of the divine chosen Demon Lord Rozaket, this won't end well for you.”

“Oh? Divine chosen? And who, if I may ask, is the god that granted him that title?” Nagisa asked politely, though there was something in her eyes that he had never seen before. Something very, very sinister.

“My lady, you can be classed a heretic if you have never even heard of Yaminukles, the god of demons and darkness. Ever since he had won the war against Hikarine, the ex-goddess of light and angels, he has become the only true god. Surely you must have…” The demon soldier explained, though Nagisa’s face just contorted into a more and more cruel smile.

“God of darkness. you say? Are you absolutely sure that he wants to call himself ‘god of darkness’?” Nagisa asked politely, though the malice in her voice was slowly getting out of hand.

“Uhm, Nagisa…? I think you are going a bit…” Hiros said, yet the demonic armored soldiers interrupted him as they shouted. “Are you questioning the authority of the one true god Yaminukles?!? You will be dealt with if this heresy continues.”

“Oh, I don't mind showing you what a ‘real’ goddess can do. Your little wannabe god will look like an incompetent apprentice when I am done with this world!” Nagisa declared, making Hiros gulp. That's it, she looked serious. If Hiros didn’t stop her now, she was going to rampage.

“Listen to me Nagisa! You have to calm down, or else…!” Hiros cried, grabbing Nagisa’s hands and trying his best to look into her eyes. Though her eyes clearly looked like she wanted to let loose, no matter what. It was probably already too late to save this world…

“You little…! To all scouts nearby, I have found heretics that have insulted our god! I will deal with them at once!” The soldier shouted, drew his sword and swooped down from the sky, clearly aiming at Nagisa with his blade. Yet just before the blade made contact with Nagisa’s neck… it stopped.

Nagisa didn’t move at all, her hands were still beside her body. The blade just stopped before her neck as if it was magically repelled and held in place, and then Nagisa stepped forward. She grabbed the soldier's helmet with her right hand and slammed the guy into the ground, causing a huge shockwave as she did.

The helmet had disintegrated underneath her hand by now, so she could take a better look at the guy she just single-handedly defeated. He definitely was a demon, with slightly purple skin and two horns sitting at the top of his head. And now that Hiros looked a bit closer, he finally noticed that he had wings and a tail as well.

“This girl… is dangerous. Everyone… assist me at once!” The demon said, though looked confused immediately after he said that. The other demons in the sky instantly reacted, getting into an offensive formation and coordinating a collective attack on Nagisa.

“Thanks for serving your friends on a silver platter my guy. I have no use for you anymore, so go and be eye candy for my brother overthere.” Nagisa said, picking the guy up from the ground and tossing him backwards, right in front of Hiros’ feet, before she put her hand back on her hips and gave the army of demons a sinister smile.

Hiros, meanwhile, was a bit distracted by the person that had landed by his feet. For one, the soldier's armor shattered completely the moment he impacted on the ground and secondly, he looked less and less manly the more time passed.

His face became softer and cuter, his broad shoulders shrank significantly while the muscles all around his body melted away into nothingness. His waist instantly pulled itself together as if someone tightened an invisible corset, all while his hips, ass and boobs flared outwards to ridiculous sizes. and because that guy lay kind of naked on the floor, Hiros could even watch his manhood shrink in broad daylight while a fresh new slit formed.

The person on the floor still was a demon, but looked more like a succubus than anything else that he might have been before.

After making sure that the girl still breathed, which she did, Hiros' gaze went back to Nagisa, and he had a hard time believing what he was seeing. Nagisa, his mostly passive and somewhat mischievous sister, was decimating the soldiers of that army, one after another. And even while floating in the air without wings, just because she could.

One soldier tried to stab her with a spear, but she punched right through the spear, splinting it in half and hitting the soldier squar in the chest, destroying his armor and flinging him to the floor. Another two tried to pincer her with their sword attacks from two sides, yet their blades simply passed through her body and exited with much more speed than they had initially, hitting each other, shattering their armor and launching them to the ground as well.

Before Hiros knew there were only about three out of a dozen or so soldiers left, all three of them visibly frightened but unwavering. It was clear that they needed to attack together, but before they could move, Nagisa released a huge wave of dark mist around them before disappearing without a trace.

By the time the mist started to settle down a bit, all three of them quickly noticed that they were no longer holding their weapons in their hands. Instead, behind each of them a clone of Nagisa was hovering, raising their specific weapon into the air before smacking each of them down, making them crash into the ground just like the others.

It was pretty obvious to Hiros what Nagisa was doing, considering what had happened to all of the naked soldiers that she had swatted out of the sky. Needless to say, none of them were male anymore, all of them were succubi, and all of them were unconscious.

“Hahaha!” Nagisa laughed as she slowly descended from the sky, looking more like a maniac than she ever did before. “Do you hear me, you wannabe god of darkness?!? I will prove to you how much stronger I am than you by turning all of your underlings into an adoring harem for my dearest brother! Stop me if you can, you coward!”

“N-Nagisa?!? Seriously, something is wrong with you and you need to…” Hiros stuttered, not sure how to calm her down, yet she just skipped towards him happily and smiled.

“Don’t worry about it, I’m fine~ I will make this world perfect for you and turn everyone into a devoted member of your harem. Just watch me~” She said, making Hiros flinch. He really didn’t know how to stop her, so he could just watch as she took his hand and declared while pointing her finger into the sky. “Next stop: Demon lord's castle! I will make sure EVERYONE knows that you are a 100 times more competent demon lord than anyone else could ever be!”

“But I…!” And just like that, the two of them teleported. And only minutes after that conversation, the demon lord's castle fell, leaving only a single male person in the entire building…

…

“I see…” Roze nodded while hugging the demon lord on her lap ever so gently. Hiros leaned his head back into her boobs in response. “Yup, that's how I came here. My sister is still out there, rampaging uncontrollably while she just sat me in here with you guys.”

“I have a question, my dearest demon lord. You said you were mistaken as a human, but you are clearly a… very handsome demon. How is that possible?” One of Roze’s friends asked and Hiros just giggled.

“After she obliterated the previous demon lord, she just suddenly decided that I needed to be the new demon lord. It took her one flick of her wrist and I was no longer human.” Hiros explained with a sigh, then added. “And also, you wanted to know from where I knew you Roze, right?”

Roze blinked a few times at the sudden question, but slowly nodded afterwards and said. “Let me guess… I was that previous Demon Lord Rozaket, and our great goddess Nagisa wanted to make an example out of me by turning me into your harem member?”

Hiros didn’t answer, but his gaze said it all. Roze, however, hugged Hiros a little bit tighter and said. “Listen, we all don’t mind being a servant to someone as great as you. Please, just give us the command, and we will do everything in our power to make you happy!”

“That's so sweet of you.” Hiros sighed and laughed weakly. “But I just hope that Nagisa calms down by the end of the day…”

“No more talk about your sister right now!” Roze declared, sitting Hiros upright in front of her. She then flung him into the bed while pressing her breasts into his face. “We are four busty ladies that are willing to show you the best of times. So don’t doubt our hospitality.”

It didn’t take long before Hiros was smothered from all sides by those succubi’s massive assets. And although his day was really unique, he had a hard time not liking his time in this world when he received a service like this…

---

Hello again, Nagisa Fulkami speaking. I am happy to report that our second adventure of three had been a grand success. I might have gone off the rails a little bit, since I don't remember much anymore. But I heard that Hiros had the time of his life being surrounded by a harem of Succubi. And that's the most important thing.

Thanks again to annomos for this idea.
