Yes that's 100% true! The other demons eat or prey on humans for various reasons, but never explicitly stated that humans are absolutely necessary for their biological survival.

when it comes to demons eating. Riazen kind the mMazoku's are the only breed of demons that has to eat humans to survive. Other demons could live on other things besides demons. That's why Riazen was so powerful even in his weaken state of starving. When Mukuro fought Riazen he was weak due to him not eating humans.

This is my take on the demons from the anime.
The demons are this incredibly diverse and complicated race that exists in both the Human World and Demon World. And their power levels vary so drastically it’s like comparing ants to gods. You've got demons that are so weak they’re practically harmless and then you've got the absolute monsters that could obliterate cities or even worlds with just a flick of their fingers. And what makes them so fascinating is how their existence ties into this whole ecosystem that’s both chaotic and structured at the same time.
So demons are categorized by classes ranging from E-Class all the way up to S-Class. And this isn’t just a power scaling thing, it’s like an actual social structure. E-Class demons are basically fodder, the kinds you could squash without a second thought. They're usually the ones causing trouble in the Human World because they're weak enough to pass through barriers but not smart or strong enough to do anything significant. Then you have D-Class and C-Class demons who are stronger but still nowhere near the most powerful creatures out there. B-Class demons are where things start getting serious, they're powerful but still leagues below the true monsters of Demon World.
A-Class and S-Class demons are where the real powerhouses are, and S-Class is almost like a mythical status. A-Class demons can wipe out cities effortlessly but S-Class demons are on an entirely different level. They’re basically gods in terms of power and influence, and most of them reside deep within the Demon World because the barrier between Human World and Demon World is designed to keep them out. They have such insane spiritual energy that the barrier can’t even contain them. It’s like their very existence is a violation of natural law within the Human World.
The Demon World itself is just brutal. It's got this whole "survival of the fittest" structure but at the same time it's not just mindless chaos. There’s an actual hierarchy in place and rulers like Raizen, Mukuro, and Yomi are at the top of it. And these rulers aren't just strong, they're practically the embodiment of the Demon World’s history and culture. Raizen, for example, represents the more primal side of demons savagery, instinct, hunger, but also honor and restraint. His refusal to eat humans even when it’s basically killing him shows that he’s not just some mindless beast. There’s a code, a principle that he follows that’s way stronger than any physical craving.
Then there’s Mukuro who’s all about strength through hardship. Her entire existence is this constant struggle against pain and trauma. She's a perfect representation of the brutal nature of the Demon World. Her power and status were carved out of pure suffering and resilience. And Yomi is all about intellect and control. He’s not just powerful in the conventional sense, he’s this cunning, strategic figure who sees the Demon World’s future like it’s some kind of puzzle he has to solve. And what’s crazy is that all of them have their own armies. They’re not just isolated powerful beings. They have followers, they have influence, they have their own ecosystems that are almost like miniature worlds within the Demon World itself.
But before all that, in the human world, demons have always been a threat. And this is where the Spirit World comes in with its own classifications and organizations like Spirit Detectives. The Spirit World tries to maintain this sort of balance or at least the illusion of control by assigning cases to Spirit Detectives like Yusuke. And for the longest time, the Spirit World’s biggest concern is keeping the S-Class demons from breaking through the barrier. But what’s interesting is that the Spirit World’s own policies are rooted in fear and control. They don’t just want to keep peace, they want to keep power. And their classification system of demons almost feels like a method to simplify and label something that’s way more complex than they want to acknowledge.
Demons can also be incredibly human like. You see that with characters like Hiei and Kurama who are both so layered and complex. Hiei is this ruthless, detached fighter who’s driven by his own past and desires but he’s not just evil for the sake of being evil. He’s got loyalty, he’s got his own moral code, even if it's twisted. And Kurama is literally living as a human while being a demon, showing that demons can adapt and even evolve beyond their nature. But at the same time, they still have that primal instinct and hunger. Like Kurama’s transformation into Yoko Kurama, which is almost like this metaphor for how demons never fully lose their essence no matter how much they try to adapt or change.
And then there’s the way demons interact with humans. Some of them want to coexist or even blend in, while others just see humans as prey or tools. But it’s not just about brute strength. Demons have their own cultures, their own societies. Some of them are civilized in ways that completely defy the idea that they’re just monsters. You’ve got demons who are scholars, strategists and warriors. There’s so much variety to them that calling them all "demons" almost feels like an oversimplification. It’s like trying to categorize all human beings under one label.
The Demon World is chaotic but there’s a kind of order to that chaos. Even in a place where power is everything, alliances and pacts and strategies are what really keep things moving. Demons can be noble, they can be ruthless, they can be cunning, and they can be honorable. Their motivations aren’t always just about destruction or power, sometimes it’s about pride, sometimes it’s about survival, and sometimes it’s about proving something to themselves or others.
And when you see characters like Hiei, Kurama, or even Sensui interact with demons, you realize how complicated that whole world really is. It’s not just about good versus evil, it’s about perspective, evolution, and how demons define themselves in a world that constantly tries to simplify them into something manageable or understandable.
Demons in Yu Yu Hakusho aren’t just monsters. They’re beings with their own identities, codes, cultures, and ambitions. And it’s that complexity that makes them so compelling.

I agree! It would've been amazing to see more of Raizen. He's a cool character

When demons evolve to A and S class develop emotions like love and empathy just like humans. I really wish Togashi didn't have to rush the story because there was a lot he could've done with Raizen's character. I mean being the most powerful demon in Demon World and living for many centuries the possibilities are endless.
