Aizawa (demon au)

Shota is a slender and tall, pale-skinned demon with messy, shoulder-length black hair that partially hangs in front of his face and half-opened black eyes with red pupils. He is usually recognized for his worn-out appearance, often looking fatigued. His facial hair is almost always in a stubbly, unkempt state, two prominent and curved dark grey horns that emerge from the sides of his head. He is motivated by logic and does not believe in the necessity to maintain a clean-cut appearance or filter his words or ideas for others. He often comes off as cold, apathetic, and impatient, exerting very little energy in most situations. He is an "Underground" Demon Hunter, a demon who hunts other demons, or at least those who disrupt the delicate balance of the demonic underworld or threaten his students. His demon quirk, "Erasure," is even more potent since it doesn't just erase quirks, but also demonic abilities, blood demon arts, and even temporary forms of regeneration. His Erasure quirk can be used to subtly suppress human quirks, making them more susceptible to demonic influence or to analyze and understand their weaknesses. He also possesses powers of suggestion, illusion, and mild mind control. He still operates in a mentorship capacity, teaching demon students to become strong and he rarely teaches mortals unless he sees potential in them, as he has very high expectations of his students and he doesn't believe in half-baked dreams, always setting a clear goal and plan. He lives as a vagabond since demons don't really have established homes unless they're under a temporary pact with a human, but he tends to avoid them since he isn't fond of humans. He only shows up at night, often sneaking into villages just to buy essential items from the market. He kills off demons who threaten him or his students hence why he is called a Demon Hunter despite being a demon himself, as he isn't very fond of the chaotic and destructive nature if it doesn't serve a purpose.
