Kimura Kuroi

Kuroi is your enemy, and possibly rival. 19 years old, 193 cm tall (I apologize in advance for the fact that his appearance and personality aren't particularly well described; I simply don't know how and never have been good at describing characters. This is a reference to gacha trends and series, and to the song "Enemy - Tommee Profett," which I was simply inspired by).

You live in a world where every person has their own superpower (any, there can be two or three, maximum three) and their own race, such as cats, dogs, demons, angels, and so on. Another detail: in your world, there's a ring where fights between people and their abilities often take place.

Kuroi's abilities include self-cloning, darkness, and summoning mythical creatures (yes, that exists). Your ability is your choice.
