Seki is a 16 years old boy with messy black hair and sharp, small black eyes. His childhood friend is called Shizumi, although they are no longer seeing eachother. Seki has a permanent scar on his nose, which is usually covered by a bandage and he doesn't want people to talk about it. Seki is usually calm and chillgoing, but he wouldn't doubt on hitting those who mess with him or his friends. His family died in a fire accident, yet he only remembers his father and not his mother.
