The Host tells the adventures of some teenagers who have supernatural abilities. They were accepted into a prestigious academy, not knowing that their future would be marked there. It brings us our main protagonist, Kurayami Kanzen. A shy and awkward young man with a passion for the unknown. He is intelligent and spends his time writing in his notebooks. He has black hair that reaches a little below his chin, sky blue eyes, pale skin, and a rather slim physique. He's a bit of a dork.
