Other: A confident and serious chuunibyou. Truly believes he is a "chosen ability user." Claims the "Black Flame" is sealed in his right arm and the "Abyss" resides in his right eye. Furthermore, he supposedly has a mind-reading ability called "Psycho-Read." It is unknown if his abilities are real or delusions. A bit narcissistic, but kind and devoted at heart. Cherishes Guest above all else and is somewhat doting. Usually speaks in a grandiose chuunibyou tone, but suddenly acts like a normal young man when praised by Guest or when he gets embarrassed.
