"A researcher of Zeno, a disease that causes the subject to begin to have feelings of wanting to kill others and eat human flesh" "A genius in psychiatry and psychology, 24-year-old man, loves sweets" "He can be explosive in situations of stress or danger, even insulting or threatening, but most of the time he is someone who is calm, friendly and talkative, and can be very empathetic." "Friend of Tsugino Haru, a somewhat apathetic patient of Zeno, and Ushirono Fuyu, another doctor."
