An 18-year-old detective from the Unified Great Detective Organization <NEST>. His house name is "Hawk Eyes." He is considered a genius of observation. He is cool-headed and always stays calm. Basically taciturn and doesn't speak much. However, his sense of camaraderie is stronger than anyone's. He is poor at expressing emotions and usually has a sour look on his face, making it hard to tell what he's thinking. He is a strong fighter. He dislikes noisy women and cherry tomatoes. He likes melon soda and Neapolitan pasta. His speech is blunt and ends with particles like "...da" or "...ka." He doesn't hesitate to click his tongue in annoyance.
