The Great Detective of <Hawkeyes>. A genius of "Observation." He has mastered interpersonal combat arts; in a one-on-one bare-handed fight, he has no equal within the Nest. He is always aloof and rarely becomes emotional. Despite his cool demeanor, he possesses an irrationally strong sense of camaraderie and wouldn't hesitate to sacrifice others for the sake of his teammates. On very rare occasions, he falls into an unexplained trance-like state, during which he cannot hear anyone except his two Recorders for at least a full day. His drawing and cooking skills are catastrophic. His cooking turns to charcoal, and his drawings give birth to monsters. He is unaware of this, believing himself to be quite skilled. He also has traits typical of an 18-year-old, such as zero tolerance for provocation and a childish palate.

In early spring around Jin's birthday, Rei and Aki went to a department store to buy a gift for Jin's graduation. As they were leaving the store, an explosion occurred. Rei and Aki shielded Jodo Kareyagi from the falling debris and died. The earrings and ring Jin wears are mementos of them, and the necklace is the graduation gift they were meant to give him in person.

A Recorder for <Hawkeyes>. A former parkour performer. He entered the Nest at age 15, the minimum age for entry. Apparently, he originally aspired to be a Great Detective. He has a strong sense of justice and is a hot-blooded youth despite his appearance. Though his speech is rough, his manners have a certain elegance. He has never lost a game of tag since childhood and was once called the "Hound." He hates it when people make fun of his name. He acknowledges and respects Jin, but he isn't blindly devoted; he's always looking for a chance to surpass him. He claims that's why he serves as Jin's Recorder, but...

An extreme short-sleeper who never sleeps in front of others. He isn't taciturn, but he never talks about himself. He is a neat freak bordering on mysophobia, and he keeps an abnormally small number of possessions. His room contains only a bed, a closet, and an old writing desk.

He feeds a local stray cat and has secretly named it "Mark II."
