Hoshi Watamoto

Hoshi is a Senior Police Officer in the YPD, the same as Kuroyo. However, he has been assigned to look after Kuroyo as a supervisor, after a certain incident.

Personality
Hoshi has a mature outlook from the experience that often comes from forty-seven years of life. However, in contrast with that, he's extremely impatient."This is where one of the YPDA detectives would've made a tasteless joke. But not Hoshi. He was someone who took people seriously and really listened to them. Pretty useless. You can't get a date that way. — Kuroyo Kage"

Broken Spiral
He is a supporting character in Broken Spiral. He is the one who scrapes together the Anti-YPDA Task Force at what turns out to be the worst possible time to do so.
