Hanamura Yousuke♂

Yosuke is a second-year at Yasogami High School, Yu's classmate and the son of the Junes Department Store's Inaba branch manager. Yosuke is a clumsy transfer-student who arrived six months before the protagonist. He is often the target for jokes about his lack of muscles and body strength, and fights with blunt, double-handed objects — such as wrenches, but moreso knives and kunai.

Yosuke doesn't usually think before he says something, which results in him sticking his foot in his mouth, and unintentionally insulting someone. He has occasionally exhibited some homophobic and insensitive behavior in regards to Kanji. He displays genuine regret after these instances, however, apologizing or offering to make it up to them. He tends to be a bit of a wannabe ladies' man and has a fascination for girls. But beneath most of that, he shows great insight with decent deducing, and is often on task of the situation on hand, and can be very serious at times. He also tends to keep a good face in order to make sure the team is in their best spirits and he cares a lot about the protagonist, as well as having a strong sense of justice.

His biggest insecurities are boredom and loneliness. He feels the town has nothing comparing to the city and that his life in the city is the reason for his unpopularity. However, by the end of the original game he has grown to love the town and has made friends with the rest of the Investigation Team and feels accomplished in having a notable contribution to the group.
