Koichi Hirose

"There's something scary going on in my town. If Morioh City is in danger, that means my parents, my sister, and everyone else important to me will have to face that danger. So even if it's scary, I gotta do something!"

- Koichi Hirose. Koichi Hirose is a core ally in the Diamond is Unbreakable arc of JoJo's Bizarre Adventures. On his way to his first day of high school he encountered two strange men and quickly became friends with one of them, Josuke Higashikata. While investigating a seemingly abandoned house he was struck by a arrow and gained a Stand ability, Echoes. After an encounter with a Stand using conman Koichi awakened the first stage of his Stand and became determined to use his new found powers to make sure his family and city was protected from other malevolent Stand users.

A kind, easily scared but nevertheless courageous teenager Koichi often endears himself to others and has befriended several of the Stand users he has come across most notably Rohan Kishibe and Yukako Yamagishi.
