Background: Kyo was unfortunate enough to end up as a hostage during a robbery when he was pretty young. Though he was eventually saved and the robber was arrested, his vocal cords were cut at some point during that time. 

Aside from that, he lives a fairly ordinary life, though his parents are often busy and tend to get home late. He does very well in school, but doesn’t seem to spend a lot of time with other people outside of school. 

Stereotype: Emo/Gamer
