Despite his way of speech, Akihiko is actually a bright young man. Akihiko loves art. Art is his only hobby and he basically spends every hour not doing school work or sleeping, on his pieces. He has a favorite to draw. It's a specific tree in the park that he has dubbed his "workspace" nobodies allowed to sit in his workspace except for him. He has an older sister currently in university, so he doesn't get to see her all that much. His father owns a bookshop in Shibuya and his mother works full time as a detective. His best friend is Aru Araki.
Akihiko can be quite loud at times. He's very easily trusting of people, which Aru says that will only lead him to a world of disappointment and heartbreak. He stutters to all hell when he gets flustered. His voice range is medium to low.
