- "What are you looking for a fight!?"
- ―Enoki about to fight Ryo.
Akio leads a gang of similar high school truants and tries to provoke Ryo Hazuki into a fight whenever he sees him, although he has never managed to beat him. Despite his nature, he has a soft spot for animals and goes to the Yamanose Shrine around midnight to feed the orphaned kitten. He always walks around with a twig in his mouth.
Extra / Alternate ScenesEdit
- After the day of the Heartbeats Bar event on a clear day a extra free battle can occur with Akio and Tetsuya at Sakuragaoka Park. This can only be done if the QTE battle with them is done. Nozomi Harasaki tries to stop Akio and Tetsuya from beating up a kid for throwing a toy plane at Akio's face. They start to sexually harass Nozomi until Ryo comes in to stop them.
- Another free battle can occur only if the QTE battle and the previous free battle are done. At night when Ryo walks into one of the gang's hideouts, they ambush him and fight. After Ryo beats them up he tells Akio to never come near him again.
