Akihiko is the owner of the grocery store next door to Onimaru. He spends a good amount of his free time at the ramen shop, hanging out with Miki's mother. He views his friends' goings-on with bemusement, but he accepts that that's the way she is. Ohta is a huge fan of Super Space Battle Team Star Rangers. He is also a skilled graffiti artist. He often takes some physical punishment at random times. When he was little he was often bullied by his classmates, such as forced to confess to a girl he doesn't like at all.
