Dense, yet kind at heart. He is oblivious to Tsumiki's crush on him. 

Everyone has a circle of friends they hang out with. But even within a small group there are smaller groups of friends, best friends and, here's where it gets complicated, boyfriends and girlfriends. Sometimes relationships just develop in a way where you're not exactly sure what you are to the other person. Which is the problem Tsumiki has when it comes to Io. Io's as tall and easygoing as Tsumiki is short in both temper and stature, but he also seems to be totally clueless about how she's starting to feel. Yet, at times, he's almost too affectionate. It's just confusing and irritating. And their prankster friends Mayoi and Sakaki aren't much help. Especially Mayoi, as it gives her one more thing to tease Tsumiki over. Hime, the fifth member of their usual gang of five isn't much better, because she's not really well connected to reality anyway. Which leaves Tsumiki stuck in a quandary. Are she and Io just best friends? And is it worth risking that for what Tsumiki wants?<br><br>

Unaired episode 13 of Acchi Kocchi that was included in Vol.6. 

Wouldn't you just love to poke in a relationship between two young high schoolers who have a subtle distance between each other? Of course you would. Tsumiki and Io have this subtle distance that anyone would want to jump in between just to bug them. That's what the other characters are there for. Tsumiki, being a tsundere and all, won't be honest about her feelings toward Io. Io on the other hand is unaware of Tsumiki's feelings, hence the subtle distance between the two. Now, let's watch these two and see what events await them...
