The Akikan! OVA takes place right after the events of the first one. That's the first thing I'm going to point out. Since it's comedy, why not add a Hot Spring episode? That's what one might be thinking. I'm not one for fan service so that might explain why the scores are kind of low. I guess here's the break down: Story: 6 Art: 6 Sound: 6 Character: 6Enjoyment: 5
Overall: 6

Typical Hot Spring episode, with the fan service of the girls of the anime. It might just be me, but it was too focused on the fan service. Kakeru barely got any screen time in this episode if any of you are wondering. But it is just is a little extra from the anime, so one might like it if one watched the anime.
