This anime has a lot of dicks. No really, everyone seems to get naked all the time! There’s lots of cheap gags and people being caught up in different things. It’s okay, but a lot of the humor seems… puerile? One good thing to note about this anime is that this shows life in college fairly accurately. Students tend to drink heavily, party, and skip class while maybe going to club activities if they have joined due to the fact that high school was so strict for them and they are free to be themselves now. There is very little diving content until episode three and it seems like the series is going to rely on humor to prop up whatever story it is trying to tell until it gets there. We will not be keeping up with this one.
