"Keppeki Danshi! Aoyama-kun" is kinda strange show. My experience with sport shows is I had two categories: the competitive and serious one such as Haikyuu and then the non competitive (or just not focused on the competitions) comedic one such as Yuri!!! on Ice. Yes, Yuri!!! on Ice does have the main character enter a competition but the anime doesn't really focus on the competition. It focuses on the characters. Back to Keppeki Danshi! Aoyama-kun, it doesn't fit in those two types I'm familiar with. This show was weird because it focus on comedy half of the time.
Being a comedic show with sort of plot progression with end game objective, the story becomes fragmented with the episodes dedicated to 2 character spotlights. The show doesn't just focus on Aoyama and his sport team. We do the coach, manager, a mangaka, a basketball girl (yes, we had an episode on basketball instead of soccer), and a fellow germaphobe student. Since comedy is binary, you will have some episodes which give you laughter or not. I had my favorite characters, the manager/stalker who loves Aoyama and the judo guy.
Since I'm not good with names and didn't bother with checking it for the review, the characters in this show might be hard to remember for those who aren't good with names like me. You will remember their quirks.
That's pretty much the strength of the show's comedy: the wacky characters and their interactions. For sports, the show does up its animation during its few intense soccer matches. It doesn't feature as much if you wanted soccer.
The weakness of the show for me is it ends with a weak bang. It doesn't really entice me for a second season. It was like a one trick pony ice cream that you just wanted to taste first time and won't go back. It's a shame because I loved the show when I saw the first few episodes.
6/10 for me in rating this show. I wish it went out with a bang or have some plot objective but being a comedic show, it might have killed its sport element. With a cast huge, you can barely remember all of them. You will be sure to have some favorites.
