7 [Similar Anime] Like Clean Freak! Aoyama-kun

These two shows center around popular main characters who both are known for their perfection and selflessness. Even though the protagonists of both shows have a large and positive backing, both characters on a daily basis face obstacles planted by others as the result of competition, which are always dealt with in unexpectedly smooth ways.

These two comedies follow main characters who are popular almost to the point of worship. However, while Aoyama faces external problems such as competition from others, Handa faces internal problems within himself.

The genre and settings of both animes are quite similar. Both MCs are high school students who are considered geniuses/talented (Aoyama=soccer, Saiki=psychic) and surrounded by people who are obsessed with them, yet the MCs prefer to avoid them (Aoyama being a cleanliness freak while Saiki intentionally maintaining a mediocre image to live a peaceful, normal & average life/lifestyle). Both MCs are also notably serious yet their actions and seriousness make situations more hilarious.

Both are kinda short shoujo comedies with romance (not focused on just one couple) and good art. Boys have the most important part in these two animes.

These 2 animes are so much alike. The main character got the same aura as well as their awkwardness. The background of both of them are kind of similar, but at the same time differs at some factors being for example, they are both different sports.

Despite having contrast personality, the MCs of both anime are quite similar:
-They got the same hairstyle :p
-Similar facial expression (at some moments, I saw Tanaka's face in Aoyama xD)
-Most of the characters understand what person the MC is (In Keppeki Danshi, the other characters understand that Aoyama is a clean freak who loves to make everything clean. While in Tanaka-kun, they know that Tanaka is a lazy boy who needs help from Oota (lol)).

One is a sports anime, the other is isekai - but they have one important thing in common: Seemingly perfect and overpowered main characters with one "little" obsession that turns everything hilariously upside down. Both the MCs have important things they need to achieve, but no matter what their strange obsessions are top priority in every single situation they end up in - and hilarity ensues. In short, if you enjoyed the comedy in one of them, you'll almost definitely enjoy the other one too!
