Third season of Honzuki no Gekokujou: Shisho ni Naru Tame ni wa Shudan wo Erandeiraremasen.

An action comedy including parodies of tokusatsu monster/hero genre, such as "Godzilla" and "Ultraman." A time-space conditioner from the future, Miraiman, suddenly appears before the Nohara family, and he requests the family to fight against giant monsters who appear from time-space distortion one after another, in order to save the world from destruction. Every time monsters appear, Shinnosuke's parents, father Hiroshi and mother Misae go to the world three minute later, transform themselves into righteous heroes and defeat them within the time limit of three minutes. Hiroshi and Misae become wrapped up in getting rid of monsters, and Misae stops doing the housework. Then, a strong monster appears, and he cannot be defeated within three minutes. Shinnosuke rises up against the monster.

As summer break comes to an end, Nishikata is stoked to try out his newest pranks and finally outdo his classmate Takagi once and for all. Despite his losing streak, he is slowly getting to know the unrelenting workings of her crafty mind. However, he soon realizes that Takagi's motivations behind her teasing may not be what he initially assumed. One thing is certain, though: each fun-filled day of strategizing and competing brings the two closer than ever.

Shikimori seems like the perfect girlfriend: cute, fun to be around, sweet when she wants to be... but she has a cool dark side that comes out under the right circumstances. And her boyfriend Izumi loves to be around when that happens!
