Osomatsu-kun Returns!.When the sextuplet Matsuno brothers; Osomatsu, Karamatsu, Choromatsu, Ichimatsu, Jyushimatsu, and Todomatsu, learn that Osomatsu-kun is getting a brand new anime, they have doubts that their Shōwa era gags will cut it in a modern day anime. Thus, the brothers end up revamping themselves as a colorful bishōnen idol anime, in which they are all handsome idols with unique looks and personalities. However, after performing various feats such as saving the Earth from a meteor and somehow killing Totoko with their charms, the burden of being in a popular anime proves to be too much for the brothers' Shōwa era bodies to handle. Things soon get hectic when more characters appear in their rebooted forms, and the whole thing inevitably descends into a mishmash of parodies and blatant copyright infringement. Forced to go back to the drawing board, the brothers end up spending the next ten years doing absolutely nothing, at which point the actual anime begins.
