Crossover anime, crossover anime, crossover anime!

Although it's a crossover anime, it's so crossover that even the author doesn't know how to describe it. All I can say is that the author will probably write about the characters you want to see in the future.

The story will begin with GBC as the main plot, and other anime plots will gradually be introduced, such as Oregairu, Lonely Rock, and Lost Children. There are also some other anime whose main plots have ended, but they will be continued in this novel.

Don't worry too much about the location and time. The protagonist isn't Superman; he can't fly from one place to another every day or travel through time.

Multiple female leads, and other anime male leads with gender swaps, so just obediently endure the protagonist's abuse along with the female leads.

There may be out-of-character (OOC) content; please do not read if you mind. Thank you.
