After a fight with delinquents, a teenager is suddenly transmigrated to the anime he once liked as the popular antagonist.

He discovers through the system that the fate of the characters goes to shit in the final season, including the one he currently owns, and to change that, he has no choice but to destroy the plot that all.

To achieve this and live happily, he arbitrarily decided to remove the heroines from the original protagonist, kill the Emperor, the true final villain and become the hero who stopped the evil plans of the progenitor of demons.

A mission that seems impossible...but fortunately, his new body is talented and a superior noble, so it will be easy...or so I thought.

Note: The protagonist won't really be collecting women as if they were Pokémon, but yes, he will have a lot of fun. And I think it's obvious, but here, the gender change is not suffered by the protagonist...(She will also be a heroine, so if you don't like her...bye?😀)
