The Great Plagiarist of the Crossover World

"If I can't even build a harem, I might as well go back and inherit the family business!"

An ordinary transmigrator, a conscientious plagiarist.

This is the story of a young man raising a Pet Girl in Sakurasou and pursuing his harem ambitions.

It's just that there might be quite a few heroines in the story?

Probably.

Worlds currently available: The Pet Girl of Sakurasou, Saekano: How to Raise a Boring Girlfriend, K-On!, with other worlds and heroines gradually unlocking.
