Anime Crossover: The Beautiful Girl I'm Trying to Conquer is a Little Off

[Multiple female leads] [Invincible protagonist] [Pure and satisfying] [Non-Japanese male lead]

Lu Ming, from the world of high martial arts, obtains a system that allows him to travel to anime worlds. He can obtain different rewards by conquering these worlds.

However, these anime seem to be somewhat niche...

For example, "About My Brother and I Living Together in a Small Town."

Or, "My Devil Club Story is Really Problematic"

Or perhaps, "The Story of the Tsundere Student Council President and His Naturally Dark Twin Sisters"
