MTL - Pokémon World’s Male Mother - Chapter 520 Kuailong Temple

I was a failed experiment

A skilled but unfortunate modern-day assassin was killed in a freak accident. However, he soon found himself summoned to another world by an evil wizard, who had him possess the body of a boy as an experiment. After successfully planning the evil wizard’s downfall, he used the wizard’s body as a springboard to gain influence and power in his new world.

I became a mage character from my favorite game.
