Isekai Mario is an unofficial freeware fan game that adds anime characters to the world of Super Mario. You can play as hundreds of different anime characters and collect hundreds of power stars in this 3d platformer.

One day, summoning magic was discovered in the Mushroom Kingdom, and with that, the ability to summon those from other worlds is now possible. Unfortunately, things take a turn for the worse. The magic goes out of control, and all the citizens of the Mushroom Kingdom start reincarnating into random anime characters. It is now up to Mario to learn how to use this summoning magic himself, and bring things under control.
