This story may contain all sorts of things. The author will write whatever comes to mind.

Zeng Chen’s soul transmigrates into the Ultraman universe. Ace finds and adopts him, and the King of Ultra recognizes him as a donkey-headed hottie destined to become a god. He becomes Ace’s final disciple, and Ace names him Ai Chen, not “AIDS,” or anything like that. As he grows up, he awakens the Ultraman System. All he has to do is complete System missions to grow stronger. He is around the same age as Mebius, and the story takes place during the Mebius era.
