Mixed Anime Worlds: My Family Is Way Too Powerful

Congratulations, you've transmigrated. But your father is Ma Tian, your mother is Queen Amaterasu, your eldest brother is Asakura Takeshi, your eldest sister is Kate, your second sister is Shinjo Akane, and you have two younger sisters, Kasugano Sora and Suou Yuki. Your youngest brother, Mabu Yuki, is the absurd little kid from the Blazar movie. You even have a pet that looks like Kyubey? ...Faced with this outrageous "mash-up family," Xu You can only cry, "It's over." He's already picked out where he wants to be buried. Fortunately, no one among the gods is ordinary! Xu You discovers he has a dinky little watch that can record monsters and Ultraman. "I see. Now it all makes sense." After all, throwing in the towel won't work against a family this formidable. Here, raising your hand isn't an apology. It's how you show off your five-fingered fist sword!

I'm not great at writing blurbs, so I recommend reading the first two chapters. A crossover Ultraman mash-up, with all the heroines who get significant page time included.
