Honkai Impact 3rd: This World Is Utterly Absurd

[Anime crossover + multiple heroines + invincible protagonist + mostly everyday life + Honkai Impact 3rd + Genshin Impact + making films + developing games + whatever the author thinks of adding + reader suggestions welcome]

Mu Hongyu unexpectedly arrives in this world and discovers that it’s utterly absurd. It has characters from games like Honkai Impact 3rd and Genshin Impact, as well as characters from anime and manga.

I thought this was supposed to be an everyday-life story, so why is the System making me fight? What happened to my peaceful daily life?!

What kind of ridiculous world is this? Still, everyone’s hopes are resting on my shoulders. I can’t lose.
