Ultraman: After Quick Transmigration, I Became Belial and Just Want to Go Home

[Content warnings: a kind-hearted protagonist, out-of-character characterization, poor writing, a System, and the weakest protagonist in history]

Bai Liya never imagined that one day he would die in the most humiliating way possible, only to transmigrate after death and become an antagonist from the Ultraman series: Belial.

System: “Hello. You're dead.”

Bai Liya: “Huh?”

System: “But I'd like to give you a chance. If you correct the storylines that went wrong in each world and put everything back on track, you can return to your original world.”

Bai Liya: “And what if I fail?”

System: “You'll be trapped in the mission until you die.”

So, in order to get home, Bai Liya began traveling through one mission after another.

What? He has to face Taro from the start? No big deal. Ever heard of a plot-mandated death?

Nearly dying at Zero's hands?

No big deal.

What? He opens his eyes again, and Zero is right there?

Sure, I have to hold back and let him kill me, but no big deal.

What? He opens his eyes again, and his armored self is asking him to hold back and lose to Zero, only for him to die at Zero's hands again? No big deal.

What? From the start... Oh, I see. I've been separated from Belial, and all I have to do is team up with the main cast to defeat him in the end.

In the most broken of all the worldlines,

It wasn't until he was about to complete his final mission that Bai Liya realized it had all been a conspiracy. In the eyes of those who stood above everything, even being alive was a luxury for him. Maybe he couldn't even manage that.
