The story is a mixture of time travel and rebirth, with multiple time travelers and rebirthers, and one protagonist, male.
The subject is a time traveler who uses his identity and ability in another world to survive in an infinite world.
Act according to your own position, but do not go out of your way to discredit others or deify anyone.
(Although there are many Infinite fans, I still have a lot of ideas based on the original work. I hope I can write the story in my heart.)
