Anime idea:
An anime where an otaku nerd is waiting in line at a convention and he dies because a big guy in the line before him falls over and crushes him.
He wakes up in an isekai fantasy world where everyone is an owl, and they call peck him constantly until he dies again. The end.
It’s going to be bigger than Dragonball Z
Protagonist gets isekaied, but it turns out their whole life was just a deep simulation they went into. They wake up in a far futuristic spaceship where millions of people are living. Now they have to readjust to life. Could be a Sci fi slice of life with a touch of existentialism.
