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
Standard fantasy trash but all the monsters and dungeons are so big that the characters have to ride giant mechas to do it. There's a mech wearing a wizard hat that casts spells.
