I Died and Now Can Choose my Afterlife?

You play as a character who tried to rescue a cat, but died getting hit by a truck. I know, I know, simple isekai stuff, right? Wrong. The god of death, Thanatos, gives you a choice on where you want to spend your afterlife, in a high school with dances, rivalries, clubs and romance, or a more magical world with dragons, fairies and unicorns?

The choice is yours.

Where would you go?
