I didn't get a class, so I picked my favorite and saved their world.

Blake Winters was a school bus driver but after he heroically gave his life to protect his students, he was sent to a new world to be a hero there, but the gods forgot about him at first, visiting him as he rested for the first time, they let him pick a class, and he chose his favorite one from a TTRPG, and tasked him with a mission.
