Hajime Nagumo

Hajime was a complete otaku and always came to class with a sleepy expression. He was always bullied and was disliked by both of his male and female classmates for being close to their idol-like classmate Kaori. After wishing for his annoying classmates to be summoned to another world, the next thing he saw was they were on top of a pillar like structure in another world to become heroes.
