18+ Saitou-kun wa Esper Rashii

Saitou, a rather arrogant kid, announces his super power to his class on the first day of high school. He imagines that it will make all the girls swoon, and he'll be crazily popular. Unfortunately, his ability to bend a spoon looks more like a cheap trick than a super power, and everyone laughs in his face. Soon he learns that he is not the only kid with superpowers at the school, and there is even a Super Powers Research Club. He soon finds himself dragged into the society of a friendly invincible girl, a violent telekinetic girl, and a mind-reader. Rather than being swooned over, Saitou appears to have the least impressive ability of the group! Is there any way for him to get the happy high school life he was hoping for?
