I Ride the Otaku-Friendly Gyaru Titan

A reincarnated otaku enters a world of academies, armored machines, and fantasy warfare—burdened by three harsh constraints: he is an otaku, he has painfully low self-esteem, and he was born a commoner. With nothing but a fragile heart and an unexpected bond with a gyaru-like Titan, he must find a way to survive, grow, and maybe discover a pure love in the cockpit of war.
