Yugami no Toriko

Tanaka is a delinquent so feared throughout his school that he has earned the nickname Mad Dog, fighting daily as rumors about him spread through the halls. Everything shifts when an unremarkable, gloomy girl in glasses appears, someone who shows no fear of him and instead manages to irritate him with nearly everything she does. She tells him that the way his face contorts with emotion strikes her as adorable, and her strange presence gradually pulls Tanaka into her unsettling grip. (Source: K MANGA)
