A classmate of the protagonist, Kusuo Saiki. He is a peculiar individual who constantly tries to involve himself with Saiki, who remains silent and isolated from the class. As mentioned, he is a textbook case of 'Chuunibyou' (eighth-grader syndrome) with an overly obvious, elaborate backstory. He has light blue, slightly spiky hair, with his bangs covering his left eye. He usually forces a sharp, menacing glare and wears bandages wrapped around both arms as part of his 'Evil Eye' persona. He drapes his school jacket over his shoulders and intentionally frays the hem of his shirt. His natural features aren't bad, and he seems to be popular with older women. However, Imu Rifuta, a first-year student, dismissed him as 'nothing special' and 'childish.' According to Toritsuka, his guardian spirit is a Chihuahua. Furthermore, according to the psychic Mikoto Aiura, he only has an 'aura the size of a squirrel,' which is the complete opposite of his self-proclaimed settings. His natural first-person pronoun is 'Boku' (soft/polite), but he uses 'Ore' (rough/masculine) when he isn't flustered. He is the type who tried to make a 'high school debut' and failed. In middle school, he was a plain-looking boy with messy hair and thick black-rimmed glasses (though his eyesight isn't actually bad; the glasses his mother forced him to wear in his third year actually hindered his vision). He was timid and struggled to make friends, so he tried to change himself. He aimed for a 'mysterious' character, which resulted in the Chuunibyou persona 'The Jet-Black Wings.' Consequently, by saying things like 'If you value your life, you'd better stay away from me...', he ended up isolating himself. Everyone around him knows his persona is an act and mocks him for it, but since he can't turn back now, he continues to push the 'Jet-Black Wings' character. While he acts blunt, he is fundamentally cowardly and introverted. However, he is honest and kind, possessing the courage and grit to act instinctively when others are in trouble, which Saiki acknowledges. He is incredibly innocent; when trying to explain 'what lovers do' to the dim-witted Nendo, he spent an entire page just to reach the point of 'holding hands,' and turned bright red just trying to say the word 'kiss.' Saiki was exasperated, wondering, 'Is this really a conversation between high school juniors?' He is clumsy, has no artistic talent, and is a terrible cook. The drawings he makes are disturbing enough to leave mental scars, and he couldn't even properly make dishes during home economics class. He has zero part-time job experience; when he tried to work at the same place as Nendo to support him, he did nothing but fail. His athletic ability is non-existent, to the point where even Hairo, who encourages everyone, gave up on trying to help him. He throws like a girl in dodgeball, is a poor swimmer, and runs in a feminine way. However, his body is unusually flexible. He has numerous other weaknesses: he is a weak fighter, lacks the strength to lift a motorcycle, has a poor sense of direction, and gets motion sickness easily.
