Teruki Hanazawa, born April 13, is a 14-year-old esper who once styled himself the "shadow boss" of Black Vinegar Middle School. Isolated in childhood by his psychic gifts, he grew to view non-espers as inferior "commoners," his narcissism fueled by a lack of mentorship and Claw’s botched recruitment via artificial espers. A humiliating defeat by Shigeo Kageyama dismantled his ego, exposing his moral flaws and triggering a profound shift. The loss—paired with his school’s destruction and partial hair loss—sparked a journey toward humility and introspection. Initially wielding telekinesis for dominance, he strategically leveraged his powers to climb social and academic ranks. His arsenal includes barriers, telekinetic blasts, and rapid mimicry of techniques like pyrokinesis, Air Whip strikes, and Ethereal Bodies clones. A psychically enhanced necktie functions as a blade, cleaving through structures with precision. Post-defeat, he embraced rigorous physical training, refining his athleticism and balancing offensive prowess with defensive tactics. Rejecting past elitism, he adopted Shigeo’s philosophy of restraint, vowing never to misuse his abilities. Yet traces of his competitive nature linger, flaring in moments of defeat. Living alone due to his parents’ overseas assignments and Claw’s relentless targeting, he developed pragmatic combat instincts, including interrogation tactics. He becomes pivotal in thwarting Claw—rescuing Ritsu Kageyama, coordinating allies in decisive battles, and tempering Mob’s destructive outbursts by prioritizing civilian safety over aggression. His physical evolution mirrors his inner growth: battle-induced hair loss led to a brief wig phase before he embraced a shorter, simpler style. Once rivals, he and Shigeo forge mutual respect, influencing Teruki’s hobbies like bicycle touring. He mentors Ritsu, warning against overreliance on powers. Confident and leadership-driven, he retains a reformed self-righteous streak. Personal quirks include a distaste for raw oysters after food poisoning, a fondness for rock music and films, and a distant familial rapport. His motto shifts from proclaiming himself the "world’s center" to embracing ordinariness—a symbol of his integration into collective humanity without erasing his distinct identity.
