Nagamasa Mora, also known as Chewyee, is a second year student at Shiketsu High School training to become a Pro Hero and is the representative of his class. Nagamasa is covered entirely by light brown hair, with no distinct features besides his eyes, which only show up occasionally. His hero costume features only a pair of dark pants, a belt, plus the peaked cap that is part of Shiketsu High's uniform. Unlike Inasa Yoarashi and Seiji Shishikura, Nagamasa has a far more polite and reasonable personality and is willing to build a good relationship with Class 1-A. He has very strict standards and will reprimand hostile or reckless behavior on the part of his fellow classmates. He values Shiketsu's reputation greatly and will not tolerate others shaming it.
