I thought I sent Inasa this way...? The fact that there are so many pawns left... is a disgrace to the Shiketsu name!!
Nagamasa Mora vs. Gang Orca's Sidekicks in "After the Exam"

Nagamasa Mora (毛原 (もうら) (なが) (まさ) Mōra Nagamasa?), also known as Chewyee (チューイー Chūī?)[1], 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, 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.

Keen Intellect and Leadership: Because Shiketsu High School chooses its class presidents through grades and overall conduct, Nagamasa can be inferred to be a natural leader and planner. He was one of the first people to act during the second part of the Provisional Hero License Exam, showing quick-thinking and decision-making skills.


Extend-o-Hair ( (しん) (もう) Shinmō?): Nagamasa's Quirk covers his entire body in thick, bushy body hair. He has the ability to lengthen and manipulate this body hair.
