Background

Kamuro enters Advanced Nurturing High School as a Class 1-A student and is seated beside U Amakusa. Their first interaction begins when U recognizes her name without an introduction and deliberately acts perverted until she agrees to accompany him to a café, intending to retaliate against him afterward. 2 3

Her early association with U becomes more direct when she records his confrontation with Hikaru Tanaka, enabling his extortion scheme. Though initially unwilling and openly disgusted by his methods, she agrees to help after he tells her she is his type. 6

Kamuro later searches for a missing orange cat with U after receiving a call from Emi Miyata. Despite her skepticism and embarrassment at his masked, loudspeaker-based search method, she works with him until they locate the cat in a park. U ultimately adopts it and names it Orange. 14 15 17

She is described as having kleptomania and is eventually caught shoplifting beer from a convenience store. Both U and Arisu Sakayanagi obtain evidence of the theft; Sakayanagi subsequently considers using it to recruit Kamuro as her subordinate. 24 45 49

Personality

Kamuro is blunt, strong-willed, and quick to confront behavior she finds unacceptable. She repeatedly calls U a pervert, refuses to be swayed by his implausible explanations, and responds to his provocations with physical aggression. 2 4 5

Despite her temper, she is observant and capable of rational thought. She recognizes the abnormality of the school's generous point system and is cautious enough to consider surveillance cameras before fighting U. 5

She generally keeps a distance from others and uses polite formalities even with girls, but becomes unusually natural around U despite their frequent arguments. Her hostility toward him increasingly mixes with embarrassment, shyness, jealousy, and concern. 13 16 30
