Background / History

Kamuro comes from a well-off family and maintains a generally good relationship with her parents, but struggles under their high expectations and resentment toward the future they expect her to follow. Her anxiety manifests as kleptomania: she seeks the thrill of stealing despite having no financial need to do so. 931

Arisu Sakayanagi discovered Kamuro's thefts after their enrollment and used the secret to pressure her into becoming an assistant. Sakayanagi's constant assignments, along with a monthly allowance of 200,000 points, gave Kamuro a sense of being needed and helped curb her stealing, though Kamuro resents being treated as a “dog” rather than an equal. 360

Within Class A, Kamuro became Sakayanagi's primary messenger and a respected representative subordinate due to her proximity to the class leader. She relays messages, contacts other students, performs errands, and gathers intelligence that Sakayanagi evaluates. 42 543

When an electronics-store clerk appeared to be using a hidden camera, Kamuro distracted the situation and stole the SD card to prevent further filming. Her evidence confirmed the clerk's suspicious conduct. 59 60

Although she has social anxiety and can be awkward around unfamiliar people, Kamuro is dependable once given a task. She acts quickly, can be considerate of others' safety, and often performs practical care for Sakayanagi without complaint. 59 60 406

Her loyalty to Sakayanagi is complicated rather than absolute. Kamuro recognizes Sakayanagi's manipulation, worries about being replaced, and openly resists unreasonable treatment, yet she also understands the protection and stability Sakayanagi provides. 359 802 909
