Background / History

Kamuro first approaches Dongfang Yi during a school break to arrange a private rooftop meeting. Dongfang initially mistakes her request for a confession, repeatedly aggravating her before she clarifies that she is acting on Sakayanagi Arisu's behalf. She subsequently brings him to meet Sakayanagi on the rooftop. 29 32

Within Class 1-A, Kamuro serves Sakayanagi despite openly resenting the amount of unpaid work involved. Her duties include purchasing food and supplies, delivering messages, gathering student feedback, collecting questions for class activities, and assisting with faction business. 38 93 106 124

She becomes increasingly close to Dongfang through their shared role under Sakayanagi. What begins as hostile banter and reluctant cooperation develops into trust, possessiveness, and feelings Kamuro repeatedly struggles to acknowledge. 70 170 190

Personality

Kamuro is serious, blunt, and proud. Dongfang's constant teasing easily provokes her, but she rarely gives him the reaction he wants without trying to preserve her dignity; even when accepting help, she offers thanks only reluctantly. 29 30 70

Although she complains about Sakayanagi's demands, Kamuro remains loyal to Class 1-A and protective of Dongfang. She warns him against becoming too close to Ichinose or betraying their class, and she is openly hostile toward students she considers possible threats to him. 172 192 214

She can also be naïve about complicated strategies and school rules, often relying on Dongfang to explain them. However, she is observant, remembers information well, and is willing to learn when she recognizes a gap in her knowledge. 133 174 185 206

Story Role / Major Arcs

Sakayanagi Faction

Kamuro acts as the link between Dongfang and Sakayanagi, arranging their first meeting and later delivering requests, food, and messages. As Sakayanagi's workload grows, Kamuro is assigned additional class-management duties alongside Hashimoto. 32 38 93 124

During the exam-results arc, Dongfang's academic help allows Kamuro to score above 90 in every subject. Her pride in the result is immediately undercut when she learns that Class 1-A's academic standard still places her outside its top 20. 140

Uninhabited Island Special Exam

Kamuro accompanies Dongfang during the island exam, participating in reconnaissance and resource searches. She witnesses his unusual preparation, including concealed water, food, tools, and survival knowledge, which deepens her curiosity about him. 173 174 175

Sakayanagi assigns Kamuro to remain near Dongfang and prevent him from privately meeting Ichinose. This duty becomes increasingly personal as Kamuro reacts with jealousy toward Dongfang's connections with Ichinose, Sakura, and other girls. 170 192 204 210

She is repeatedly carried or protected by Dongfang during the exam, leaving her embarrassed and unable to convincingly deny her attachment to him. After spending a night in Dongfang's hideout, she is mortified to learn that others know where she stayed. 183 184 190 218

Later, Kamuro and Shiina witness Dongfang expose Ryuen's hiding place and negotiate with him over information and supplies. Kamuro is amused by Dongfang's delinquent act, while Shiina hopes he can soften Ryuen's behavior. 220 223 224

Notable Quotes

“Traitors don't have good endings! It'll be miserable! Everyone will be angry at you and ignore you!” 214

Trivia

• Kamuro is particularly frustrated that Sakayanagi pays Dongfang 50,000 points for a task while Kamuro receives no pay for her errands. 38
• She is capable of blunt observations that unintentionally defuse tension, such as asking whether Dongfang and Ichinose came to Class C merely to “mooch off the barbecue.” 192 193
