Background

Raku entered Advanced Nurturing High School as the sole student from his former middle school to enroll there. He claims not to remember that school’s name and describes it as a place where students received only a brief welcome before immediately beginning their studies, rather than holding a conventional entrance ceremony. 6 22

His earlier life was not affluent, leaving him habitually frugal when buying necessities. He has also implied that he was bullied and easily swindled in the past. 6 50

On his first trip to school, Raku met Ichinose Honami on the bus. Though he initially intended to remain unnoticed, her friendliness repeatedly draws him into Class B’s social life and later into its conflicts. 3 5

Appearance

Raku has gray, curly hair and a slender build. Despite considering himself physically unremarkable, Ichinose notes that his muscles—particularly those in his forearms—are unusually firm and developed. 21 11

• Often has an expression that visibly conveys annoyance or reluctance. 45
• Described by classmates as a “slender, beautiful boy.” 37
• His low-profile presence leads some classmates to call him “harmless” or overlook him entirely. 18 41

Personality

Raku openly identifies as an “energy conservation” enthusiast. His personal rule is to avoid unnecessary effort and settle unavoidable matters as quickly as possible. He frequently frames sleep, inactivity, and minimal participation as his preferred responses to school life. 5 22 36

This attitude is contradicted by his actions. Although he complains when pulled into other people’s problems, he repeatedly assists Ichinose, investigates the Class C–D dispute, tutors through difficult situations, and helps with Class B’s island camp. Ichinose considers him gentle but unexpectedly cold, believing he often deceives himself about his own willingness to help. 28 36 44

He avoids direct lies, instead withholding answers or using careful wording when pressed about matters he does not wish to reveal. Ichinose suspects this habit, together with his concealed intelligence and physical ability, reflects an unknown past. 36

Abilities & Skills

Academic Control and Analysis

Raku intentionally maintains low-to-average scores, including repeatedly scoring around the minimum passing mark. Teacher Hoshinomiya considers this pattern suspicious, while Ichinose believes he is much smarter than his grades suggest. 15 20

• Identified the likely author of Shiranami’s unsigned love letter by comparing the handwriting. 26
• Recognized that his testimony in Sudo’s case would only support Class C because he arrived after the fight had effectively ended. 21
• Offered practical assistance with anonymous point transfers during Class B’s information-gathering effort. 28
• Notices details others overlook, including Ichinose’s declining condition before she recognized it herself. 45

Physical Ability

Raku is stronger and more athletic than his inactive lifestyle suggests. 11 23

• Caught Ichinose before she fell on a stairway. 23
• Quickly completed a hammock during the island special exam and helped gather firewood. 44
• Claims that his mobility and awareness are at their best at night. 7
• His abilities remain deliberately understated; Ichinose believes he refuses to display his physical prowess publicly. 36

Traditional Arts

Raku has learned several traditional and artistic skills. 3 5

• Piano
• Tea ceremony
• Calligraphy

Equipment / Items

• Student ID phone — Used for school communications and point transfers. 28
• Plain handkerchief — Raku prefers an unpatterned, practical design. 24
• Necklace — Accidentally bought a women’s-style necklace and gave it to Ichinose for her birthday. 20
• Listening devices and surveillance cameras — Named by Raku among the possessions he considers valuable. 13

Relationships

• Ichinose Honami — Classmate and Raku’s closest recurring companion. They met on the bus, regularly share meals, study together, and work on Class B’s problems. Ichinose is persistently concerned about his health, safety, grades, and self-imposed isolation. 3 8 16 22
• Kanzaki Ryuji — Classmate and friend. Kanzaki attends the club orientation with Raku, shares meals with him, and assists with Class B’s investigations and academic support. 5 9 16 28
• Ayanokoji Kiyotaka (Class D) — A cross-class acquaintance Raku calls a “frenemy.” They became acquainted through an elevator encounter and cooperated during the investigation into Sudo’s assault case. 22 24
• Shiranami Chihiro — A high-achieving Class B student whose confession to Ichinose becomes a source of misunderstanding after Raku advises Ichinose. Shiranami is also notably attentive to Raku despite his low-profile reputation. 17 26 27
• Chie Hoshinomiya — Raku’s homeroom teacher. She confronts him over his carefully controlled grades and repeatedly teases him about his closeness with Ichinose. 15 16
• Kushida Kikyo — A Class D student who seeks Raku’s help identifying another witness to the Class C–D fight. Raku remains wary of her but provides the information he has. 21
• Kouenji Rokusuke — A Class D student Raku encounters in the forest during the island exam. Raku defuses Kouenji’s self-aggrandizing question by insulting the island rather than Kouenji himself. 45

Story Role / Major Arcs

Entry into Class 1-B

Raku enters Class 1-B intending to stay under the radar. His meeting with Ichinose instead establishes him as one of her regular companions, despite his discomfort with attention and social expectations. 3 5 8

Academic Suspicion

After scoring exactly 60 on a quiz and receiving similarly average entrance-exam scores, Raku is summoned by Hoshinomiya. He admits to controlling his performance to meet passing requirements but denies concealing greater ability. 15

Sudo Assault Investigation

Raku becomes involved after being identified as a witness to the Class C–D fight. He refuses to provide misleading testimony because he only saw Sudo beating the Class C students after the confrontation’s main events, but he identifies a second witness: a pink-haired, glasses-wearing girl with a camera. 21

He later assists Class B’s effort to gather information, helps Ichinose use anonymous point transfers, and delivers surveillance footage to Horikita’s group. 28 35

Shiranami’s Confession

Ichinose asks Raku for advice on rejecting Shiranami’s confession without destroying their friendship. Raku’s suggestion that they “date” as part of a hypothetical solution is overheard and misunderstood by Shiranami, who believes Ichinose and Raku are together. 26 27

Island Special Exam

During the island exam, Raku contributes to Class B’s camp preparations despite his reluctance. He completes a hammock, gathers branches for a fire with Ichinose, monitors her health, and promises to help her when she is frightened at night. 44 45 48
