Background / History

Watanabe enters Advanced Nurturing High School as a Class 1-D student. On the first day, he gives his bus seat to an elderly woman and meets Kushida Kikyo, immediately recognizing her friendly expression as insincere. He also shares a familiar exchange with Kouenji Rokusuke, implying they attended middle school together. 1 4

He begins the school year with an unusually large private-point balance of 3.1 million. While refusing to disclose information protected by a non-disclosure agreement, he arranges an 80–20 point-sharing arrangement with Kouenji. 4

Hayabara claims that his placement in Class D followed an incident of “excessive self-defense” in which four people were sent “to paradise.” He further implies that his family status is connected to a conglomerate, though the full extent of this background remains undisclosed. 16

Appearance

Hayabara initially presents himself as a handsome, short-haired student with a mild demeanor, typically wearing non-prescription, blue-light-blocking glasses. 2 11

• Athletic, muscular build visible even beneath his uniform. 15
• Uses glasses as a personal “seal” and a remnant of his past rather than for vision correction. 44
• Removing his glasses reveals sharper features and draws considerable attention from female classmates. 10 46
• Breaks his glasses after Airi Sakura reveals her identity, adopting a more openly sharp and aggressive presentation. 44

Personality

Hayabara is observant, patient, and highly interested in the gap between people’s public faces and private motives. He often maintains a polite smile and courteous manner while privately assessing others as tools, threats, or sources of entertainment. 1 7 33

He is calculating and transactional, routinely using private points, blackmail, information, and staged incidents to gain leverage. His willingness to manipulate Kushida, Kamuro, Ryuen, Sakayanagi, and Akito demonstrates that he prioritizes utility and control over conventional morality. 6 16 18 50

Despite his indifference toward Class D’s promotion at first, Hayabara takes an active interest in individuals he considers promising. He challenges Horikita Suzune to pursue Class A for her own growth rather than her brother’s approval, protects Airi Sakura’s self-acceptance, and recruits Akito Miyake after arranging both his predicament and rescue. 21 44 50

Story Role / Major Arcs

Establishing Leverage

Hayabara begins building influence through point-based deals, first with Kouenji and then with Kamuro. He obtains surveillance capabilities by modifying his communicator, establishing a foundation for later blackmail and evidence gathering. 4 6 12

Class C and the Midterm Schemes

After meeting Ryuen through Shiina, Hayabara forces a point transfer, defeats Ryuen in combat, and becomes involved with Ryuen and Sakayanagi’s midterm-paper arrangement. He later proposes backup examination papers to preserve an appearance of fairness. 11 18 23

Guiding Horikita Suzune

Hayabara intervenes when Horikita Manabu confronts Suzune, defeats Manabu in close combat, and exposes Suzune’s dependence on her brother’s approval. He later offers to assist her only if she pursues self-improvement and helps remove harmful elements from Class D. 19 21

Expulsions and Class D’s Internal Crisis

When Class D faces potential expulsions, Hayabara refuses to spend indiscriminately but ultimately pays 100,000 points to cancel Ijuin Wataru’s expulsion. His actions reinforce his reputation as both capable and dangerously rational. 29 30

The Miyake Case and Student Council Appointment

Hayabara provides altered audio evidence against Ryuen, helping clear Akito Miyake during the Student Council judgment. Horikita Manabu subsequently places him in the disciplinary committee as Public Morals Committee Member and Vice Secretary. 45 48 49
