Background / History

Kiryuin was already burdened by debt from the previous semester when her class's points dropped, leaving her nearly out of private points at the beginning of the new term. This shortage led to her failed payment at Keyaki Mall, where Yagami Shizuka accidentally paid 2,300 points for her purchases. She accepted the favor, gave him her contact information, and promised future assistance within her ability. 8 12

When Yagami asked for information about the school, Kiryuin refused to violate the upperclassmen's gag order without substantial compensation. She initially demanded one million points, then accepted his challenge to a game of Tag instead. Overconfident in her A+ physical and academic ability, she offered him a one-handed handicap while carrying her shopping. Yagami won by touching her backside under the agreed rules. 9 10

Though embarrassed by the loss, Kiryuin honored the wager. Rather than give her information directly, she gave Yagami a signed notebook that was blank except for a pink “Love ya!” written on its final page. The Student Council subsequently summoned her over suspicions that she had leaked information, but she firmly denied the accusation and demanded evidence. 10 12

She later invited Yagami to accompany her for her birthday, during which they spent time at Keyaki Mall and karaoke. Despite inviting him to spend points on her, she bought only a hairband and did not exploit his generosity. Their subsequent outings developed into a friendly, flirtatious rapport. 22 23 40

Appearance

Kiryuin is a beautiful upperclassman with silver-white hair and a notably fashionable, confident presentation. She is associated with long legs and black stockings during her outings with Yagami. 8 22 23

• Silver or white hair. 8 22
• Wore carefully chosen summer clothing for her birthday outing. 22
• Often wears black sheer stockings. 23 39
• Her athletic build and physical strength are apparent enough for her to assess Yagami's increased weight and musculature through a casual pat and inspection. 39

Personality

Kiryuin is exceptionally proud of her abilities and accustomed to being unmatched. She views herself as a “superhuman” in both academics and athletics, initially treating Yagami's challenge as an amusing display of courage rather than a genuine threat. 9

She is pragmatic about points and information, willing to place a high price on knowledge when she is short of money. However, she is not simply greedy: she honored her bet after losing to Yagami, refrained from excessive spending during their birthday outing, and later offered him her old exam papers without charge once he explained his plan. 10 23 40 41

Kiryuin is openly irreverent toward authority. During her Student Council interrogation, she sat with crossed legs, challenged Horikita Manabu's lack of evidence, and suggested that Yagami's acquisition of information should be regarded as proof of his own ability. 12

Her interactions with Yagami are playful and flirtatious. She teases him about Sakayanagi, openly tests his reactions, and pursues him when he tries to evade her advances. 23 40

• She recognizes that information can be indirectly hinted at without directly violating restrictions. 9

Relationships

• Horikita Manabu — Student Council President who summoned her over suspected information leakage. Kiryuin dismissed the accusation, demanded proof, and openly challenged his reasoning. 11 12

Story Role / Major Arcs

Keyaki Mall Encounter

Kiryuin's first encounter with Yagami begins when she cannot afford her purchases at Keyaki Mall. He covers the 2,300-point bill, creating a debt and opening a line of contact between them. 8

Tag Wager and Student Council Inquiry

When Kiryuin refuses to sell school information cheaply, Yagami challenges her to Tag. Her overconfidence and self-imposed handicap allow him to win. She gives him a blank notebook instead of information, which becomes the basis for the Student Council's suspicion that she leaked the intelligence he later shares with Class A. 9 10 12

Birthday Outing

Kiryuin asks Yagami to accompany her and spend points on her birthday. Although the outing lasts through the weekend, she buys little and establishes a more personal, playful friendship with him. 22 23

Midterm Exam Papers

Seeking to repay her debt and assist Yagami, Kiryuin meets him again to discuss midterm exams. She agrees to give him her past exam papers for free after he reveals his plan to predetermine Class A's top rankings. 39 40 41
