Background & History

After the death of their mother and their father's frequent absences for work, Seika held the Ijichi household together and cared for her younger sister Nijika. Though she is not domestically inclined, Nijika regards her as an elder-sister figure who has supported the family in crucial ways. 231

As STARRY's manager, Seika initially gives Nijika's newly formed band a vacant performance slot two weeks away, doing so in her usual curt, dismissive manner. She nevertheless continues to oversee the group’s progress and its use of the venue. 14

Appearance

Seika is a blonde woman with a generally taciturn, lazy-looking demeanor and half-lidded eyes. Her subdued presentation contrasts sharply with the frightening anger she displays when provoked. 52 74

• Blonde hair. 74
• Often appears sleepy or indifferent while working. 14 52
• Her calm expression can give way to an intimidating, visibly furious glare. 46 114

Personality

Seika is blunt, stern, and difficult to impress. She maintains a detached exterior even when Kessoku Band succeeds, and she prioritizes STARRY's standards over Nijika's wishes or enthusiasm. 75 104 184

Behind that severity, she is deeply protective of Nijika and attentive to the people working under her. She recognizes Bocchi's musical ability, takes teaching seriously, and opposes Hayato's relationship with Nijika primarily because she fears her sister will be hurt. 52 75 234

Her affection is often expressed indirectly. Seika secretly supports Kessoku Band online, worries about Nijika's feelings, and eventually accepts Nijika's decision to date Hayato while warning him not to mistreat her. 183 225 234

Skills & Responsibilities

Venue Management

Seika manages STARRY's operations, including scheduling, payroll, and staff training.

• Trained Hayato at the front desk, explaining ticket sorting and customer procedures. 52
• Stopped Hayato from over-cleaning the venue after customers complained that he had wiped away its atmosphere. 104

Musical Judgment

Seika assesses performers by their readiness rather than their personal connection to her.

• Identified Bocchi's impromptu playing and singing as potentially professional-level. 52
• Refused to grant Kessoku Band another stage appearance when she judged its skill level insufficient; she stressed that the issue was neither money nor audience numbers. 75

• Later saw Kessoku Band reach first place in an online voting ranking and acknowledged Hayato's capability. 360

Relationships

• Ijichi Nijika — Her younger sister. Seika is fiercely protective of Nijika, though her concern is often expressed through criticism, overprotection, and tsundere behavior. 14 46 225 234
• Ishikawa Hayato — A Kessoku Band member and frequent source of frustration. She trains and employs him at STARRY, but repeatedly clashes with him over his teasing and his relationship with Nijika. After he explains his intentions, she agrees not to oppose their dating, provided he does not hurt her sister. 52 75 231 234
• Hiroi Kikuri — Her junior from university and former bandmate. Seika is regularly exasperated by Kikuri's drinking and irresponsible behavior, but still looks after her. 61 301

Story Role / Major Arcs

STARRY and Kessoku Band's Formation

Seika grants Nijika's group a last-minute opening at STARRY, establishing the band's first concrete deadline. She later allows the members to work at the venue while maintaining professional expectations of them. 14 52

The Stage-Readiness Dispute

When Nijika assumes the band can perform again, Seika rejects the request because the group is not yet skilled enough. Her decision devastates Nijika, but it reflects Seika's desire to prevent her sister from suffering another painful failure on STARRY's stage. 75

Seesaw Festival Recognition

Seika watches the festival livestream in secret, initially trying to conceal her investment in the band. She is impressed when both Ichiri and Hayato receive individual highlight segments, and Kessoku Band ranks second in the festival's popularity ranking. 183 184

Hayato and Nijika's Relationship

Seika discovers Hayato and Nijika discussing their feelings at STARRY and reacts violently, striking Hayato and trying to separate them. Hayato later confronts her directly, promising to take responsibility for Nijika's future and happiness. Seika ultimately agrees not to stand in their way, though she remains wary of him. 231 233 234 236

Beppu Surveillance

Concerned about Nijika's date with Hayato, Seika travels to Beppu with Kikuri to observe them without their knowledge. Her attempt at “righteous surveillance” becomes increasingly awkward after she encounters Hayato's family, who are also following him. 338 343 346
