Aya Misaki, a first-year Seiran Academy student, pursues Sorority membership under relentless familial pressure, her mother’s legacy casting a long shadow. Rejection ignites bitter resentment toward Nanako Misonoo and Mariko Shinobu, spurring Aya to collaborate with classmates Miyuki Sonobe and Megumi Furuta in systematic bullying campaigns against perceived rivals.

Her manipulations—rooted in seething self-loathing and dread of familial disgrace—focus on dismantling Nanako’s Sorority standing. A longstanding junior-high rivalry with Mariko erupts in volatile public clashes, culminating when Aya cruelly taunts Mariko’s family hardships, sparking a physical fight that leaves Aya hospitalized.

The aftermath forces her to confront the guilt festering beneath her vindictiveness and the isolating void feeding her cruelty. This reckoning propels tentative steps toward repentance: acknowledging her faults, then seeking reconciliation with those she harmed. By the story’s end, her shift from antagonist to uneasy ally mirrors a fractured but evolving self-awareness.

Aya’s journey intertwines societal pressures and gnawing insecurity, tracing how envy corrodes connections and how fractured legacies shape identity. Her arc—marked by downfall, reflection, and fragile redemption—echoes themes of forgiveness and the arduous path to shedding inherited expectations.
