Description
Kozue Aoba, the 16-year-old landlady of Narutaki-Sou apartment building at the story's start (birthday December 22), possesses dark blue hair, bluish-green eyes, and a signature style featuring two bangs tied with ribbons and bells. She typically wears a dark blue sailor fuku with a pink ribbon and white skirt.
Her dissociative identity disorder manifests four distinct alternate personalities, triggered by specific emotional states and reverting after sleep or unconsciousness. Each alter displays unique physical traits:
- **Saki Akasaka** emerges from surprise or anger, exhibiting red eyes, a ponytail, a tough demeanor, significant physical strength, and vulnerabilities to alcohol and butterflies.
- **Nanako Kanazawa** appears when Kozue feels embarrassed, behaving like a 6-year-old with yellow eyes and antenna-like hairstyles; she calms when called "Shiny".
- **Chiyuri Midorikawa** surfaces during clumsiness or fear, characterized by green eyes, a side ponytail, a compulsion to enforce cosplay (aided by resident Tamami Chanohata), and the catchphrase "Correct!".
- **Natsume Konno** manifests from sadness, displaying blue eyes, high pigtails, extreme shyness, skill in card tricks, and speech ending in "...kamo" ("maybe"); flowers appear atop her head when happy.
Kozue's primary personality is mature, kind, and responsible, managing Narutaki-Sou while attending high school. She shares a fondness for umeboshi with her alters.
Her condition stems from childhood trauma. The manga reveals this resulted from losing her great-grandfather and subsequent parental abandonment; during this time, her second cousin, 10-year-old Ryūshi Shiratori, unknowingly influenced her personalities through drawings and stories about transformation. The anime offers a divergent origin, attributing her fracturing to guilt over her parents' deaths in an accident during a trip she gifted them.
Her development centers on her relationship with Ryūshi, an art student who moves into Narutaki-Sou. While Kozue remembers their childhood meeting, Ryūshi initially forgets it. Their romantic relationship begins in manga chapter 39. Ryūshi's acceptance of all her personalities aids her emotional healing.
The series concludes with Kozue marrying Ryūshi. They have four daughters, each physically and behaviorally resembling one of her alternate personalities, symbolizing their integration into her core identity.
