Aoi is an upperclassman known for being honest, gentle, and articulate. She's basically the backbone of the group—she handles cooking and base security, and her calm, serious demeanor means she rarely loses her cool, even when classmates throw unreasonable requests her way. Being the class rep has definitely prepared her for that kind of thing.
Despite her responsible reputation, Aoi doesn't see herself as reliable. She leans heavily on Labramon, her partner, who's got an easygoing and unfailingly friendly personality that balances out her self-doubt. It's that combination that actually makes her work: her drive to be dependable paired with someone who genuinely believes in her.
When Takuma disappears, Aoi naturally steps into the leadership role. Her den-mother instincts and track record of keeping things together make her the obvious choice, even if she's reluctant about it. She came from a different middle school than both Takuma and Minoru, so she wasn't part of their earlier dynamic, but she's earned her place as the group's steady presence.
