Azuki Edomae is the central figure in a trio defending Minamachi City. She bursts with unrestrained energy and impulsivity, frequently disregarding social conventions. Her actions include barging into homes uninvited, consuming others' food without permission, and delivering blunt, critical remarks directly to individuals, such as openly pointing out another's alcohol dependence stemming from loneliness and relationship problems. She displays a notorious lack of modesty, including instances of partial nudity obscured from view.

As Kigurumikku-Swan, she transforms using a specialized "Kigurumi" costume, facilitated by a sentient animal-shaped hat of unexplained origin. This simple transformation process involves changing into distinct outfits, creating a plush doll-like appearance. Her specific power harnesses emotional energy as a weapon, though it sees limited use. The transformation requires collaboration with children, and the sentient hats can be physically repaired like ordinary plush toys.

Alongside Mutsumi Mutsuki (Kigurumikku-Falcon) and Serika Shihodo (Kigurumikku-Swallow), she confronts threats from the antagonistic Kaburimogu organization, battling adversaries like an ice cream cone-shaped mecha. The documented episodes are self-contained comedic segments with no overarching plot, continuity, or character progression; they can be viewed out of sequence without losing coherence, and previews do not accurately reflect subsequent content. Her background, family, life outside heroics, and any development remain undocumented.
