Kardia

Introduced as a fresh face expanding the Koji no Bōken universe in the special short "Audrey's Cousin Kardia", Kardia adds a new flavor to the household dynamic. Kardia is designed to be the ultimate tease, carrying a vibe that heavily contrasts with Audrey's easily-irritated nature. She is highly confident, playful, and possesses an incredibly smug, mischievous attitude. She thrives on catching people off guard especially Koji. Unlike Audrey, who can get flustered by things like extreme heat, Kardia stays completely cool, using her alluring charm and expressive body language to effortlessly control whatever room she walks into. Rather than grinding out a structured 9-to-5, Kardia’s role is that of a bold, opportunistic visitor who lives in the moment. When she isn't acting as a model or a lifestyle influencer type, she loves sticking her nose into the household's business, treating her visits less like a family duty and more like a personal playground. Her introduction immediately shakes up the social hierarchy. While she shares a playful, highly competitive family bond with her cousin Audrey, her main target is Koji. She wastes zero time testing his boundaries, generating instant comedic tension with the rest of the household. Her unapologetic, flirty confidence leaves the other girls especially the possessive Hannya scrambling to reclaim the spotlight.
