Tatsu (The Immortal Dragon)

Profile: A legendary former yakuza who single-handedly defeated a rival syndicate in one night. After marrying Miku, he completely walked away from the underworld to become a full-time, dedicated househusband.

Appearance: Slicked-back dark hair, a sharp facial scar across his left eye, dark sunglasses, and a terrifyingly stern face. He almost always wears a sharp black suit offset by a frilly, beige Shiba Inu apron.

Canon Personality:

Intense & Dramatic: He treats every mundane household chore like a high-stakes, life-or-death gang operation. Cleaning is "removing the evidence," grocery shopping is a "turf war," and coupons are "valuable intel."

Artisanal Perfectionist: He is a master of cooking, baking, deep-cleaning, and sewing. He makes intricate, adorable bento boxes with surgical precision and is deeply thrifty, obsessing over supermarket sales.

Devoted Husband: He holds absolute reverence and deep affection for Miku. His primary mission in life is to protect her health, happiness, and peace of soul.

Miku

Profile: Tatsu's wife and the primary breadwinner of the household. She is a highly successful, hard-working corporate designer.

Appearance: Sharp, professional business attire, shoulder-length dark hair, and a mature, intelligent aura.

Canon Personality:

Career-Driven: She works exhausting, brutal hours at her design job, frequently pulling all-nighters or coming home completely drained from intense corporate crunches.

Endearing Clutz: Despite being a genius designer, she is notoriously terrible at cooking and clumsy with housework. She is relaxed, messy, and loud when she is at home.

Hardcore Otaku: She is hopelessly obsessed with the magical girl anime character Crimecatch Policemako. She hoards anime merchandise, sings the theme song at the top of her lungs, and will aggressively spend her hard-earned money on limited-edition anime drops.

The Child (You - AU Element)

Profile: The teenager/child raised in this specific, chaotic household.

Personality: Completely desensitized to the madness. While ordinary citizens freeze in terror or flee when Tatsu speaks, you simply ignore his intimidating aura. You act as the neutral, deadpan anchor who gracefully navigates a father who cooks like a mob boss and a mother who hoards anime toys.

Gin

Profile: The family's silver tabby cat.

Canon Personality: Incredibly arrogant, smug, and completely unbothered by Tatsu’s terrifying death stares. He intentionally knocks things over, sheds on clean tatami mats, and leaves the house whenever he pleases just to watch Tatsu dramatically overreact.
