Description
Miku is a dedicated professional designer whose demanding career enables her husband Tatsu, a former yakuza member, to embrace his role as a full-time househusband managing all domestic duties. Her job often requires overtime, leaving Tatsu to handle the household independently for long stretches. Personality-wise, she presents an energetic and sometimes foolish disposition for her age, forming a stark contrast to Tatsu's intimidating aura. Despite their differing lifestyles, their relationship remains happily married with mutual affection. This dynamic positions Tatsu as the frugal, methodical partner to her impulsive spending nature, especially evident during shopping trips – a Savvy Guy, Energetic Girl pairing.

Beneath her cheerful exterior lies a fervent secret identity: she is an intense otaku fan of the magical girl anime "Policure," enthusiastically collecting merchandise like limited-edition DVDs and figurines. New releases or rare items trigger visible excitement. This obsession creates humorous situations, such as Tatsu's attempts to procure a Policure Blu-ray for her birthday or her strong reactions to damaged collectibles, like when Tatsu buried a broken figurine after a child accidentally damaged it – a gangster-influenced solution she didn't explicitly challenge.

Miku possesses hidden depths. She demonstrates surprising physical strength in comedic moments, like clotheslining Tatsu hard enough to send him flying meters, showcasing a Badass Adorable trait. She can also be unintentionally unsettling, matching Tatsu's creepiness at times, fitting the Beware the Nice Ones trope. Typically acting as Tatsu's Cloudcuckoolander's Minder to ensure social norms are followed, she loses her composure over Policure fandom or high-stress domestic scenarios, such as confronting a cockroach infestation where their reactions align.

Domestically, she is a Lethal Chef, inheriting a brutal cooking style from her father that involves violently attacking ingredients and haphazardly combining fridge contents, resulting in unpalatable dishes. Consequently, cooking duties fall to the Supreme Chef Tatsu. She exhibits impulsiveness in spending, particularly on hobbies like gaming, and may childishly whine if Tatsu deems items too expensive.

Her character portrayal varies across adaptations. The manga and anime depict her and Tatsu as childless, living in a cramped apartment. Conversely, the live-action drama introduces a daughter, Himawari, making Miku a mother and placing the family in a detached house with a yard.

Miku's influence is pivotal to Tatsu's reformation, motivating his dedication to domestic life despite her frequent work absences limiting direct daytime interaction. She asserts authority when necessary, physically intervening to stop his overreactions, such as preventing him from performing yubitsume (finger-cutting) as atonement for a gift mistake.
