Aimi Yoshizumi, an aspiring comedian and self-declared champion of justice, partners with Kaoruko as the superhero duo Love Pheromone, chasing Broadway stardom amid relentless obscurity. Struggling to fund their ambitions, they juggle part-time gigs while moonlighting as reckless vigilantes. Their flashy alter egos clash with reality: chaotic battles against villains spiral into property-crushing disasters, painting them as public menaces rather than saviors.

Their makeshift heroics rely on a jury-rigged combat system activated by absurd mechanisms—like a toilet handle in their apartment unleashing a hidden slide to a mechanized lair. Brandishing the motto “in the name of justice,” they charge into fights with unchecked fervor, mistaking destruction for valor. One such clash backfires catastrophically, unleashing a worldwide catastrophe that cements their legacy as accidental antagonists.

Aimi’s drive stems from a hunger for applause, though her comedic timing falters onstage, littering performances with cringe-inducing punchlines. Disowned by her family for abandoning tradition to chase laughs, she doubles down on her superhero persona, prioritizing theatrical showdowns over strategy or safety. Her interactions hint at fixations on particular physical traits in others, though these quirks remain tangential to her crusades.

Financial woes and public disdain hound the duo, their fleeting brushes with success overshadowed by the fallout of their antics. Their story spirals as ambitions collide with incompetence, their unchanged methods and tarnished reputations lingering long after their final curtain call.
