OVA
Description
Junta Momonari is a sixteen-year-old high school student who stands 1.73 meters tall and weighs 68 kilograms, with reddish-brown spiky hair and a mole beneath each eye. He is afflicted with a peculiar and debilitating condition often referred to as a female allergy, which causes him to experience violent nausea and vomit whenever he becomes sexually aroused by the sight of a woman, whether in revealing clothing, underwear, or even form-fitting athletic wear. This unusual affliction has made him a complete failure in romantic pursuits and has severely damaged his confidence and social standing among his peers.

Despite his outward appearance as an unlucky and somewhat dorky teenager, Junta possesses a kind and ordinary nature at his core. His life takes an extraordinary turn when he is confronted by a girl named Karin Aoi, who claims to be a DNA Operator from a future where severe overpopulation is a critical issue. According to historical records from this future, Junta is destined to become the original Mega-Playboy at the age of twenty-one, a man whose extraordinary sexual charisma and impulses lead him to father one hundred children, each of whom continues the cycle and exacerbates the overpopulation crisis. Karin's mission is to shoot this Mega-Playboy with a special DCM bullet to alter his DNA and neutralize his excessive traits. However, she makes a critical error and shoots Junta with the wrong bullet, one she had personally customized to create a perfect husband, which paradoxically awakens his latent Mega-Playboy powers and makes them exponentially stronger rather than suppressing them.

As a result of this mistake, Junta's powers manifest sporadically and transform him into the charming Mega-Playboy, much to his dismay. This transformation occurs in stages, with an initial unstable version sometimes referred to as Twinkle Junta, a flashy but physically weak form devoid of his female allergy, which later develops into a more powerful Mega-Playboy persona with significant combat abilities. In this advanced state, Junta gains access to potent psychic powers such as telekinesis and teleportation, which he utilizes in attacks with names like the Mega-Playboy Cannon, a concentrated telekinetic blast, and the Supersonic Attack, which creates a supersonic explosion through teleportation. He struggles to control these transformations, as each time he surrenders to the Mega-Playboy persona, his original DNA stabilizes further and the change risks becoming permanent. This internal conflict between his genuine, awkward self and his powerful, charismatic alter ego forms the core of his personal struggle throughout the story.

Junta's relationships with the female characters around him are complex and complicated by his dual nature. He develops a romantic interest in Karin Aoi, who, despite being the cause of his condition, comes to care for the real Junta rather than his Mega-Playboy persona. He also must navigate his interactions with Tomoko Saeki, a popular girl who becomes one of the first targets of his newfound charm, and his childhood friend Ami Kurimoto, who is notably and inexplicably immune to the Mega-Playboy's supernatural charisma. His primary antagonist is Ryuji, a rival who, after being accidentally shot with a DCM bullet intended for Junta, gains the ability to shapeshift and absorb the DNA of others, becoming a powerful and dangerous adversary obsessed with destroying Junta.

Throughout the narrative, Junta's development is marked by his desperate attempts to maintain control over his own identity and destiny. Rather than wishing for the power to charm women, he consistently seeks to remain himself, recognizing the danger his Mega-Playboy persona represents to his future and the future of the world. His journey involves not just battling external threats like Ryuji, but also confronting the internal battle against his own transformed DNA. He strives to prove that he is more than the playboy he is destined to become, and to protect those he cares about without losing himself in the process. Ultimately, his story examines themes of self-acceptance and the idea that a person should be loved for who they genuinely are, not for an artificial or exaggerated persona.
