DNA² is a sci-fi romantic comedy shonen manga centered on Junta Momonari, a shy high school boy whose DNA carries the potential to turn him into a legendary super playboy destined to overpopulate the future. To stop this outcome, Karin Aoi, a time-traveling agent from the future, is sent to prevent his transformation — but her plan goes wrong, triggering Junta’s gradual evolution into the charismatic and dangerously attractive “Mega Playboy” instead. Blending time travel, romance, comedy and light science fiction, the story explores identity, attraction and the contrast between gentle sincerity and overwhelming charisma. Known for its classic 90s manga style, playful tone, love triangles and transformation gimmick, DNA² attracts readers searching for romantic comedy manga, time travel romance, sci-fi school stories, multiple heroine dynamics and nostalgic shonen romcoms. Often compared to Video Girl Ai, Love Hina, To Love Ru and Ranma ½, it stands as a cult classic of romantic sci-fi comedy with heart and humor.
