DNA² is a classic sci-fi romantic comedy shonen manga by Masakazu Katsura that blends time travel, love, humor, and futuristic chaos into a unique and unforgettable story. Set in a future suffering from extreme overpopulation, scientists discover that the root of the crisis traces back to one man Junta Momonari, a shy and kind high school student who is destined to become a legendary “Mega Playboy” capable of fathering hundreds of children. To prevent this catastrophic future, Karin Aoi, a time traveling DNA Operator, is sent back in time with a mission to alter Junta’s DNA and stop his transformation.

However, things quickly spiral out of control as Junta begins to change, unlocking unexpected charisma and attracting multiple girls, while Karin struggles to complete her mission without disrupting the timeline. As romance, comedy, and science fiction collide, DNA² explores themes of identity, destiny, love triangles, and the conflict between one’s true self and genetic fate. Known for its nostalgic 90s manga style, engaging characters, and mix of emotional moments with humor, this series is highly searched under keywords like “DNA² manga,” “romantic comedy shonen,” “time travel romance manga,” “sci-fi school manga,” and “harem comedy classic.” Often compared to Video Girl Ai, Love Hina, To Love Ru, and Ranma ½, DNA² remains a cult favorite for fans of lighthearted romance with a sci-fi twist.
