Natsuki is the top female karateka at her high‑school, a beautiful and cheerful student who charms everyone she meets. While many of the young men in her class would love to be her affection’s target, she devotes her energy to karate. However, she frequently encounters big, ugly thugs who challenge her, giving her continual opportunities to apply her skills. As the series progresses and her opponents grow increasingly formidable, Natsuki studies Akido and Judo, learning new techniques and developing a special Ki‑based energy blast that doubles the power of her punches. Though she cannot demolish walls like some of her foes, her signature move, the N.G. Bomber, consistently sends opponents flying.
