I-Pin

I-Pin is a young assassin from Hong Kong, who had been tasked with assassinating a target in Japan. She is also known as the "Human Bomb" due to her special technique, the Pinzu-Timed Super Explosion. This explosive technique is something displayed around Tsuna who was misidentified as her target in the Katekyo Hitman Reborn! manga and its anime adaption. Additionally, I-Pin with help from the Ten Year Bazooka can appear as her future self. Even more adept at martial arts, future I-Pin also makes appearances throughout the Katekyo Hitman Reborn! series.
