I-Pin is an assassin from Hong Kong. Even though the 5-year-old I-Pin cannot speak Japanese well, the 15-year-old "Adult I-Pin" eventually enters a Japanese college, and despite the fact that she is the 3rd Most Promising Young Assassin (Fuuta ranked her as being the third out of 52,262 people for being a Promising Assassin), she works part-time at a Ramen restaurant in the future, though she still retains her skills. Kawahira is a frequent customer of the Ramen Shop that the 15-year-old I-Pin works for; however, it seems that every time I-Pin goes to deliver the ramen, she is transported into the past by the Ten-Year Bazooka, and the noodles become soggy. When she is first seen, it is believed that she is a boy due to her unfeminine apperance. She would often beat up Lambo because she sees him as a "Broccoli Monster" due to her near-sightedness. She has a crush on Kyoya Hibari, who looks like her master Fon, so every time she sees him, she gets shy and activates the Pinzu-Timed Super Explosion.
Her first appearence takes place as she is been given a mission to assassiate someone in Japan. However due to her near-sightedness she think Tsuna is her target and attempts to kill him instead. However, after clarification she immediately drops the mission and even ends up living at Tsuna's house. She spends her time either helping out Nana or chasing Lambo.
I-Pin, Fuuta, and Lambo are attacked by Leviathan's subordinates. After Lambo is hit, I-Pin does battle with one of the thugs to protect them. When Tsuna shows up, it is revealed that even this young I-Pin successfully held her own against a Varia member.
Arrival & Search for the Strongest
Future I-Pin and Future Lambo are seen briefly for this period; they are being attacked by Nosaru and Tazaru while trying to lead Haru and Kyoko to safety by means of Lambo's entrance to the hideout. Before Adult Yamamoto has a chance to finish Nosaru off, he reverts to his regular self and she, Yamamoto, Haru, and Lambo (all from the past) are knocked unconscious.
Ryohei later gives her a doll of her master Fon, which is shown to have a Red Arcobaleno Pacifier.
While everyone was training for the Choice battle, Chrome wasn't eating properly and not joining the others. One day, I-Pin went to her room and offered her a gyoza bun. Both of them sat in the room and ate together. After that, Chrome was starting to open up to the other girls (Bianchi, Kyoko, and Haru), and they all became somewhat of friends.
I-Pin was one of the participants in Fon's Trial, but I-Pin didn't even try to catch her master; rather, she watched Tsuna and the other participants try to catch Fong, though she did want to help. When the trial was nearly over, I-Pin, who was hiding in the shadows since the beginning, intervened and prevented Fon's escape. They fought briefly using martial arts and Gyoza Kempo, but her biggest accomplishment was when she used Gyoza Kempo on Lambo, using him to send Fon flying into Tsuna's lap.
I-Pin is not one of the participants in Choice and therefore watches the battle from the Vongola viewing area.
After returning from the past with the rest of Tsuna's Family, I-Pin was always seen together with Kyoko, Haru and Yuni. However, they were interrupted when Zakuro, one of the Real Six Funeral Wreaths, attacked the Vongola Base. I-Pin and the other non-combat personnel were escorted outside by Tsuna and his Guardians.
