I-Pin

イーピン

I-pin is an assassin from Hong Kong who speaks exclusively in Chinese. Although this five-year-old girl cannot speak Japanese, the fifteen-year-old "Adult I-pin" eventually enrolls in a Japanese college. Despite being one of the most promising young assassins, she works part-time at a Chinese restaurant ten years later. She has a crush on Kyoya Hibari, who resembles her teacher.
During times of extreme stress, she clings to the nearest person, and a clock appears on her head; when it reaches zero, there is an explosion like a bomb.
