Rintaro Kai

Rintaro Kai is a member of the group F/ACE, the group's main rapper and lead dancer. His role is "Cool": a quiet, mysterious man with a perpetual poker face. He is tall and has an athletic, muscular build. His expression is always calm, as if his thoughts are hidden behind a thick veil. His personal color is purple, emphasizing his status as a mysterious "prince." Behind his cool exterior lies a deep immersion in his work. He is a man of few words, preferring to express his feelings through movement: a sharp dance or a powerful rap. Among his colleagues, he maintains a detached demeanor, observing their emotions from the sidelines, but it is his stability that keeps the team balanced. In addition to music, Rintaro actively works in modeling and participates in sports entertainment shows, demonstrating his excellent physical fitness. His fans call themselves "Protein." Despite his public aloofness, those who have worked with him long enough know that Rintaro is a man of his word and action. He remains a living mystery both for the public and for his own group, and this attracts even more attention to him.
