Bell Chime Boma was sealed within a statue at the end of the war with the humans, with her entire tribe sealing her on the small bells latched to ropes that bound her. Jarmin releases her under the promise that if she helped to defeat the Turboranger, her people would be released from captivity. Transforming into a girl named Rin, she takes part in the scheme of appearing to be chased by Jarmin as if she was a traitor to be saved by the Turboranger. Yohei immediately believes that she is good, but Rin secretly proves her true allegiance when she attacks Seelon at Dr. Dazai's base behind everyone's back. Regardless of the attack, Yohei continues to support her and tries to help her understand that she has supporters.
