Origin
Rhyme is a character from Square Enix's . Her real name is Raimu Bito, Beat's younger sister. Following him after he ran away, Rhyme unknowingly cased the event that took both their lives and had them enroll in the Reaper Game. However, as part of Beat's entry fee with her own never disclosed, Rhyme has no memory of them being siblings. During the game, Rhyme meets Neku Sakuraba and Shiki Misaki, encouraging Beat to have their two groups team up. However, during the fourth day when they head to Towa Tower, Rhyme sacrificed herself to save Beat from a Noise the Reapers placed in the area. Though her death would led to Beat's own demise due to the rules, the latter's life was spared when Rhyme's soul was infused in a Noise pin that manifests as a flying squirrel Noise. By the end of the game, after deciding not to destory Shibuya, Joshua gives Rhyme a second chance at life with her memories restored.
