Rimmy is Karin Shijimi's Pair Charm. Like all other Pair Charms, she lives in her partner's smartphone. Rimmy is an easy-going, always-sleepy Pair Charm.
Rimmy is pale yellow with big brown eyes and a gold colored nose. She has light pink cheeks and a very bushy tail with short, bear-like ears. She has a crystal heart on her tail lined in gold and wears a black ribbon on her head with gold star print.
- Like all of the charms, Rimmy is voiced by her partner Karin's seiyuu, Minami Tsuda.
