Chairoikoguma is a new character introduced in 2016 from the Rilakkuma series, created by the Japanese stationery brand San-X. His name means "Small Brown Bear" in Japanese. Chairoikoguma is a shy, gentle, and honey-loving bear cub. He is often seen with a honey jar.

Though initially timid, he gradually opens up in front of Korilakkuma and Rilakkuma. He is loved for his kind, docile nature and delicate emotional expressiveness.

$GUMA is inspired by Chairoikoguma, wanting only to give you a hug, share some honey, and remind you to take a deep breath.
