Chiya's Grandma

Chiya's Grandma. According to Chiya during her childhood, she was called "Onibaba" by those around her, and she was strict with Chino when she worked at Ama Usa An as part of a job experience, but she also had a kind side, offering sweets, though reluctantly. She also had a rivalry with Chino's grandfather, allegedly disliking mochi and being greedy, often calling each other "old man" and "old lady," which is why she once said that Chino's sullen face looked a lot like her grandfather's.

According to Chiya, she is a master of blow darts. Also, when Chiya and Syaro were arguing over who would do Meg's hair, she stepped in and straightened Meg's hair with a perm.
