Chiya Ujimatsu

Blood type: O, Birthday: September 19, Height: 157 cm, in the same grade as Cocoa.

She is the poster girl for the Japanese-style café "Ama Usa An" and was in the same class as Cocoa during their first and second years of high school. She has long black hair styled in a princess cut. She wears a kimono and boots as her work uniform, but also wears Western clothes as her casual attire.

She has a caring personality befitting her elegant appearance, but she is somewhat prone to jumping to conclusions and can easily become depressed over minor things. She developed a liking for pranks when she was happy to see her mother's surprised reaction as a child. She has been childhood friends with Syaro, often supporting her, but also frequently teases her because she finds Syaro cute (or rather, amusing), which often results in Syaro getting angry at her.

Her hobby is making Japanese sweets, and she enjoys giving them original names like "Moon and Stars Reflected in the Sea" (shiratama chestnut zenzai) and "Triple Jewels of the Capital of Flowers" (anmitsu + dango), but she puts these names on the Ama Usa An menu without explanations, which confuses Chino and Rize. However, Cocoa was able to understand them well enough. She took an immediate liking to Cocoa when they met and even invited her to pack her bags and come to her house, and once misunderstood something Cocoa said about class assignments, leading her to cry in front of Syaro, thinking she wouldn't be sad even if they were in different classes. She is concerned about not having coworkers like those at Rabbit House, often playing "Rabbit House pretend" at the café, and deep down, she wants to invite Syaro to join Ama Usa An. When Cocoa went back to her hometown, she even suggested an "Off-season Cocoa Festival," showing she is as much of a Cocoa-holic as Chino.

Her knowledge of magic and the occult comes from her grandmother, and she practices folk remedies taught by her grandmother on Syaro, though she is skeptical about their effectiveness, which has also led her to enjoy horror movies. According to Syaro, her unique naming sense developed from a sense of crisis when she saw the Rabbit House menu as a child, and she is easily influenced by others, which leads her to suddenly change the café's or uniforms' atmosphere for a "Month of XX" under the influence of Cocoa or Rize.

She can row a boat at incredible speeds due to her strength, but her stamina is very low, causing her to collapse after intense physical activity or carrying heavy objects. She is lucky in dodging things thrown at her. Although not malicious, she has an unusual obsession with playing the fool, and once kept quiet until the straightforward Meg pointed out when she picked poisonous mushrooms.

In her second year of high school, she served on the festival committee with Cocoa, and her efforts were recognized with a nomination for the student council president election.

After graduating from high school, she aims to work at Ama Usa An while attending a university in a timber-framed town.
