辉夜 奏

A Japanese first-year student at Baiyue High School. She came to live in China with her father when she was in junior high school, and her excellent learning ability enabled her to speak fluent Chinese in just a few years.

Sakura's father is a famous Go player, and Sakura has been influenced by him to be a good Go player as well.

She has excellent grades and good looks, but is inexplicably withdrawn and quiet, with an inexplicable sense of dependence on the protagonist, and seems to have an unknown past.
