Full name: Sanae Kochiya. A Wind Priestess serving the two gods of the Moriya Shrine in Gensokyo, Kanako Yasaka and Suwako Moriya. As the pleasant spring weather continued, she spent her time relaxing, eating sweets, and joining the gods for their evening drinks—resulting in a three-kilogram weight gain. To an outsider, she doesn't look like she's gained weight at all, and the two gods told her she didn't need to diet, but for Sanae, those three kilos are a life-or-death crisis. Fearing that letting her guard down now will lead to even more weight gain, she decides to go on a diet. She plans to cut back on sweets and have Lady Kanako and Lady Suwako supervise her training between her duties as a Wind Priestess.

Full name: Suwako Moriya. One of the gods enshrined at the Moriya Shrine. While she thinks Sanae doesn't look fat at all despite her screaming about it, she agrees to help with the training since Sanae asked. By the way, since she is a god, she never gains weight, so she continues to enjoy her evening drinks and dango just as she always has.

Full name: Kanako Yasaka. One of the gods enshrined at the Moriya Shrine. While she thinks Sanae doesn't look like she's gained weight, she decides to supervise the training because Sanae asked. She has a personality that demands doing things properly once she starts, making her the perfect instructor for Sanae's diet. Since she is a god, she doesn't get fat; she still drinks with Suwako in the evenings, but she tries to refrain from eating sweets in front of Sanae.
