垣花 彩楽

A first-year student at the school.
On the surface, she is a female student who belongs to the Marine Sports Club.

Behind her back, she is a member of the Ookumiza.
Like Shiiko, she is one of the shrine maidens (yuta) who serve the protagonist, Ichito, and is an aide to the king.
With the appropriate amount of dragon power (seji), Sairaku can freely control the wind.

Her personality is that of a modern schoolgirl.
She is a fun-loving, cheeky brat.
She hopes to leave this rural town one day and have more girly fun in the city.

By the way, Ichito calls the two of them "Shiisaa", combining Uiko's "shi" and Sairaku's "saa".
