Constellation:

Character:

Although she is weak from the players' perspective, she is one of the strongest of her kind in Gensokyo. However, she is not very bright, and is a joke character second only to Meirin. Her hobby is freezing frogs and watching them revive as they thaw, but she tends to shatter them instead by accident. Unlike Letty Whiterock, she radiates cold air year-round, and can stay awake even in spring and summer.
