水仙 / キンギョ, Kingyo

These three goldfish spirits are usually found flying about Satou. Their individual names are Suisen (red fish), Gyokuro (black fish), and Kiimun (yellow fish). As spirits, they seem young and immature, but they are capable of taking the form of children. They are curious and flighty in nature, but also blunt and even cruel. (Source: the manga habit)
