Miko is a powerful hermit saint, who held the title of "Prince" Shoutoku in her past life, despite being female. These days, she lives in the Hall of Dreams' Great Mausoleum", a Taoist temple in "Senkai", a pocket dimension of Miko's own creation. Miko is extremely bottom-heavy, and her thighs, hips and butt are all immense.
Miko loves to eat, and to be fed.

She is in a bit of a rivaly with the buddhists under Byakuren Hijiri. Miko hopes to establish Taoism as the primary religion in Gensokyo.
