Orime

About
Gluttonous by nature, Orime is a ninja with two mouths and four eyes (the mouth being at the back of her head and the additional eyes on her shoulder blades). During their first sexual intercourse, Rance has the mouth at the back of her head open and try to eat him, though he successfully managed to stop it. From that point on, they only had sex in the missionary position. Seen as a divine spirit by certain individuals, Orime took advantage of this to take some food offerings in Oda.
