Kurusu Kotara

Kamira and Kurusu, as twins sometimes do in media, act similar to one another - playful, but also aggressive. Being succubi, the two of them feed off of sexual activity, and are more than willing to kill their prey when they've had their fill. All three of their sexual partners in Twin Succubus are killed in this manner. During sex, they will act submissive and defer to their male partners until it is time to finish up, during which they suck the life force out of their partners and kill them.
