Honestly I don’t know from what game or anime character this is. It could also probably be an original paper craft made by raven.
A succubus is a Lilin-demon in female form, or supernatural entity in folklore (traced back to medieval legend), that appears in dreams and takes the form of a woman in order to seduce men, usually through sexual activity.
The male counterpart is the incubus. Religious traditions hold that repeated sexual activity with a succubus may result in the deterioration of health or mental state, or even death.
I fought a lot of Succubus in Ragnarok Online game. That was a fun time…
Anyway this model requires 6 sheets of paper to build.
