Succubus Connect

Yuina struggles with feelings for her non-biological brother and pervasive self-doubt. A mysterious voice leads her to an unfamiliar world, where she is immediately assaulted by a man. In that crisis, a succubus spirit takes possession of her form to intervene. This entity dispatches adversaries through sexual means, showing little regard for the physical or mental toll on Yuina. Her experiences now involve navigating this strange realm while linked to the wanton demon.
