Newbie Succubus "Loli Succubus; Lolisa"
About
When she first debuts, Lolisa is very timid and introverted, often worrying about her performance as a succubus compared to her colleagues. Despite this, she is hardworking, showcasing a willingness to improve herself via taking advice from and going on adventures with Dust to learn what constitutes a lewd dream. While she was initially naive and easily manipulated, she has become much more savvy about the world and more willing to trick and deceive others due to her time spent with Dust.
As with other low-class demons, Lolisa is infatuated by any higher-class demons; she is obsessed with Vanir and will do anything she can to spend more time with him or gain his favor.
