Labinocle, a 22 years transgender man (someone who does not identifies with the sex assigned at birth), attends a unique art school called the School of Void. It is located in a mysterious but welcoming mansion lost in the nature where students can develop their own artistic identity. Labinocle befriends Natasha, Halloween, and Yann, other students, but hides his transidentity by presenting himself as a cisgender man (someone who identifies with the sex assigned at birth). From then on, Labinocle witnesses the appearance of a creature that constantly pierces him with its eerie gaze: the Tarasque. This creature torments Labinocle in nightmares. However, Natasha is there to offer advice like meditation to control his dreams. On top of that, Labinocle falls in love with another student named Balthazard. This unrequited love remains unanswered and ardently torments Labinocle's mind. Labinocle must face his identity questions at school and in his mind palace at the same time.
