What does the tattoo on the banshee's belly mean?

The tattoo on the banshee's belly is a lewd tattoo.

The original birth of "erotic tattoo" seems to be impossible to verify, as if it had been printed in people's worst memories from the beginning. Generally speaking, succubus temptation and nightmare temptation belong to the inferno that absorbs human vitality. Orientals often confuse them with vampires. Vampires belong to the undead, also known as ghosts in the west. The demons and ghosts who live on human blood are all different races except these two races. Especially in some extremely sensitive parts, the embellishment of tattoos can always attract others' attention, thus releasing the charm of tattoo owners and showing their attractive charm. Later, in order to enrich the "depravity" setting of the character and create more internal and external contrasts by improving the concealment, the structure and position of the "erotic tattoo" gradually changed, and finally it became what everyone knows now-the lower abdomen below the navel was heart-shaped.
