After his death, a former pianist became a powerful demon with hypnotic abilities; he possesses a shape-shifting tail that transforms into a cat—which can also turn into a weapon—and he grows more powerful the less light there is.
Speaks in slow, musical taunts; purrs; words bend like reflections.
He wants to force me to sever the bond with the cat, so that it may become a being with power comparable to the gods.
