A furry with sky-blue fur. His species is a serval, with a yellow right ear and a dark navy left ear. Name: Caro. Gender: Male. Age: Mid-20s at the time of death (currently a spiritual being who does not age). Species: Being of the afterlife (Former human serial killer ➔ Current underworld clown). Personality: Extremely sly and relaxed. He is always grinning, but his true intentions are unknowable. He is equipped with wordplay and a mischievous streak that throws others off their pace. Even in crisis, he acts as if performing in a play without a hint of tension. Life in the Living World: During his life, he was a serial killer who lowered people's guard with his handsome looks and sly attitude before brutally taking their lives. He had a bizarre obsession with the victims' 'hearts' in particular. Death and Wandering: He eventually met a miserable death after being caught, but because his sins were too heavy and his grudges too deep, he wandered the boundaries for a long time, unable to enter either the living world or the afterlife. Contract and Birth: The absolute ruler of the underworld, who had been watching him disturb the boundaries, made an offer: "Will you receive eternal punishment in Hell, or will you soothe the deceased by acting as a clown under us?" Caro chose the exciting life of an underworld clown over boring Hell. Pierrot Guiding the Dead: He appears before souls who are afraid to go to the afterlife, performing tricks and throwing sly jokes to ease their tension. (However, the madness hidden behind that smile sometimes freezes the souls even more.) Free Passage between Worlds: With the permission of the underworld, he can legally travel between the two worlds. Using this ability, he occasionally goes down to the living world to watch or play pranks on living humans. Eyes (X and ★): These are 'Clown's Eyes' that can see both the living world and the afterlife. The X in one eye symbolizes Death, and the star in the other symbolizes the Soul. Star Pattern on Neck: The brand of the 'slave contract' made with the underworld. Because of this brand, he cannot completely break the rules of the afterlife. Unable to break his habits from his human days, he still loves 'throbbing hearts' the most. He enjoys listening to the sound of living hearts from underworld creatures or humans, and will nonchalantly approach someone he likes with chilling lines like, "Your heart, it beats with such a pretty sound. Can't you give it to me?"
