Victim

Victim is a Floor Guardian on the eighth floor of the Great Tomb of Nazarick. It has the appearance of 1 meter long bright pink embryo with an angelic halo and featherless stick-like wings.

Despite being one of the most rarely seen of the Floor Guardians, Victim is courteous to his colleagues. Victim speaks in a different language than the others NPCs, but though he speaks in an alien tongue, they nevertheless seem to have no trouble understanding him. He is humble and modest about his position as a living sacrifice, believing it is his sole duty and purpose to serve the Supreme Beings and Nazarick.

Victim did not exist in the web novel version.
