Leviathan

The Morituri are a species of humanoids with canine and reptilian features that live in a society centered around bloodlust and ritual duals to the death. For each successful kill, a Mori adds a syllable to their name.

Leviathan kills with impunity and shamelessness, to the point where it prevents her from finding true companionship. The Mori equivalent of a hopeless romantic, everyone she meets is a potential sparring partner.
