Obsidian

A troubled woman in her mid 20s who keeps to herself. "Obsidian" is not her real name but an alias. Rarely seen smiling. Survives on post apocalyptic Earth using a bloodstained nailbat as her weapon. Tends to be aggressive and ruthless in fights.

Obsidian's face is wounded and her hair, which she keeps in a long ponytail, is somewhat unkempt. She wears tattered clothes. Her trademark piece of clothing is a long and red tattered scarf.

A certain event leads to her losing her right eye, and she obtains an eyepatch later on.

Has a raven companion.
