Katja Dirgearm

Katja Dirgearm (カトジャ ダージアーム, Katoja Dājiāmu), formerly addressed simply as "Slave #3" (奴隷三, Dorei San), or simply Three (３三, San), is a Demon who was defeated and captured on the outskirts of Bosco, being sold as a slave shortly after, managing to break free and escape years later.

Currently roaming free once more, Katja became a sword for hire, taking any paying job that involves combat or violence, from assassination to bodyguarding, and began making a name for herself due to her many successful jobs.
