Jericho is an apprentice Holy Knight who served under the Weird Fangs. She was stationed at the Baste Dungeon, where the Deadly Sin, Ban was imprisoned. She is young woman of slim build, with light hair that is swept over the left side of her face and tied into a ponytail at the back. She wears a black coat over her armor, adorned with a cross on the left side and larger cross covering the back. Underneath her armor are similarly fashioned black clothes. Metal gauntlets cover her arms, while metal greaves and sabatons cover her legs and feet.
Jericho is a proud and serious individual. She is stern in her command over the guards of Baste Dungeon and overconfident in her abilities, appearing arrogant at times, which led to her humiliation by Ban.
