Jericho is a skilled swordswoman. She was able to move extremely fast and launch several slashes in an instant. After drinking a demon's blood, Jericho's abilities were greatly increased; she was able to defeat Ban with great ease, while he easily defeated her previously. In addition, Ban was mysteriously unable to regenerate from a wound caused by Jericho's attack, despite his regenerative abilities. King believe she could have the power to slow down time for the wound to heal or might be an illusion power that creates a sensation.
