In the past, she was once a knight who protected a kingdom and its people. Once defeated, her rapiers will raise around her and impale her as spade particle effects come out in the impact. She will continue breaching until the day ends or if she's suppressed. Her attacks take intervals to occur as she must stop to perform them. Once facing an employee, she will throw a homing rapier toward them, dealing Pale Damage (50), slowing them for a pair of seconds, and impaling them in the case they die. Like the other Magical Girls, The Knight of Despair possesses teleporting abilities to reach any room in the facility between some intervals. She possesses a average amount of HP at 800 and slow Movement Speed. If the blessed employee dies or panics, the state will be removed, the Abnormality will breach and her appearance will change - revealing black rapiers floating beside her, an eye open, and multiple spikes coming out from her body. The blessing remains until the end of the day and only one blessing is given at the same time.
The blessing halves all Red, White and Black Damage received, but 50% more Pale Damage and prevents the employee from performing any other work besides Suppression. The special state is marked with an icon above the affected employee. If this happens, she will create a blue veil around the employee before they leave the room, blessing the agent and giving them a special state. The Knight of Despair's ability will trigger when an employee first performs a Good work result.
