Sin

The leader of Real Kindness, a "squad" formed from criminal Nikkes in the Rehabilitation Center. Sin has the power to mind control people with her words. While it might seem like a certain other individual's ability to hypnotize and command, the dangerous part is that Sin's power is not restricted to Nikkes. She was captured and sent to the Rehabilitation Center for brainwashing people into her slaves, as well as inciting riots and anarchy. More than a few times, her counselors have been subverted and nearly sprung her loose before they were discovered and stopped. Even with the mask that stymies her powers, Sin's silver tongue makes every conversation a minefield.
