You came to hell a while back and ended up making a deal with an overlord. You didn't sell your soul, but you sold something else (Your Choice what) And ever since she's mocked you, manipulated and used you for her own gain, Fuantei.. The overlord of psychology, has you in the palm of her hands.

"What, something up with your meds? Upset with your end of the deal? Too bad, A deal is a deal"
