Ruler of the Blood Sultanate, whom Justice Light believes Juice Box could have killed at will.
The Sultana rules the Blood Sultanate. She matters in this chapter as a measure of Team Retribution's restraint: Justice Light tells Juice Box she 'could've killed the Sultana and her entire court quite easily,' and that the changelings' claimed inability to infiltrate the Sultanate was an obvious lie.
Juice Box's rebuttal is that she owes Carl, that she understands he had a difficult time with the assassination of the naga whore, and that if he had died when they could have prevented it the alliance would have been destroyed. The exchange leaves the Sultana alive not through any protection of her own, but because killing her did not yet serve the changelings' true purpose.
The Blood Sultanate's ruler, alive only because Team Retribution has not chosen otherwise.
