I swear, this is legitimate story line! not fanservice! Promice!
If you have forgotten about the purple haze… remember way back when Sassy fed at the strip club… or the succubus did the fatal feeding at the Red Crux, or that time when Sassy went a little uhh crazy and killed that guy… the sexual energy was a purple haze… Fish gotta swim, birds gotta fly, succubus gotta… well feed.
Also good to know that Jinni fully supports Sassys career choice.
