Kanaya is a rogue Cuirizu from her original order, who’s defected to a Cuirizathi order calling itself the Lambent Blossom. By and large she is the only face most people can associate with this mysterious order of abominations, because she’s the one who’s been tasked with seeking out those who might suit the orders needs and inducting them. She’s also responsible for making clandestine deals between the order and those they’re seeking partnerships with.
Because she’s a Full cuirizu (by most people’s standards anyway), she escapes any suspicion of anything other than having gone rogue. Few ever hear of the order, and those who manage to only ever meet her. Only if negotiations go well, does anyone get to see more of the order after.
Negotiations themselves can become quite the process.
