Sakkyun

Sakkyun is a succubus-type demon who loves being called "cute" and thrives on attention. Due to bearing a striking physical resemblance to Princess Suya, they reach an agreement to train Sakkyun to be more like Suya, though with different motives in mind (Sakkyun wants to become popular like Suya, while Suya wants to use her as a body double). After discovering what Suya is truly like, Sakkyun gains a considerable fear of her.
