Another demonic minion, with a very important story, is Jelyan. Jelyan is Kuro's twin sister, but unfortunately turned out to be the bad one.
JELYAN DOES NOT LOOK LIKE THIS ANYMORE. We will explore this further over the next few days.
This early version is ... I forget from when, probably 2004 or early 2005. You'll note her name on the sketch is "Jillian", not Jelyan. She was supposed to be a transformed human at that time, (another character's sister instead of Kuro's) but now she's of a different race altogether.
