Selene

Into doubt, fear, and loneliness - Origin
Selene Astarte is a character that is quite mysterious, but has clearly been related to either parts of the completionism conflict, allegedly having a long-term relationship with Kuro, one that mayhaps may have given him this new "flirty" nature that he has shown around on recent events as of the early stages of Lucisfear Odyssey. It is also known that Tael trained her on maneuvering with a weapon to make sure she'd survive at Kuro's behest. It seems that Selene has not seen either of them in a long time however. There is not much more known about her.
