Thank you for liking my art! In terms of the character's backstory and design, it's about a twin sister who was exiled from her feudal kingdom that is under attack by an industrialized country across this ocean, and her family's tradition favors descendants that are skillful with a sword, but this one particular descendant is more skillful with the Rak' Massi, or the " Demon Moon" polearm weapon. You can piece this with my other work called "The Lone Journey." Again, thanks for the feedback! :3
