That's one of the reasons I thought her character was kinda fun was because she's such a nonchalant but mysteriously dangerous character. It's hinted that she could be from the Shadow Lands in her mini scene, and it's very possible I'll include a little more information about her or some small details in the next game ;D I had a few ideas that still could come to light but I can't reveal x3
That being said it's always possible that more scenes or story could be added in Chasing Tail too. I do still have some more planned updates, It's all just about getting to them and getting them done x3
