I've Haven't seen the Christmas special cuz I've Haven't checked out the CG yet I'll do it later, but yeah thanks, and also is there a possibility of it? Since you said "currently" also the clothing system that actually want is for Ryen.
I like the idea of a clothing system, but it'd currently take too much time and effort for myself and the artist to implement it in a way that I'd be satisfied with. My focus right now is to finish the main story and started content, and I try not to add more work to my to-do list. But once all of that is done, I have the freedom to add every other idea again. Which'll probably keep me busy for several more years. :D
