First of all, I appreciate you uploading some amazing Honkai Impact related art. It really helps since I don't really browse Pixiv myself and I like downloading it here in Danbooru because it saves me time renaming everything. Really makes organizing them a lot better.
Anyway, you've been tagging this outfit of Himeko as Vermillion Knight, which is wrong. That is the outfit for Blood Rose. So I took the opportunity of just changing them whenever I see you upload images of her. Just a little heads up.
