Wada drew her an NPC outfit as if she were a character for Fate/Extra. Re-used Hakuno's coat. And the School uniform colors, even the bowtie is there just shrunk down as a decal lol.
I don't hate it. I just think maybe Kronii's personal style clashes with Wada's preferences. Kronii tried to say she wanted something more tame and Wada just shat out a generic amalgamation of previous work.
