Review Detail of AziaN in The Sinners' Queen

This novel is SO GOod! Great english and nice grammar! Though I was wondering what the mc's hair color is as it was not described in the first few chapters (maybe I missed it? I'm to lazy to scan the chapters for that) and I can't really use the cover as reference for the mc's appearance, as most of us will get a different picture from what we read (mine was Mirai Kuriyama from an anime called Kyoukai no Kanata, although with longer black hair. I pictured this character as the mc because of her shy and flustered nature, and glasses? I guess). P.S. Imagine the system as a yellow ball that has facial expressions (like an emoji) it made things a lot funnier for me.
