It has been awhile since we saw Yuri (if you're not counting the R18 verison) & felt Kisa sensei was acknowledging her existence. That being said she kinda deserves it for being a cheeky brat. Thanks for the translations.
Yuri is a good character for the story. I don't generally prefer jealous characters scheming against others, but the way she was instantly dominated by Satou back then was such a funny scene. In a twisted way she even accepted getting closer to him, totally against her own will, as made evident by how she just normally answered to Satou's personal and friendly greeting, not realising anything was off before reading the group chat messages.
