User blog comment:MiyamaSara/Have to do with the girl on Headmaster picture, Yume, Hime/@comment-3487190-20160814151009

I don't do much prediction, but there's really no knowing when this pic was taken. Perhaps this student came here when the current S4 girls haven't even come to primary school, or Moboroshi wasn't the principal in that time. So there are still other possibilities and we can't assume that this girl did have anything direct with Hime or Moboroshi.
