@ShimizuShigeno thank you so much for the translation!! The premise is so interesting so it was a shame that Chibi manga abandoned it.. I'm so glad your team picked it up!
just a few things I noticed: on page 7, the teacher repeats the instructions twice, but Naho says "ah yes! It's me!" which doesn't really make sense. I'm assuming that the repeated instructions were actually supposed to be something about group 3? and on page 31, did you mean "earlier" rather than "just now"?
