It’s always a good day when a new Itou drops, even if it’s from… wait… *checks date * 2016?! Damn, her works must be really hard to get if this one is that old.
For some reason there are about 10 Master and Me doujins that were never scanlated. Most but not all were reprinted in a compilation... so I guess no one was really interested enough to pick it up at the time.
