Don't do this to me world... can't I have even a bit of happiness? I was like, FUCK YEAH KEI ARAI, then I looked at the uploader's name and the world came crashing down on me. Who the hell even scans this and on what? I can only imagine it being some sort of soviet machine relic from the 80s or 90s...
Didn't even address the possibility that the child could not be Koiwai's. I guess she was impregnated in part 2 by Koiwai, then. Anyway, nice work from Kansai Orange. I hope there's a continuation. I hope there are better scans, too, but I appreciate the upload.
