What? 3 volumes? Wow we are gonna eat good
Why do you think it has 3 volumes? I just checked, there's only 2 on Amazon japan and the second one came out over 1,5 years agom so I doubt there will be more?
There is no 3rd volume. At least, that's what Baka-Updates says
Noooo :(
I think you guys are right. I thought there's volume 3 because I saw someone sharing vol. 1-3 in the YaoiOtaku forum
By the way, here's the link: https://www.yaoiotaku.com/forums/topic/124462-ryujin-sama-ni-oyomeiri-ikegami-shougo-jp/#comment-2636488
Since this has volume 3 I hope that annoying sister won't appear again.
