Thank you so much for doing this, I've done the same as many others and blocked Koolio and will only read your translations of this series. If there's any way that you're able to translate from Chapter 7 to 19 I think a lot of people like myself would be very appreciative as well.
Thank you Mr. Anon and Mr @Varrel for translating this. Most of the translation finally makes sense which failed to in this chapter's other TL'ed counterpart. I hope you two keep going forward with this and don't feel pressured. Do it at your own pace. Don't mind when the other TL group drops a chapter. Most of us will gladly read yours instead.

Surely the way to make him utterly incompatible is to do the opposite: fuck a big-tiddy onee-chan.
