The title translates to "A story where Eirin's breasts were teased until they grew into P-Cups".

Here's the original in case anyone wants to compare: http://e-hentai.fbk.tokyo/index/g/2550062/f3de4ead36/

Thank you for the fast translation. As much I like Diisuke a prequel wasn't needed, in my opinion.

@Aston9: I agree. As good as the art is in this one, it introduces some inconsistencies to the overall story of the P-cup Eirin series. I'm a stickler for stuff like that, even in eroge and ero-doujinshi.

A dude elsewhere mentioned that a Kaguya book would have probably been better, though I would have gone for a follow up to that Komachi/Eiki book from a while back. Or, even better, a Kanako book. I would make an actual effort to translate that if he were to make one.

PS: The one thing to note is that protag was apparently well on the way to karoshi (death from overwork), so he lucked out.

I agree with most opinions here. A Prequel wasn't required...

...However, what about an Onsen sequel? with all the Touhou girls with their new breast sizes now?

Enjoy this while you can, because it will be another 6 episodes of him fucking up the Urumi storyline with cuckshit.

@Moroboshi Yuumei Whomstve summoned me! But yeah, there’s a lot of minor inconsistencies that really destabilize the plot of the first and second book. We need a Kanako book after the upcoming Yukari book cause if it’s just another Eirin book, I’m losing interest unless we get Kaguya.

@Larequirem Yeah, we lucked out, bruh.

@hijikato He already did a rework to the Old Maid Alliance in a collection book (WILL THAT EVER GET TRANSLATED!!) but the other one prolly won’t since that’ll require a whole lotta character redesigns for the ones that didn’t get it. Though, it might be the upcoming Yukari one if I’m giving my best guess.

@fappychubb Diisuke has confirmed in the story and on his social medias, the Urumqi saga is done and he’d only continue it on his Fanbox in short pages. And thank goodness, since that leaves the door open for the rest of the cast.

I don’t get the need for a prequel. Why not just have a continuation, one that even shows us the status of the supposed quintuplets
