Why the magazine was used instead of the tankos?
There's a sudden change at page 131.

@boytitan
Makes sense, don't you think?
99% of the "bad" people in the Oysterverse ends well, so it's only logical that nothing bad happens with those two.
The one that died in the end, if some characters get's a "backstory" midway it's to show his "tragic" past and that he is one of the "victims", not one of the villains.

Something about the Oyster Extended Universe seems like it fits perfectly.

The characters are crazy and the chain of sorrow just compounds the misery and insanity every chapter. It might as well be considered snuff but,
no body is actually hurt (except the readers deep inside) so LONG MAY IT LIVE!!!!

... the Hentai not the rapists, those guys can repopulate and die in every chapter for all we care.

The teacher I remember but not the guy with ridiculous piercings, where was he from? Happy ending for those 2?

Base +6

@greed2
The guy is the kid who got his nuts crushed in Akutoku no Sakae grown up. I wonder if the big rapist's mom is from another work too.

Base +6, Korou +7

shame that the mag with his chapters doesnt seem to get posted anymore.
I've been dreaming of seeing this translated for the longest time https://e-hentai.org/g/1289135/2af3503993/?p=4

@Drworm301
Yup. I also want to see this one get translated. Shame that no one willing to do it. I only translated something that are more than 3 years old.

Base +8

Sorry, I’m just new here. Why when I click most of the gallery link above, it always says “This gallery has been removed or is unavailable”? Anyone know how to fix it?

Base +5

@xoxexhe
you need open through the other site. The EX one.
e-hentai block a few hardcore tag.

Base +8

At this point a work by Oyster reads like someone parodying Oyster. Some lines sound even more insane when read out of context.

Base +22, Toffu +6, Nonamewalker +6

@Drworm301, seagult

I'll probably translate it, using the Chinese scanlation (I read Chinese). Can't guarantee when though, since I'm currently working Hidefumi Akino's works.

Base +7

Thank you so much for translating this. Glad to know that Riko is still suffering

@seagult
You know any way to access the EX site? My account was created a quite long ago, but I still cannot access it for some reason.

Base +5

@rspencey776

I noticed that continuity as well! This stuff is crazy shit lmao... just as crazy as Maguro Teikoku (Tuna Empire)

Hopefully more of Oyster's works get fully translated so we'll finally figure out the whole extended universe thing!

Base +11

I plan to pick up unfinish translation of all Oyster older release like Shoujo Jigoku I-IV. But I don't know when I'm able to release. I'll be glad if someone could help.

Base +8

I need to throw my brain outside the window if i'm gonna read this.

Wow, this story makes no sense, but it sure was a good fap.

Page 105 was not translated. Can you do it? Thank you

@candrios
