Had them for a long time, but it seems it wasn't uploaded much after the demise of the original site which posted them. The nickname of one of the artists - "Ponya", another "Takara", others unknown. I think it is all based on the same story.
For real, I even tried commissioning Saha to translate it years ago. He took the job, but then gave me a refund telling me the copy I got from this gallery: /g/344701/b0eb0ae744/ had a too small resolution and he couldn't read the writing properly Almost 8 years later I've lost hope it'll ever be seen in English.
