AEIL-185 - Rare footage: The legendary Lolita series that vanished

I see this 4-letter code manufacturer in stores often, but it's frustrating because if you rent 2 or 3 of their titles from the same period, there's a lot of overlapping footage. In that sense, I'm very grateful for the DMM sample images. From the 4th photo on, it's Itsuki Wakana, and photos 10 and 11 are Okano Miyu. I've seen this footage in other works by the same manufacturer. Since they edit their tapes differently depending on the project, I'd like to know the original source material. Can anyone tell me?
