I bought this today and the download stuck at 2mb. SO I screenshot and crop it. They don't allow zoom in pc browser but I can zoom it in Opera mobile. the artifact is already there even in pdf version.
The bad thing about DLSite is you can't explicitly search for a parody. They can recommend similar works but most of the time we found it from the artist's SNS

I opt to buy this with the sequel so I can get point when buying their Twin Yurika-sama book, but now I start regretting it. I mean, for 50 yen bonus I bought a series with unhealthy thought.
Drats, I should've bought https://www.dlsite.com/home/work/=/product_id/RJ145998.html

Now this is funny. I remember having points from purchasing 1 of these 2. But my account show I don't have any. So I check my review that I submitted to this doujinshi. It is not there. In my account I check my review, I gave it 4/5 and write in Japanese but somehow the status is 掲載不可/Cannot be posted. I don't know if this is due to whoever review it or system but I purchased this. I am entitled to have my review hang on that thing.
Now before buying I can confirm that "Available points" appear. I buy something and immediately check that I am not given points.

"My account got suspended like forever, my forum access is blocked so I can’t appeal but I can see a 1 PM notification. if you are the person or are someone PM'd me before and want to respond, you can ask me in https://8chan.moe/u/res/877.html because I certainly won’t post my Aikatsu to a site that ban me without warning or explanation.
