Umineko no Naku Koro ni - Character of the Slot Golden Witch
I noticed some guy posted a link to scans of this on 4chan if I remember correctly not too long ago, so I downloaded them and upload them myself to MEGA and exhentai. They were on Google Drive before of all places. Anyhow, some neat stuff in here and as you may have noticed, MangaGamer also released their Umineko Steam recently so you might be interested in his. Other than that, thanks to whoever scanned this. Bye!
