Umineko no Naku Koro ni - Stage of the Golden Witch - Episode 4 EVE [DVDRip][480p]

Exact provenance unknown, but it is likely a DVDRip that was re-encoded, potentially multiple times.

Go support the Shingidan Yumeinochi Classics stage group (by buying access to the broadcast on confetti or ordering a DVD or smth), they did an amazing job with this adaptation!
