Thanks to their great hint, I was able to get a better quality version of parts 3 and 4 (No watermark, 1080p)
Katsuki Ren - Myfans @KemonokaiNTR Part 3 (full version, 01h24m31s, 1080p)


H264, Bitrate 5542kbps, 3.27GB -

The H264 version of the player runs a bit heavy, so I am also uploading the AV01 re-encoding version.

P.S. Part 1 is Post 84 is best source quality.
Part 2 is Post 86 is not bad. I do have a slightly larger and heavier version... I will check if the quality is better and upload it additionally if necessary.
