From the Nyaa description:
Source: R2 DVD Rip for OVA, R1 DVD Rip for movie. Dual Audio and Subbed. Denoised and filtered to clean up image and bring it up to standard to HDTV’s. This is v2 from my previous attempt. This time better denoising and less filtering was done. Minor color correction to remove yellow tint. The result is a crispier image while retaining more details than the previous version. See the results below. Original DVD source is seen at the left and restored to the right for each image.  The OVA includes all 3 Episodes/Rounds. The Movie version is the International Edition where they compiled all 3 episodes in one movie. The Movie version cut a lot of scenes from the OVA but added a music video at the beginning and a scene featuring Necrocaizer. So I did a “Fan Cut” of the whole thing where I spliced the missing scene from the Movie into the OVA and added the MV at the end after the credits. So the “Fan Cut” is the “complete version.” If you’re not interested in fan compilations just uncheck that one from the list in the torrent. HighL4 x264 crf=15 Dual Audio Subbed OVA
