Excellent! I will soon share re-synced Nyoro~n subs for these. Or you can get the pack from Kitsunekko and adjust them by -500 milliseconds, works for at least EP1 perfectly. Don't bother with SSP-Group subs, I think they are the icky official ones from US DVD, Nyoro~n's are way better.

There's not that much difference between the R1 subs (via Anime-Eternal) and Nyoro~n's. For instance, is "Yeah, she's the Mermaid Clan princess" (R1) staggeringly worse than "Yeah, she's the daughter of the queen of the Mermaid clan" (Nyoro~n)? It wouldn't surprise me if Nyoro~n's script were just an R1 edit, rather than an original translation.

At least it doesn't have the multi color look of the R1 subs, which look bad.
