Yeah, I don't have much faith in Nutaku when it comes to games exported from DMM. Mist Train Girls has been around for over 2.5 years now and tends to be in the top three at least once per event when it comes to DMM/FANZA's popularity rankings. It's had multiple crossover/collaboration events (Walkure Romanze, Taimanin, qureate Games, Maitetsu, etc) as well.

Instead, the English version on Nutaku and Johren was consistently stingy with f2p content, had dodgy translations and typos, and didn't make it to the one-year anniversary before getting put on life support (started up August 30 2021, stopped updating July 1 2022, went into 'maintenance' March 31 this year).
