Idk. I already watched the F/SN one but kinda curious with this one.
I find every episodes of it is kind of familiar, just noticed that everything inside of the F/SN:UBW is F/SN and the other fate series from google, oh well.
I finished f/sn in a long time ago, It's kind of nostalgia though, and it's nice.
Talk about fate series, well I kinda prefer the one with yuri and loli serial of fate. It's called fate kaleid liner or something.
