This is a really interesting spin off concept. As a fate fan, there a lot of hits and misses in this family series but I am actually looking forward to see how this one plays out.
You see a lot of conglomeration, especially of character uses in this, that are easy to miss if you are not paying attention. I just finished re-watching apocrypha so it was fresh on my mind when I saw some pop outs in the background.
It is a school type series but more in like a Harry Potter way than a typical school type anime. The art style is good and the writing is alright. The episode was long but kept me entertained throughout.
