I finally got the chance to watch Carnival Phantasm, which is quite the treat for Type-Moon fans.
It brings together characters from Fate/stay night, Tsukihime, and Melty Blood and puts them in all kinds of different situations that parody various aspects of their respective series. For example, the first episode has the Holy Grail War from Fate/stay night in the form of a game show.
As to be expected, it helps if you are already familiar with the characters since the parodies make sense and are actually amusing when you know their individual personalities. However, the scenes can feel pretty random at times, but I guess it gets so ridiculous that it becomes funny.
The series consists of 12 OVA episodes that are each around 14 minutes long, so there’s plenty more coming!
