V.2 - Ahnenerbe Kyoushikyoku
The crossover this time include Fate Extra, Fate/Kelaid Liner Prisma Illya and Fate/Zero.
2 Volumes (Complete)






This... This is one of the most hilarious, side-bursting, breath taking comedy I have read.
What would happen if you put all the Wars for the Grail and the Hunt for Vampires? A Cafe comedy that isn't like any. Tsukihime was the first VN I have played followed by the Fate Series. But take out all the serious stuff and you get this.
Wish they should just use this as the next Carnival Phantasm season. The Fate/Zero verse should be added as well...
10/10 PERFECTION!
