Nasuverse/WMG

There is only one Anhenerbe cafe' in the whole of the Nasuverse
The door you use to leave it determines wheter you get to Kara no Kyoukai:'s Fumine, Tsukihime's Miyami, Fate/stay night's Fuyuki, the post-apocalyptic Angel Notes setting, or any other future Nasuverse location.
 * The only variation is whether the story is in its Main (dramatic) phase, or Expanded (less dramatic/silly) phase. Crossover characters (and Neco Arcs) stay away/out of sight in the former.
