Grand Assassin

is one of the seven Grand Servant classes. The Grand Assassin position used to be the only one that was limited to a single candidate, King Hassan, but after the events of the Babylonia Singularity the seat is now empty.Nasu and Takeuchi Q&A leak. 
Ordinarily, Tezcatlipoca would have been a Ruler or Berserker. This time, though, he is an Assassin, because First Hassan decided to step down from his post on their own circumstances. He has had to do it instead, because no one else can.Fate/Grand Order - Tezcatlipoca's Voice Lines
