Fate/Zero: Onegai! Einzbern Soudanshitsu

Inside the Einzbern consultation room, Irisviel takes on the unlikely role of counselor while her bewildered pupil, Disciple No. Zero, tries to make sense of the Fourth Holy Grail War. Questions about Masters, Servants, command spells, past conflicts, and the Grail's complicated history become lessons delivered with far less solemnity than the war itself deserves.

As familiar participants drift through the room, their tragedies and mistakes are examined from an unexpectedly playful angle. The result is a strange refuge where the rules and history behind a lethal ritual can finally be discussed without another battle breaking out.
