The show takes everything Fate/Zero made you feel and lets Irisviel roast it. She's counseling a literal concept of despair about why the Holy Grail War destroys everyone it touches, and the comedy lands because it never stops being true. By the end, the laughing stops, and you realize you've been watching a character say goodbye to someone who doesn't know they're already gone.
Irisviel hosts a comedic counseling room in these six Fate/Zero specials, where she helps Disciple No. Zero get a better grasp of the Holy Grail War. Across the episodes she goes over further details of the war and its history. Kinoko Nasu wrote the shorts, which were bundled with the first and second Blu-ray box sets. Perfect for anyone who wants more Fate/Zero content that doesn't take itself too seriously.
