Fate/Grand Order: Fujimaru Ritsuka wa Wakaranai

Ritsuka Fujimaru is humanity's last Master. Restoring humanity would have been impossible without him. However, even he has a shortcoming: he is honest to a fault! This FGO slapstick anime shows Fujimaru's naive questions throwing the Heroic Spirits into turmoil, and all in the original manga's surreal tone.
