The second season of 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! The FGO slapstick anime once again shows Fujimaru's naive questions throwing the Heroic Spirits into turmoil!
