Fate/Grand Order: Fujimaru Ritsuka wa Wakaranai - Dai Bounen Otanoshimikai 2023

Ritsuka Fujimaru—humanity's last master. It would not have been possible to restore humanity without him. However, he does have a shortcoming... he is far too honest! A slapstick comedy in which Fujimaru's simple questions sway the heroic spirits!
