In "The Curtain Rises! The New Combat Revue", the train chase in Petrograd, the Flower Division singing "Star Tanjo!" and Sakura using the "Divine Blade: Cherry Blossom Blizzard" attack towards the end of episode 1.
Anastasia barely gets any time in the spotlight compared to the other returning Imperial Combat Revue members. Sakura and Hatsuho get an episode together, as do Claris and Azami, while Anastasia never gets A Day in the Limelight like them.
Xiaolong and Yui only appear on a few occasions despite being recurring characters in the game while also being stationed in Tokyo, making their absence even more bizarre.
Xiaolong and Arthur don't show up for the Final Battle with no explanation given even though Yui and Lancelot are there to help out the Imperial Combat Revue.
