Sakura Wars (2019 video game)

Sakura Wars, known in Japan as New Sakura Wars (新サクラ大戦 Shin Sakura Taisen), is a cross-genre video game developed and published by Sega for the PlayStation 4. The sixth mainline entry and a soft reboot of the Sakura Wars series, the game was released in 2019 in Asia and 2020 worldwide. The gameplay combines overlapping action role-playing, dating sim and visual novel elements.

The game takes place in a fictionalised version of the Taishō period in 1940, where the World Luxury Operatic Federation fights against those who threaten peace around the world. Naval captain Seijuro Kamiyama is transferred to Tokyo, where he must lead the struggling Imperial Combat Revue through a worldwide tournament of Combat Revues and fight the demons once again.

Chapter 7: A Flower's Fate
Just before the final match of the Combat Revue World Games, Elise and Margarete of the Berlin Combat Revue are attacked off-screen and appear for the match with demon's masks on.

The Combat Revue World Games are actually a trap for demons to destroy the world. As the Imperial Combat Revue fights through the twisted stadium structure, they are faced with the mind-controlled Elise and Margarethe, who are under the delusion that they are still in the tournament.

It was roughly adapted into Chapter 25 of the manga.
