Basically, how Genius Invocation TCG started and improved the relationships of many, many players. Contains Rosakae (Kaeya x Rosaria) Kazumiya (Kazuha x Yoimiya) Kokorou (Kokomi x Gorou) Cynari/Cynonari (Cyno x Tighnari) and a little bit of Beiguang (Beidou x Ningguang) on the side. Don't like a ship? Skip the chapter! They're all one shots, so no story connection.
