This is a palette cleanser for people who already live in Saki's world. The OVA strips away tournament pressure and just lets you watch these characters exist together, no stakes, no dramatic irony, just a family restaurant and a birthday and the specific way Ikeda's sisters drive her up a wall. If you've sat through the mind games and the supernatural tile reads, you already know why seeing them relax hits different.
A single OVA episode made up of four-panel gag skits, adapted from the Saki Biyori spinoff manga and starring characters from the first season of Saki. Two pros get together at a family restaurant. The captains of the four teams get ready for a joint training camp. Ikeda finds ways to entertain her younger sisters, the Tsuruga team ends up on a camping trip nobody planned, and Ryuumonbuchi marks Koromo's birthday. The episode came bundled with the limited first edition of the fourteenth volume of the Saki manga.
