What Came Was a Little Sister
Koto recalls her past training with her master and father, Inari, a shrine priest who often goes on missions. Late one night, Koto spots a black rabbit in her home and chases after it, coming across a room where she finds the paintings of the Mirror Capital and Lady Koto in her rabbit form, and Inari crying in his sleep while calling out to Lady Koto, deciding to keep it a secret. Back in the present, Yakushimaru, Yase and Kurama discuss the possible link between Koto and Lady Koto.

Kyousougiga
In Kyoto, nothing changes. No, not that Kyoto, but rather the Mirror Capital Kyoto, the world inside of a painting! Colorful, beautiful, but static, the people of this world live an idyllic, if boring life. That is, until Koto appears, like a wrecking ball slamming into still waters.
Koto's never met her mother, and in search of clues about her missing parent, she winds up in the very place she's supposed to be, yet least expected. What unfolds is a tale of a crazy, mixed-up family, where the father has mysterious powers, the mother is a goddess, and the siblings have an intense rivalry that will finally see its conclusion... even if that conclusion brings about the attention of the Shrine, an organization dedicated to protecting the multiverse.
