The Second Daughter and Her Wonderful Monsters
It becomes the time of the year where the station opens and people send their unwanted things to float away. Later that night, a mischievious imp throws away all of Yase's crockery, sending her into a monstrous rage. After learning about the situation the next day, Koto, A, and Un search the station for Yase's favorite cup. During this time, Koto hears from Yase's butler how she once had her favorite doll thrown away because her brothers believed it could bring Lady Koto back. After failing to find Yase's cup after a day of searching, Koto tries to obtain Kurama's cup as a replacement, but this does not please Yase. She turns into a monster out of rage, but Koto manages to stop her. Seeing some of her mother in Koto, Yase gives her thanks for everyone's efforts and accepts the cup.
Aired 31/10/2013EP 4 - The Second Daughter and Her Wonderful Monsters

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.
