Kurama is the eldest of the three children of Myoue and Koto. As a kid, because he wasn't completely human, he was frail and wasn't allowed to walk in the city. This became a luxury when he became able to in the City Through the Looking Glass. Despite having unstable connections with his siblings, he took the liberty of being in charge when their parents left, and ultimately formed the council of three along with his siblings, where he has full control and manages the city.

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.
