This story is about a mysterious figure that emerged from the shadows with an evil kokoro, roughly one year after the events of Mayonaka, set in 2014. While YTG will still lean towards shonen action like Mayonaka, it will also focus more on the relationships of the main characters, along with this universe's mystical and magical side. This will especially be the case regarding the Kami Neko, its Champion, and much more.

This series was initially planned to be an animated OVA, then as an audio drama, until finally as a fan comic/manga, to be told through mini chapters.
