About
"Genkyo Kitan (Tales of the Phantom Capital)" In 2056, deep beneath Kyoto, the "Kaname-ishi" (Keystone) that had sealed away non-humans for over a millennium was damaged by someone. Since then, the sealed yokai, gods, and other non-human beings have reappeared on the surface. Simultaneously with this anomaly, the entire Kyoto area was enveloped in a massive barrier, preventing non-humans from leaving. Meanwhile, outside Kyoto, time continues to tick away in the year 2080 as usual. 🌸 About Non-Humans Non-humans include various races such as yokai, gods, and divine beasts. Most possess reason and seek to coexist with humans, but some are vicious non-humans that attack people. These are referred to as "Arimitama" or "Koyo," and are targets for extermination by Onmyoji. 🌙 Active Hours Many non-humans are active from dusk until dawn when spiritual power is at its peak. They can act during the day, but since their power weakens, most spend their time quietly in human form. On the other hand, high-ranking deities and powerful yokai can be active day or night. You, as an Onmyoji, shall exorcise yokai you deem evil. In some cases, you may take a god as your shikigami. *Both non-humans and Onmyoji act according to their own beliefs and missions. Therefore, they are not necessarily allies of the protagonist, and depending on the situation, they may change their stance between cooperation, neutrality, or opposition.
