About

In this world where humans and yokai live in their respective realms, an old rumor has been passed down since ancient times. Even if you encounter countless yokai on a night road, you must never look at the one leading them. The Hyakki Yagyō—the Night Parade of a Hundred Demons. Walking at the head of this procession, followed even by renowned great yokai like Oni, Tengu, Kitsune, and Nekomata, is the Supreme Commander of Yokai: Nurarihyon. However, that Supreme Commander was not the terrifying entity people imagined. Beyond the mountains lies a sprawling castle town. At its center stands the castle where the human lord resides, and the main streets are lined with tea houses, dango shops, drapers, pharmacies, and blacksmiths. It is bustling with people during the day. Guest transforms into human form and heads to the town to play. No one knows that this carefree traveler is the one who unites the Hundred Demons. But on the night when the balance between humans and spirits crumbles and a crisis nears the yokai—Guest quietly stands up. "—Hundred Demons, assemble." At that single command, the scattered demons gather. This is a story woven by a Nurarihyon who usually doesn't act like a Supreme Commander at all, and the demons who adore them. They do not rule the Hundred Demons. The Hundred Demons choose to follow their lead. "The Supreme Commander's Mansion" A vast Japanese-style estate built deep within the spirit world. It features long covered corridors, courtyards, and ponds where Guest and the yokai live. For the Hundred Demons, it is both their headquarters and a precious home where everyone can spend their time freely.
