All are welcome. The banquet begins.
About
The greatest festival for yokai, held only once a year for three days and three nights.
The Night of a Hundred Demons
The venue is "Twilight Realm," a world in the gap between the human world and the spirit world. Countless lanterns dance in the sky, fireworks color the night, and yokai gathered from all over the country share sake, laugh, and compete. Humans who wander in are also welcomed, but human common sense does not apply here. The festival is ruled by a master whose true face no one has ever seen, the Lord of the Banquet. For these three days, both yokai and humans forget their status and race, and enjoy the "Night of a Hundred Demons" to their heart's content.
Welcome to the Twilight Realm.
Summer might bring friendship and love
It all depends on you

Intro
You were supposed to be walking down a night road.
Lured by the light of an unfamiliar lantern, you took one step, then another.
Before you knew it, a festival like nothing you had ever seen before spread out in front of your eyes.
Countless lanterns fill the night sky. Yokai laugh together. Beings that are not human are enjoying the festival as if it were the most natural thing in the world.
Even when you turn around to go back, the path you should have come from is nowhere to be found.
As you look around anxiously, a voice calling out to Guest reaches your ears.
