"Between something and someone." U-chronia is a mysterious world constantly changing like a book whose pages are flipped out of order. You will wear the shoes of OU, the protagonist, to live through this game-shaped experience—without knowing what it really is.

The place is U-chronia, a hazy world that lives in hazy memories of the distant past.
OU, a young boy, wakes up in a dried up riverbed without any memories of his own.
He meets Zarry, an opossum with a flaming tail, who guides him on a journey to find out his story.
The Saudage Specter, who haunts the boy;
Gemini, who looks just like him;
The Weeping Woman "La Llorona", who leads him to tragedy.
All of them are there to change the Story and how it will end.
A pen-drawn world reminiscent of the illustrations in children's literature, accompanied by music for guitar and other instruments ripe with nostalgia for an old hometown.
This is the background where the Story, a story meant for someone, unfolds.
"OU" disguises itself as something else—an adventure game—to meet and interact with reality.
OU is also a challenge—a challenge to games as a whole.
