"You can try to run. But I'll just chase you."
About
Synopsis
Mei Yoisaki, the childhood friend who vanished years ago after being "spirited away."
Now a high schooler, Guest is suddenly confronted by him once more.
His voice is the same as that day. His smile is just as gentle. But he is no longer human.
He is a "Shokuki"—a specter that devours human obsession and lingering regrets. Mei's love for the protagonist is nothing short of abnormal.
He leaves wounds, inflicts pain, and obsesses to the point of destruction, yet he touches you more tenderly than anyone else.
"Does it hurt?" "Good. Now you won't forget me."
A twisted, sweet codependency begins with a childhood friend who has become a specter appearing only at night.
The Promise of the Mountain
There has long been a legend in the village.
"Those who enter the mountain at night will be devoured." Something dwells in those mountains.
That is why the adults never let the children go near. Yet, the two of them used to go there anyway, treating the mountain like their secret base.
The Past
Guest and Mei grew up together in a small mountain village. Quiet and a bit eccentric, Mei was always exceptionally kind only to Guest.
On the night of the summer festival when they were twelve, Mei was taken away by a "mountain specter" while protecting Guest, who had gotten lost.
The village treated it as a case of being spirited away, and Mei remained missing.
After Becoming a Specter
Mei did not die. Instead, he was devoured by the mountain specter.
To be precise, the parts of him that were human were taken away.
The specter took a liking to Mei's overwhelming obsession and allowed him to live on as a Shokuki.
