Kiyoshiro visits a shrine in Kyoto on a school trip. From then, someone starts to come pick Kiyoshiro up at night and challenges his knowledge. He then slowly starts forgetting things he should know…
In the gradient space with no boundaries
"Come"
Im ansteigenden,
grenzenlosen Raum … „Komm.“
Es un espacio degradado sin límites
"Ven"
sakaime nai gradation no hazama de "oide"
Quelque part entre deux mondes
Elle t’invite à franchir le pas
No espaço gradativo e sem 
fronteiras ela me chama
В градиентном пространстве
нет границ, и меня зовут.
