key visual

character visual

Yoshiki Tsujinaka (CV: Chiaki Kobayashi)

A high school student who lives in Kubitachi village. Accepting that his childhood friend “Hikari” has taken over “Nanika”, he lives with him while having conflicts. I like animals and insects.

Hikaru (CV: Shuichiro Umeda)

Half a year ago, “Nanica” appeared in place of the missing “light” in the mountains of the forbidden land, but the voice and appearance were similar but not the light. He looks innocent and curious.

introduction

In a certain village
We grew up together from an early age
Yoshiki and Hikari of the same age

The sun is shining
The voice of a bear cicada sticking to my ears
Ice cream on the way home

We laugh at each other for being trivial
One summer day that is the same as usual

“… you’re gonna be shining.”

Half a year ago, the light that went missing in the mountains
A week later I came back
Things that look like light in your voice and appearance
What was wriggling in it was

“There’s no light anymore…if you do that.”

Start walking with “Nanika” who looks like a friend,
“Unchanged” everyday life
But at the same time
A strange incident begins to hit the village

Falling into the unknown “Nanika”
The curtain of the youth horror story goes up now–
