Overview

About this game

■Overview

This work is a story-driven visual novel that places strong emphasis on cinematic presentation.

Alongside engaging visuals that keep players invested and a deep emotional immersion,

the game features tense battle scenes and full HD artwork that further enhance the player’s connection to the story.

The goal of this solo developer project is to deliver an experience that remains compelling from beginning to end—

to give players the feeling of “watching a full anime series unfold before their eyes.”

■STORY

“A story of atonement and coexistence between a young man burdened by sin and beings from another world.”

A university student living an ordinary yet empty life eventually learns that a choice he made in the past created a distortion in the world itself.

In order to repair the damage he caused, he begins a journey alongside beings that are not entirely human.

The Thin Line Between the Ordinary and the Unnatural

The story takes place in realistic locations across modern Japan—

a quiet town, shrines, a university campus, hotels, and everyday streets.

Yet behind this ordinary world, unseen forces are constantly at work:

restless spirits, forbidden magic, and mysterious entities moving in the shadows.

People simply fail to notice it.

Because the truth is—the world had already been broken from the very beginning.
