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.

GRIMOIRE - The Lost Ritual -』 Demo Now Available!
『GRIMOIRE - The Lost Ritual -』 Demo Now Available!Hello everyone! This is MURINGO, the developer of GRIMOIRE - The Lost Ritual -.Sorry for the late announcement, but the demo version of GRIMOIRE - The Lost Ritual - is now available!The demo is already playable, so if you've been curious about the game, we hope you'll take this opportunity to give it a try.■ A Demo Like an “Interactive PV”This demo is structured a little differently from a typical demo that lets you play through the beginning of the full game.Instead, it consists of fragments from various scenes throughout the story, with the events intentionally presented out of chronological order.Rather than following the story from beginning to end, the purpose of this demo is to let you experience:“What kind of game is GRIMOIRE - The Lost Ritual -?”You can get a taste of the game's world, characters, visual direction, music, and overall atmosphere.In that sense, you could think of it as an “interactive PV” that you experience by playing it yourself.■ Playtime: Approximately 30–40 MinutesThe demo takes approximately 30–40 minutes to complete.Although it is relatively short, we've packed it with various elements from the full game, including mystery, horror, battles, character interactions, and cinematic scenes.Music is also an important part of the game's presentation, and I personally compose the original BGM used throughout the game.Illustrations, visual direction, music, and story all come together to create the unique atmosphere of GRIMOIRE - The Lost Ritual -.We hope you'll experience it for yourself.■ About Full Voice ActingPlease note that the current demo does not include full voice acting.We originally planned to release the demo with voice acting, but unfortunately, due to our development schedule, we were unable to include it in time for this release.We sincerely apologize to everyone who was looking forward to the voices.Full voice acting is planned to be added during future development.Although this ...Read full article on Community Announcements (macimmortal66)Patch NotesOfficial
Development Update & Release Schedule
Development Update & Release ScheduleHello everyone, This is MURINGO, the developer of GRIMOIRE - The Lost Ritual -.Today, we would like to share an update regarding the game's chapter structure and our development schedule.Originally, the game was planned as a six-chapter visual novel. However, the development period has turned out to be shorter than originally expected, and our schedule has become increasingly tight.After reconsidering the overall development process, we have decided to change the structure to five chapters plus an epilogue.However, this does not mean that we are simply cutting content or shortening the story.The main storyline and important events will remain intact. Instead, we will make each chapter more substantial and improve the overall pacing, creating a more engaging experience that keeps players interested throughout the entire story.■ Winter Comic MarketAt the same time, we are also preparing for the Winter Comic Market.This time, we are planning to sell the completed full version of GRIMOIRE - The Lost Ritual - at the Winter Comic Market, rather than distributing a demo version.This means that, in addition to developing the main game, we also need to work on final adjustments, debugging, package production, printing, and various other preparations for the event.To be honest, it has become extremely difficult to keep up with our original development schedule.Nevertheless, we will continue working as hard as possible to deliver the completed game at the Winter Comic Market without compromising its quality.■ Release ScheduleAt this time, we are planning to sell the completed version at the Winter Comic Market.We are also planning to release the Steam version in 2026.However, since we are developing the Steam version while simultaneously preparing the completed game for the Winter Comic Market, the Steam release schedule may change depending on the progress of development.Rather than rushing the release, we want to make sure the game reache...Read full article on Community Announcements (macimmortal66)Patch NotesOfficial
