A suspenseful battle of supernatural powers that defies the truth of a closed world

The protagonist was killed by a man wearing a frog mask────

But in the next moment, he woke up in his own bed as if nothing had happened.

As he investigates, the protagonist gradually uncovers the secrets of his world—and of himself.

- - Additional Details --

This is a multi-ending visual novel set in a near-future city, where mysterious events unfold around impossible phenomena—things that grant people their deepest desires or supernatural powers.

Every choice you make carries consequences and affects your attributes, which in turn influence how each case concludes. You do not need to restart from the beginning to experience every route; once you complete a case, other routes become available. The full game is expected to take around 10 hours to complete all storylines.

To depict combat scenes, the game includes a simple click-based mini-game system. Combine cards you collect during the story or upgrade your abilities in the shop to gain the upper hand in battles. If you prefer to focus solely on the story, you can skip the mini-games via the settings.

Character Introduction

Miyoshi Yatsushiro:

The protagonist. Heir to a kendo dojo. He once dreamed of being killed by a man in a frog mask. One day, he awakens to a unique power—the ability to seal supernatural abilities into objects—and is drawn into a conflict with mysterious villains.

Frogman:

A villain who opposes the protagonist. He spreads Soma around the city and takes pleasure in the chaos it causes. He seems to have known Miyoshi for a long time and calls him “my hero,” constantly dragging him into new incidents.

Reiri Tachibana:

The protagonist’s junior disciple. After her mother fell into a coma due to a street slasher attack, she began living with Miyoshi. Cheerful despite her circumstances, she harbors deep hatred toward the slasher known as Kuro-Oni and is determined to uncover the truth.

Invisible:

A stalker who follows Reiri. Possessing the ability to turn invisible, he worships Reiri as if she were the sun. Mistakenly convinced that Miyoshi is the slasher Kuro-Oni, he targets him for assassination.

Cupio:

A chimera girl. Once an experimental animal that escaped from a research lab, she gained powers through Soma and took on human form. Though not human, she possesses strong desires and grows close to Miyoshi.

Masatoshi Shinohara:

An officer from the Public Security Bureau. After losing both arms in a terrorist attack, he developed a deep hatred for criminals. With powers granted by Soma, he seeks to eliminate evildoers by any means necessary.

Mimi:

A self-proclaimed deity visible only to Miyoshi. She has no physical form and suffers from amnesia. Her hobby is People-watching, and her favorite food is mizuyokan (sweet bean jelly).
