About This Demo

The First Light Novel-style Immersive Detective Game!

A mysterious girl suddenly visited your detective agency, offering to be your "unpaid assistant"!

And the sheriff's arrival brought a bizarre case.

A resident was found dead in his room, the doors and windows sealed shut.

The entire apartment, punctuated by a series of interlocking testimonies, has become a locked room, impenetrable to outsiders.

In this double-locked room, why did the deceased commit suicide? And was it truly suicide?

If it was murder, who is the murderer hiding among the neighbors?

An approachable merchant, a carefree unemployed, a naive actress, a intelligent salaryman. Who is lying?

Also, who is this girl, whose origins she can't even explain by herself?

The answers to these questions are up to you to uncover.

(The murder is among them. Perhaps?)

Say goodbye to rummaging through boxes! Experience a pure battle of wits!

"How Many Secrets Under Ceiling" is a deduction game that revolutionizes traditional mystery-solving by eliminating the need for physical evidence. Solving complex cases solely through logical reasoning within the text, exploiting contradictions and loopholes in conversation, and scrutinizing details and questions in narrative. This scenario is written by a new writer with Gentosha Mystery Fiction Award, based on The Walker on the Ceiling by Edogawa Ranpo.

Unmask lies, reveal truths, and become the sole master of this linguistic labyrinth!

In the game, you don't need to play the role of anyone else; simply be your authentic self.

You'll make choices based on your own logic, preferences, and even your personal values, solving puzzle after puzzle, navigating danger after danger, and having your every thought validated.

The Honkaku Mystery is written in the style of a light novel, making you always smile!

The lively dialogue and banter save you from all the unhappiness!
