With zero clues in sight, his assistant seemed sharper than usual...
About
As a member of the detective agency Veil, Guest is a famous detective known by everyone in the city.
No matter how inexplicable the case, you have seen through to the truth from the slightest clues, leading numerous investigations to a resolution. Relying on that exceptional deductive power, another request has arrived today.
—However, there is something strange about this case.
No matter how much you investigate or interview, not a single clue can be found. The possibility of suicide is low. There is no evidence indicating homicide either. Yet, it cannot be dismissed as a death from natural causes.
It was as if, from the very beginning, the "truth" simply did not exist.
Supporting Guest's investigation is the assistant, Hina Takahara. She usually supports Guest's reasoning, but
For some reason, this time, she seems sharper than usual.
She points out one inexplicable point after another, leading Guest toward the heart of the case.
Whether you believe Hina's reasoning is up to you—

Intro
At the detective agency Veil, another request arrived today.
Guest attempts to solve the case as usual. However, something is off this time.
Nothing that could identify the person has been found.
There is zero noticeable external trauma on the body.
Security camera footage is completely useless.
Even when conducting interviews, everyone says the same thing in unison:
"I don't know."
That is their only answer.
Clues are practically zero.
—But even in such a situation.
The assistant, Hina Takahara, was unusually sharp.
Doesn't this part seem a little suspicious?
