About this game

Pursue the truth hidden in the darkness of Shinjuku.

A noir visual novel featuring a former detective and a genius hacker.

■ Story

Three years ago—a detective lost his life in an underground passage in Shinjuku.

The death of his partner, Endo. The investigation closed, unsolved.

Former detective Saeki Ren's time had stopped since that day he lost everything.

One night, a young genius hacker, Rin, brings him an urban legend.

"Every week, a blue rose appears in the underground passage that was supposed to be sealed off."

It was the very place where Endo collapsed.

The blue rose—its flower language is "impossible."

That single rose begins to set in motion the frozen three years.

The dark underbelly of the giant IT corporation "Xeno Systems."

A traitor lurking within the police force.

And the "key" held by Kasumi, the woman he once loved.

The truth is built upon someone's lies.

What awaits beyond uncovering all the gray areas?
