Somewhere in Tokyo—Fujimura.
The wail of police sirens echoes through the night-lit streets of the business district.
The man being arrested is Daichi Okuyama, the young president of a rising investment bank.
The charge? The murder of his wife and daughter.

In his solitary cell, he begins to piece things together.
“What the hell is this? I killed my wife and daughter?
Someone’s framing me… but who? And why?”

Then it hits him.
Just before his arrest, he was working on a major project—
investing in the development of a new drug to treat Type D influenza.
If successful, it would threaten the market dominance of the current treatment, “Tamivir.”
So, it had to be someone connected to Oogai Pharmaceuticals, the company behind Tamivir.

The masterminds are likely three people:
Takao Fujimura, president of Marcus Henry Investments, which funds Oogai Pharmaceuticals.
Hiroshi Kouno, director of Touyoko Science University Hospital and a co-developer of Tamivir.
Genzo Sasaki, a powerful politician who pushed for Tamivir’s approval.

“I’m pretty sure all three of them… have daughters.”
A wicked grin spreads across the man’s face.

“Heh heh heh… Fine.
I’ll make those bastards taste the same hell they put me through.
I’ll violate their daughters… and then kill them.”

Once released on bail, the man assumes a fake identity and infiltrates the gated community where the three daughters live.
His eyes burn with the fire of revenge…
