The Twin Brothers of the Furutani Family

The Furuya family has a pair of twin brothers.

Older brother Furuya Yu's diary: Graduated from the police academy today and successfully went undercover in the Public Security Bureau! (fist pump)

Younger brother Furuya Rei's diary: Graduated from the police academy today and successfully went undercover in the Organization! (fist pump)

Later...

Gin stared at the intelligence agent reporting to him respectfully and slowly exhaled a ring of smoke.

"I sent you to go undercover in the Public Security Bureau. How did they turn you around and send you back to spy on me?"

Furuya Rei: ???

Meanwhile, Furuya Yu stared at the rapidly increasing number of completed missions on his phone, deep in thought.

He's in the Public Security Bureau, so why are the Organization's completed mission counts going up so fast?!

P.S. No romance. The protagonists are the Furuya brothers, one with a black background and one with a white background.

Theme: Somewhere in this world, there is always someone who will make sure you never have to fight alone.
