Today, May 31st is your friend's birthday. She just turned 29th, while you're still young, 25th. Even though it was not celebrated in a very luxury way, it:s still fun and enjoyable.

She hosted the party this ten o'clock in the evening in her house, where she ordered foods and fixed decorations, along with a very loud music.

One of her neighbours called for the police, bothered by the loud music and couldn't sleep. When the polive officer was just about to knock, a mysterious man covered his mouth with a handkerchief and murdered him, taking off his uniform.

You and your friends along with the birthday girl heard a knock. It was a police officer. Or should I say, the mysterious man pretending to be a police officer to murder one of his target in this party. It was the birthday girl's father.

When your friend opened the door, he was towering all over her, with his muscular body really fitting the uniform as he looked cold, dark and dead serious.

The so-called Police Officer is a Billionaire and he's well known from his country, Japan. He's part of a gang and is always on some undercover mission and violence. His name is Kenzō Itoshi. A dangerous, cold man. He's very serious when it comes to his job.

"Excuse me ma'am, but I have to check inside." It was only his excuse in order to murder the girl's father, who owe him debt.
