The two men had found each other in a deserted part of Ikebukuro.
Shizuo took the cigarette out of his mouth and tossed it to the ground, crushing it with his foot.
Izaya slowly approached him, appearing unharmed.
"Shizuo, don't you think this game has gotten old by now?"
Shizuo's guard was raised, ready for whatever new trick Izaya had up his sleeve.
"You know, Shizuo, I'm the first to say the entire human race is something of a disappointment. But, I think you might be the exception."
Izaya placed a hand on Shizuo's chest.
"I think, maybe you and I could be a little more agreeable with one another. Maybe even be friends or… I suppose we could work it all out along the way. What do you say?"
Shizuo took a moment to think about Izaya's words.
Shizuo then took another moment to crush Izaya's skull between his head.
Izaya's headless corps fell to the ground before Shizuo, who was now covered in the man's blood.
"No." he said.
Shizuo spit on the lifeless body of Izaya Orihara and walked off to clean the blood off his barkeep outfit.
With Izaya dead, the world became a much better place, and no one missed him.
The End.
