Warning: Ephebophilia.

Note: For those who are wondering about the title's meaning, it's based on the Japanese art site Pixiv's tag of Shizuo/Anri, commonly known as 罪と罰コンビ - roughly translating to "Crime and Punishment Combination." Other than that, another tag for these two is also known as 静杏 (roughly translating to "ShizuAn"), but I thought using the first tag as a title was far more interesting than the latter.

The first time she laid eyes on him, she thought that this was the man she shouldn't come across.

"IZAYA-KUN..."

What laid upon her was a man in a bartender suit, looking as ferocious as ever.

"Didn't I tell you to never set foot in Ikebukuro ever again, Izaya-kun?"

Prior to his sudden entrance, the bartender threw a trashcan at his victim. Miraculously, the victim got up with no signs of grievous harm, but he did show some signs of bruising and limping.

"Shizu-chan. Weren't you working at West Gate?"

The blonde bartender retorted the inquiry. "I got fired ages ago. And I told you not to call me that. My name is Shizuo Heiwajima."

"Shizuo."

Witnessing all of this, the bespectacled girl felt something within her, but it wasn't by her own admission.

The conversation between the bartender and his attempted victim continued. "Oh man, Shizu-chan, you still mad that I got you blamed for that thing?"

"I ain't mad. I just wanna kick your ass."

"Shizuo Heiwajima... is strong?" The girl shuddered by this new forth discovery, but not for the expected reasons.

"You know, your violence can't be stopped by words or reason, Shizu-chan. I'm no good with it. It's a real problem..." The bartender's victim - the informant Izaya Orihara - pulled out his switchblade. "Now let me go."

Seeing the informant cast his weapon at the bartender, the girl's trembling intensified. However, it wasn't that the sight of a man wielding a knife particularly terrified her. In fact, she wasn't concerned about him at all.

What did concern her was who he was coming up against.

"Violence... strong... he is strong?"

What was coming from Anri Sonohara's mind was not her own thoughts, but someone else's. Someone, or rather, something within her was waiting to come out. It was waiting to come out at the right moment, a moment where Anri wished she could have avoided it all...

And to her misfortune, a group of angry thugs suddenly appeared from the street's corner, carrying various weapons. They ran to enclose the heated situation, surrounding her, her friends, the informant, and the bartender all at once.

Anri did not like where this was going at all - not for herself, not for her friends, and not even for the bartender as well.

Just when it couldn't get any worse...

THWACK!

In a hysterical moment, one of the thugs frantically ran from behind and bashed his large stick at Shizuo's head. Anri gasped in horror upon seeing the bartender agonize from the blow, blood pouring from his head and into the ground. However, the agony turned out to be temporary, as Shizuo quickly regained composure and stood still in an oddly tranquil manner. Calmly, Shizuo addressed his attacker.

"You aimed for my head, didn't you?"

This can't be real, thought Anri.

"You do understand that, if you don't do it right, a blow to the head can kill you, right?"

He got up like it was nothing.

"You did it understanding that, meaning you wanted to kill me, right?"

This man is so powerful, he's someone not to be reckoned with.

"So, no matter what happens..."

So much strength, so much power...

"... you have no problem, right?!"

In a heartbeat, the thug found himself out of his clothes as he was flung high up into the air.

The moment Shizuo punched the thug across the street, Anri felt a sharp sensation.

"Strong, strong, he is strong, strong, strong, strong..."

The sensation was coming from Saika, Anri's hidden sword. Saika always had a love for humans, but none of them could either excite the blade so much, not like this man.

"I love him, I love him, I love him, I love him..."

The loud, relentless words overflowed Anri's mind, causing the girl to tremble more than she could handle. Anri always kept Saika under control with such ease. Now, it was loosening itself under her grip.

And it was all because of him.

The man who savagely attacked several thugs all at once. The man who threw a vending machine at his retreating enemy. The man who lunged at the tall Russian man when the latter intervened and caught the large object with his bare hands.

Anri cowered back, staring at the fearsome man. She had to get away from him, not only because of his temper, but because of what could have happened if she had stayed longer.

The more Shizuo lashed out, the more Saika screamed for his love. It was only a matter of time until Anri completely loses it.

Just when it was too much to bear, she was suddenly grabbed by her classmate Mikado and ran off. They ran as far as they could until Shizuo was no longer in their sight. Anri was grateful for Mikado to do this, since who knows what could have happened if Saika had gone any further?

As long as Anri stayed away from the most fearsome man of Ikebukuro, she was safe.

As long as Shizuo stayed away from the infectious parasite girl, he would be safe.

However, this wouldn't be the last time they would ever encounter one another.
