Going for a longer story. Hope nobody minds! It's going to be a KakuHida/HidaKaku and a little bit of SxD and KxI.
We Live in Different Worlds
Hidan was a criminal. A killer who, in all honesty, was brutal and merciless - but he had tactics. He didn't leave evidence, and he definitely did not leave witnesses. He could march into a police station unscathed due to nobody having any solid proof of his crimes. His white hair and his odd violet eyes distinguished him from anyone else. On his back, there was always a black coat with a high neck and white lining. And his scythe was kept under such a coat.
On the other hand, Kakuzu was the chief detective. He had an office to himself and was constantly trying to dig up evidence on Hidan's crimes, never managing to do anything. It irritated him that he had fought out so many times with criminals and had always won, but when it came to Hidan he was nowhere even close to capturing the one in question. Hidan had been questioned multiple times and seemed to know exactly what to say, when to say it and how. It was aggravating. Of all people, why was the young rebelling immature brat the one who could loosely escape his grip? All other criminals he had worked on were arrested, unless they paid him a big enough bribe.
He had no choice but to personally question Hidan.
Shuffling his sheets of paper together, Kakuzu sat across from the criminal, who looked him right in the eye. It was a bit freaky, but it was probably because of his strangely coloured eyes. Kakuzu smirked under his mask, wondering what the man in questioning would think of him without his mask. "Hidan. Did you murder the people of the Border Inn and place wooden skeletons into them?"
"No," Hidan answered, staring him straight in the eye. "It was not me."
"Did you blow up the bridge on the west side of the city at the day of the festival?" Kakuzu questioned. Hidan was suspected of these crimes, but he, himself knew these were not his.
"Not me," sighed Hidan, leaning back. He had recognised the man he was talking to from pictures in the police station, posters around town, flyers and websites detailing the 'great miracle detective'. So if he was a miracle detective surely he would know that wasn't his style.
"...Did you kill Anne Jane Pauper, aged twenty six?" Kakuzu asked. Hidan remembered nostalgically; the way she had screamed every time the three blades scraped across her skin. What a melodious sound.
Hidan... didn't want to leave just yet. He wanted to know more about 'Kakuzu the great miracle detective'. So, he wouldn't lie. "Yep."
