Three's a Wedding
In Kirigakure, there were rumours that the most closely followed romance in the village was about to be settled. The jounin sensei of one of the most successful genin in Kirigakure's history was going to marry her long time boyfriend, a chuunin medic nin working at the hospital. The exact details were only known to the few who would be there.
Kiyoshi was one of those. He is the Jinchuuriki of the Sanbi no Kyodaigame, and a member of the only genin team in Kiri to have completed an S-ranked mission. The details of the mission were highly classified, and the genin had had to recover from both serious injuries and severe chakra depletion, but the mission was a success.
Kiyoshi was fairly easy to recognise since he had a distinctive aura around him. Plants would burst into bloom if he stayed in one place for too long, making the citizens wonder if he was related to the Shodaime Hokage of Konoha. He had violet eyes with no pupils that seemed to almost look through you, and a strange birthmark that ran down from his left eye, an after effect of the sealing.
Not many people knew about the Sanbi, only his team, the Mizukage and his family. Because of this, he had grown up as a normal child, lacking the cruelty that most Jinchuuriki had to live with. He knew he'd been lucky, especially when he's been told about some of his predecessors' lives.
As the wedding march started up, his mood darkened. Everyone who knew about his curse, apart from his little brother Yuukimaru, treated him with a certain... wariness. Nothing too overt, just caution, like a potentially rabid dog that may turn on its owner with any sudden movements. He'd probably never have a wedding like this, considering what he held. All he could do is enjoy his friends' weddings and be content with that.
Still, today was a joyous occasion, not a time to be maudlin. His sensei was finally getting married; he had some time off from killing, and he could let his self control slip a little. The bride looked radiant, carrying rare mist orchids that Kiyoshi had convinced to bloom, and wearing a dress with small desert lilies embedded in it, again thanks to Kiyoshi. He owed his sensei a lot, and this was the best way he could think of to repay her.
The vows were exchanged quickly; being short and sweet, since drawing things out is a bad thing for a shinobi to do. As they kissed, the entire congregation joined in a round of applause apart from Kiyoshi. Kiyoshi was bent double coughing into his fist, unnoticed by everyone. When his fit subsided, his fist was covered in blood, which he quickly wiped away. There was another reason he suspected he would never be married; the seal holding the Sanbi had a fatal flaw, his body was slowly being broken down. It was a secret he had managed to keep from everyone, because he didn't want to see the looks in their eyes if he told them he'd be dead within two years. He didn't know if they'd pity him or be relieved, and he'd rather live without knowing.
Ignorance is bliss, after all.
There we go, another one down. I tried to show that if no-one knows about a Jinchuuriki, they might have a good life. Also I figure he died fairly young, so the wedding mentioned wouldn't be his own. I still don't own Naruto, so I can't make this canon.
