Disclaimer: Nope, not mine, and that's really a good thing.
The parkgoers who played as Yuzuriha Nekoi and Kusanagi Shiyu had never met in real life. Fairy Park was a big place, and always fairly crowded; perhaps the two had passed each other without realizing it, but that meant nothing. Both had their own family, friends, work, but they always found themselves coming back here.
Their partnership had started one fateful April. It had been night in Ohto Country, and a breeze blew the spring cherry petals through the air like snow. Yuzuriha's then-partner had been worse than useless; when the two had been confronted with their first oni, one girl had frozen while the other misstepped. Yuzuriha had looked up from catching her footing just in time for the oni to knock her gun from her hand. The weapon clattered to the pavement several yards away.
Naturally Inuki leapt to his mistress's defense, sinking his teeth into the huge black creature's limb, but he was only a dog, and a computer-generated one at that. There was only so much he could do. With a yelp, he was knocked aside. His girl dove for her handgun, but it was too late. The oni reached an enormous clawed hand for her.
Kusanagi arrived on the scene just then, and instantly leapt into the fray. His claw weapons made short work of the monster. Yuzuriha had immediately asked him to team up with her, and he had agreed.
They worked well together, once Yuzuriha got her focus. She took care of long-range attacks, and he handled the close combat. After a battle, the two would bask in the adrenaline and celebrate.
It started out as an affair of convenience – oni hunters were required to hunt in pairs – but Yuzuriha and Kusanagi quickly became friends, and then more. It was hard not to, really, when they worked so closely together. When exploring Ohto, they found all kinds of places that evoked the feeling of a date, and indeed they were dating. Yuzuriha enjoyed visiting cafes best, and Kusanagi liked the parks. Both liked each other. In Edonis, it would have been considered strange, wrong even, for a grown man and a teenager to be dating. Here, no one gave it a second thought, because no one actually looked like they did in Ohto Country.
In some ways, that seemed preferable. Since neither Yuzuriha nor Kusanagi knew what the other looked like, their relationship felt deeper and more important. It was a union between souls.
And if Kusanagi was really a slightly feminine teenage boy with wide green eyes, and Yuzuriha was actually the persona of an older man looking to pick up someone young and innocent, so what? Love could develop in those circumstances as well.
A/N: I had to go and make YuzuKusa creepy, didn't i? Well, maybe if there actually YuzuKusa fics in the Tsubasa archive this wouldn't have happened.
