Ryu appeared in a swirl of leaves, in the Tengu's battle arena, his heart pounding. It glared at him, before flying up into the air, perching on a tree branch. He got into his fighting stance, and as the Tengu jumped down, hitting the ground just in front of him, he leant slightly closer to it.
"Let me take your life," he hissed.
"Who's talking," the Tengu responded, unleashing a barrage of punches, catching Ryu unaware. He fell to the ground after the first blow, partially because he had been winded from it, and partially because then he would avoid the other four or so blows which would have hit him if he hadn't. As he got up, the Tengu's foot came down, just missing him. He grabbed at it blindly, before launching into an Izuna, and jumping onto it shortly after it had hit the ground. It got up, turning away from him. He wondered briefly what it was doing, before it started stomping its feet against the ground. It turned around, and a giant gust of wind flew along the ground. The super ninja immediately blocked it, his arms taking the impact. Even so, bits of dust and dirt flicked mercilessly against him, having been churned up from the wind.
Ryu did a forward roll before seemingly doing it again. The Tengu moved forward, almost as if to grab him, except he lashed out with his feet as he did so, before coming back with a lightning fast 'Tenrin-Kyaku' which knocked the Tengu down again. As soon as it stood up, he grabbed hold of it easily before launching into another Izuna. It didn't move, after making the odd groaning noise for a few seconds it was still.
The fight was over, he had won, fulfilled his destiny. He jumped on it again for good measure before looking over at the pitiful figure sprawled at his feet.
"Farewell," he said softly, before turning away from it to stare at the sky. "Evil has vanished," he mused out aloud, contemplating what he would do now. What was there to do now, after all? He had fulfilled the promise to Hayate; he had no Irene to go back to, what else was he supposed to do? "There's no use staying here any longer," he surmised out aloud.
With that, the super ninja turned, before vanishing in a swirl of leaves.
Okay, this time I think I'll do three chapters because this one doesn't really count as a chapter, more like a paragraph. :| So, now we can find out what happens with Ryu and Ayane (if anything) and yeah, I drop the seriousness level a little from here. I've had to delete half of these ending chapters because they've turned downright funny instead of at least half serious and this was the best I could do ^^;
And a little note I put in a while ago, this story was completed before Tecmo announced that the new Ninja Gaiden was two years before DOA and that was when Hayabusa's clan was decimated, so in this story they still exist. Mmm, I guess you could say it did follow the storyline of the game until Tecmo decided to change the storyline…
