First of all, he was free to go. We were both standing up and neither of us looked injured. Second of all, it takes 2 to tango. He was a trained ninja. If he couldn't get out of the way of someone wandering slowly, he deserved to lose. Third of all, I did not like his attitude. "Forget the game. I'm going to get you back." he said as he got into a fighting stance. A pop-up appeared. "Clan Rival" was the name of the mission. I had accomplished the goal of a random event. I accepted it and he went hostile towards me. He wanted to beat me up over a silly game. That was fine with me. I'd knock some sense into him and get myself in the clan. He was actually pretty strong. Chihiro and I grappled up together a lot. It was only after the second time that I realized what he was up to. He was trying to get me hard. I had not idea what he was going to do when I did, so I knew to try and end the fight as soon as I could. Luckily for me, him attempting to use his kunoichi training was losing him the fist fight. I abandoned the grapples and submission holds. I was just punching and kicking him harder. Knees too.
Eventually, he fell to the ground spent. I decided to rub it in by grinding the sole of my foot into his belly. I was not doing it hard, so it was just annoying gloating instead of sadistic punishment. "How's that for a genuine apology from the heart, huh? I beat you fair and square, Chihiro. Don't start problems you can't solve like a baby." I said as I grinned down at him. He looked up at me with pure hatred. "I'll get you for this! Just you watch, Nagisa!!" he yelled to the heavens as I walked away from him. He was pretty strong and a chunin, but that was not a problem for me. I just needed to farm him this one time for clout. If he really wanted to keep challenging me to fight, he could try it all he wanted. Seeing as the armor plates were black and not a bright steel, he was from a side branch. Once I was in the clan, he'd just be made a giant laughingstock for always losing to me. I would probably have to be on the lookout for him though. I did not want to be killed or screwed over by Chihiro. That would make things very annoying for me. I would have to kill him at that point. Hopefully not though.
As I was walking away, I was called over by one of the elders. I wondered if he wanted to scold me for what I did. That would be a drag. I walked towards him and bowed deep. "Good day, Fumihito-sama." I said as respectfully as I could. Naruhito's younger brother was not a man to trifle with. None of the elders were. "Good job on that spar, Nagisa-kun." he congratulated. I smiled and thanked him. "You know Keisuke is a great help around the clan village and outside. It's even in his name. I'm sure you will be there at the wedding." he said. I nodded. "It's an honest honor to have him as a friend." He then put a hand on my shoulder. "You know. You've been just as much of a help to us as Keisuke. I think that you deserve a similar reward." he said seriously. This was it! I just nodded and let him say it. "You know, I have a granddaughter about your age. Genin kunoichi but has it in her head to reach all the way to Jonin." he proposed. "I would be honored to join your clan, Fumihito-sama. Even more so to join your family." I said. "I've already told her, and she's happy to meet you." he laughed.
