Arashi listened intently to what Itachi was saying. They were going to head into the Fourth Great Ninja War and at the moment they really weren't prepared for it. People were still trying to get over the whole Pain Invasion and if it hadn't been for the revival of the fallen shinobi then they'd be even more unprepared for this. He listened to the others speak and remained silent. They wanted to train, but he still had some training of his own that he had to get done. He felt like he was being selfish by not joining with them, but this was something he had to do alone. He couldn't risk the others holding him back or him holding himself back by joining them in their training. He wasn't sure they'd understand so he didn't plan on telling them the real reason why he wouldn't train.
Things started to heat up and Seth spoke against Izu and him calling out his abilities and saying he'd be the first to die with this slacking off attitude of his. Despite the way Izu said it he did have a pretty valid point. Being a drunk and a smoker all the time could prove to give you problems in battle and especially so at such a young age. It was probably why they had age restrictions for such vices. He walked with the others down the stairs and turned to Rin when she spoke to him. "Yeah... Everything's fine. I just have something I need to take care of at home. I might catch up with you all later."
He started running off and left the others in the mansion. As he ran towards home he wondered if his father would be able to stop this war. If he talked to Hashirama he could convince him that this war wasn't the best course of action, right? All he had to do was use that jutsu and this could all be over. If that was the case then why did Arashi still feel like he needed to train? Was he doubting his father or was it something else? He wasn't even entirely clear as to why he was doing this solo training. Did he want to become stronger on his own without others helping him? Did he feel constantly shadowed by others and wanted to make something of himself? All of these were possibilities and he felt like only time could tell what the true answer was. Because as it stands he had no idea himself.
