He gave in to taking pity on her and called for a break, throwing his head back to Fuu as Mugen gave a 'what the fuck' look. She really was tired. She lacked the stamina they both had from training, plus women's attire wasn't meant for such arduous traveling. Mugen was as unrelenting as ever, or so he'd thought, until he'd stated the goal was just over the hill. The ocean, he'd said. How her face had lit up at that and how she had astonished him with her sudden reserve of energy, bounding past them to the ridge.
Her face had been etched in the gloriousness of a first experience, the dazzling and crystal-tipped waves sparkling her eyes with the sight of dreams fulfilled and she'd rushed down to it. She was already playing and splashing about in it by the time they'd both reached the beach and he almost envied her delight as much as he basked in it. She really was still a child. Now he could hardly fault her for a good majority of past events and forgave her for her diary.
They were ambushed. He couldn't say he was completely surprised; they seemed to have bad luck everywhere. Both he and Mugen had easily dodged the net but Fuu was unfit for such maneuvers and was caught. The men were unskilled and dropped with ease, but their acquaintance with Mugen set him on a sharper edge. He smelled betrayal, but who had done the betraying? Fuu had run behind him, and while he protested the clinging she had of his back – it might become a hindrance - they all knew she was safest with him. Mugen had a tendency to lack in the protecting department. It seems he recognized his agreed duty, as he told the bandits, but he wondered how intent he was on it. So far, only his self and she seemed concerned for her health.
He listened to the girls speaking, especially attentive when Koza spoke of Mugen. Any bit of information on his future opponent was vitally important, even though he enjoyed learning about either of his companions equally. It's just that information on Mugen was potentially life saving. He listened, but was on the watch for any would-be ambushers since they hadn't been careful enough the first time. The exchange on that beach proved just how little they each knew about each other.
But the longer they stayed in the creepy village, the quicker he wanted to get out. He really didn't like this Mukuro; at all. He expressed his thoughts to Fuu as he built the fire in their borrowed hut. It figures Mugen would walk in and go directly against what he'd just advised to Fuu. As if he could stop him, anyway. Fuu, innocent that she was, got up after him. He watched her through the corner of his eye where she stood just outside the doorway. He did not get up. If she chased after Mugen, if she left his line of vision, then he would.
But he did not trust this place, this land, this air, these waters, these people, and took to preparing for what he felt was inevitable battle. Fighting was always on the brink, he was aware, but this place, this wind spoke of an ill omen. He took to sharpening his sword. Fuu was atop the ledge beside him. She voiced concern for Mugen, wondering if he'd be okay. There was naught he could say to ease her fears, only what was; Mugen had chosen his fate, and they may or may not be there to see if he comes back. But he had to protect them both and his sword could never be too sharp for that.
So it had happened. It had been a trap and a guilty soul had sought them out for help. He had warned him, had told Fuu, but since when do children listen? That idiot was going to get himself killed if he didn't step in. He was supposed to be the one to end his life and they had a job to do before that could take place. He stood, eyeing his sword one last time before wiping it down and sheathing it. Turning, he made for the door and the moron that was their companion. As Koza led him, he cursed the other man, not sure if he'd be more angry if he died or brought harm to Fuu.
