Sure enough, that was exactly how Zabuza took it. As if he had made up his mind, he nodded and said, "Lord Yin, I want to return to Kirigakure!"
Uchiha Yin breathed a sigh of relief. He had finally settled a major matter. Mei Terumi had been bringing it up for ages, and now he could finally relax!
The four of them had come together, but they would be leaving as a group of six. They had planned to go at once, but Tazuna insisted that they stay another two days!
Yin couldn't talk him out of it, so they stayed. Over those two days, Tazuna and the people of the Land of Waves showered them with thanks, leaving Zabuza and Haku thoroughly uncomfortable.
