Since Shin Uchiha and his two teammates were heading out on a normal mission that involved no secrets, they followed the standard procedures.
All three arrived on time. Kakashi did not have the habit of showing up late as he did in the original story. After all, he was still in the Anbu, not a regular Shinobi with more freedom.
Their destination, the Land of Grass, was a small nation wedged between the Land of Fire and the Land of Earth. Being a small nation, it had no signature ninjutsu of its own and was pushed around at every turn.
Their objective this time was to bring Karin and her mother, members of the Uzumaki Clan who had ended up in Kusagakure in the Land of Grass, back to Konoha.
Time was tight, and Karin's mother's life could be in danger at any moment, so the three immediately picked up the pace once they left the village.
Kakashi was a veteran Shinobi, while Uzuki Yugao specialized in taijutsu and swordsmanship, so both had good stamina.
In the past, taijutsu had been Shin Uchiha's weakness, and he would definitely have held them back on this mission. But since he had begun practicing Lightning Release Armor, even its first stage had raised his taijutsu to the level of a jōnin.
That made the journey fairly easy for Shin Uchiha. Whenever he came across a place he liked, he could even use his Takamagahara dōjutsu to leave a space mark. Since all three wore Anbu masks, as long as he was careful, Kakashi and Uzuki Yugao would not notice that he had activated his Mangekyō Sharingan and was secretly marking locations.
With the mission so urgent, all three traveled at top speed, reaching Kusagakure in the Land of Grass in just three days.
