Within the Rōran Ruins.
Kakashi led the way as the team captain, while Yamanaka Fū and Hyuga Hiashi, the team's two strongest sensory ninja, walked in the middle.
Asuma Sarutobi and Aburame Torune flanked them, protecting the two sensory ninja.
The reason Kakashi had been made captain of this team was simple.
He had been to Rōran on a mission before, and his captain back then had been Minato Namikaze.
At the time, he had encountered Naruto's team from the future.
But when Minato Namikaze used the Sealing on the Dragon Vein at the end, he sealed everyone's memories as well.
This second visit to Rōran Ancient City left Kakashi feeling how much things had changed.
Because... the last time he had come to Rōran Ancient City, plenty of magnificent buildings had still stood here.
Now, however, it had become an ancient ruin buried beneath windblown sand.
When they reached Rōran's core, Hyuga Hiashi, who was scanning the area with his Byakugan active, looked utterly stunned.
"This... just how vast is this chakra...?"
Through Hyuga Hiashi's Byakugan, a river of intensely colored chakra could be seen beneath Rōran's core, resembling a mighty dragon.
More importantly, deeper within this chakra dragon, countless branches extended in every direction.
"Kakashi, what is the Sealing Lord Fourth sent us to investigate?"
Hyuga Hiashi turned to Kakashi and asked, still shaken.
"It's the Dragon Vein's Sealing!" Kakashi then recounted his previous mission involving the Dragon Vein.
After hearing Kakashi's account, Yamanaka Fū frowned and asked, "So someone is trying to undo the Dragon Vein's Sealing?"
Kakashi nodded. "That's what Lord Fourth said, yes. That's why... he sent us to investigate and see whether the Sealing is still intact."
They successfully reached Rōran's core-the source of the Dragon Vein.
