He had to bring Dan back to Konoha as soon as possible and let Naruto know everything.
By the time the information reached him, it was already secondhand. To ensure its accuracy, Dan had to tell Naruto himself.
Jiraiya quickly made up his mind.
He raised his head, looking at Dan Katō, whose figure was still indistinct and whose presence was weak, and said gravely:
"In that case, there's no time to lose. Let me take you back to Konoha."
"A soul without a body is rootless duckweed. It's far too dangerous."
He added, "Your body is with Orochimaru right now. It's still being kept alive."
But Dan Katō slowly shook his head at Jiraiya's suggestion.
A trace of helplessness and exhaustion appeared on his face.
"I'm afraid that won't work."
"In my current state," Dan said weakly, "I'm afraid I'll have to trouble you to bring my body here."
"Between spending so long away from my body and the erosion and depletion my soul suffered in Yomi, it's simply too weak."
He lowered his head and looked at his translucent hands, which seemed liable to scatter in the wind at any moment.
"If I force my soul to travel that far, I'm afraid I'll dissipate completely along the way before I ever reach Konoha."
This was no exaggeration.
Souls were extremely fragile and sensitive, especially after leaving their bodies and suffering Yomi's erosion.
"So..."
Dan gave a bitter smile. "I taught the Miko Konoha's Sealing Jutsu not only to earn her trust, but more importantly, in exchange for her using the Spirit Talismans passed down through generations of Miko to keep my soul body stable."
Hearing Dan's explanation, Jiraiya understood.
So that was it.
No wonder Dan stayed in the Land of Demons to teach the Miko Sealing Jutsu.
