Kakashi's request to pursue Danzo and Root was rejected by Tsunade.
The reason was simple: Kakashi simply lacked the strength to pursue Danzo and Root. Kakashi could be considered elite among Jonin, but Danzo had already dominated the shinobi world more than twenty years ago. His strength was no less than the Third Hokage's.
Unless Jiraiya, the Hokage himself, personally led a team of more than ten Jonin in the pursuit.
But the village could not assemble a Jonin unit at the moment. If they chased them beyond the border, they might also be suspected of invading another country and provoking a war.
That was why most S-rank rogue ninja could roam free, with only wanted notices issued for them.
As for the possibility that the Masked Man was Obito, and that his own left eye might possess a Space-Time Dōjutsu, Kakashi did not report it. Instead, he had been researching how to awaken the Mangekyo.
He simply could not believe that his former friend had become a demon who attacked the village and caused the deaths of his teacher and teacher's wife.
He was more inclined to believe that someone had taken Obito's Sharingan... though that explanation was even more absurd than the Masked Man being Obito.
With nothing to do, Kakashi wandered the streets, glancing around at the Konoha villagers.
