Minamino Shuuichi

Background
Kurama was not idle when sealed in his first two jinchūriki. The strongest of the Tailed Beasts had decades to plan a way to escape. Before being sealed by the Yondaime Hokage, the Nine-Tailed Fox created an agent that would act to free him from the seal using Creation of All Things. Despite being able to evade a four month campaign waged by Konoha's Sealing, Sensor, and Tracking Divisions, Shuuichi realized he would not be able to abduct young Uzumaki Naruto and release his creator, Shuuichi assumed the human identity of Minamino Shuuichi in order to fool a mindscan from Yamanaka Inoichi and become a Konoha ninja, claiming to be of Uzumaki descent and wanting to look after his "itoku-chan".

Personality
Shuuichi often describes himself as a nice guy, willing to forgive other people so long as they don't intentionally wrong him for the sake of making his life difficult.

Genjutsu
As Kurama was wary of Madara Uchicha's ability in genjutsu, the Kyuubi no Youko took special care that his agent would be well able to counter most Genjutsu, and transfered all the knowledge he had on the subject into Shuuichi.

Miscellaneous Knowledge
Kurama was able to give Shuuichi over four hundred years worth of knowledge.

Trivia
Minamino Shūichi is the human name of w:c:yuyuhakusho:Kurama in YuYu Hakusho.

 * (To Inuzuka Rimaru) "I assume by the prolonged silence that Mr. Great and Noble Stick-Up-His-Ass is throwing a hissy-fit about me preferring to talk to a trustworthy Inuzuka rather than someone with theiving eyes."
