(Umari senses an odd chakra in Rune.)
Umari: You're not a normal ninja are you?
Rune:

you know? I suppose you would. you're a sensor type after all.
Umari: That's it. I've heard of you. You're the Rokubi aren't you?
Rune:.....Yes I am the Rokubi Jinchuuriki Rune Temuri.
Umari: You're mother was the former Mizukage was she not?
Rune: Yes....those were some of the happiest days of my life, until the Iron Dawn came.
Umari: What happened that day?
Rune: When I was 8 I was kidnapped by Iron Dawn samurai. My mother and a squadron of ANBU tracked the Iron Dawn to a remote monastery between the borders of Amegakure and Sanro. The Samurai bested the ANBU and my mother stood against the 2 Samurai Beratan alone....my mom had the upper hand but in my desire to help her I became a liability. She died shielding me from one of the attacking samurai.
Umari....
Rune: Seeing her lifeless body just laying there.......I lost myself....The Rokubi's chakra enveloped me.. I killed both of those Samurai. The elders covered it up and told everyone that my mother had defeated them. The villagers hailed her as a hero. I was shunned and feared. No would take me in...Except for the 7 Swordsmen of the Hidden Mist. That trained me and taught me how to use a sword. Eventually I became one of them. And here I am.
Umari: So you have some control over the Rokubi? How much control?
Rune: Well....The Rokubi doesn't respond to a need but a desire. Whenever I am under duress, the Rokubi's chakra begins to poison my own.
Umari:.........Show me.
Rune: Uhm.....what?
Umari: The Yagyu sister desire power. They will come after you when they learn you're the Rokubi. If you hope to survive this, you're going to need to learn how to keep the Rokubi under control otherwise you're going to make a bad situation worse.
(Umari scowls at Rune. He walks up to him and glare at him intimidatingly.)
Umari: Let's get one thing straight, Rune. I don't like you. not because of who you are but because of what your are. I don't like Jinchuuriki. Bad blood you and your ilk. But I won't turn away your help. I need all the help I can get.
Rune:

You tell me you don't like me but expect me to help you?
Umari: It's nothing personal, Rune. I don't trust that thing in your stomach. Tailed beast are evil and if you can't control it then
I'd sooner rip it out of you!...
(Umari side kicks Rune out of the hidden area of the tallest tower and sends him plummeting to the ground below. Rune slams into the ground with a thunderous crash.)
Rune:
The hell's your problem, Umari?!
