Eika

"Now now, Shukaku-san. All I ask is that you don't be so antagonistic, you know? I understand what you've been through, really, I do. But it doesn't mean that you take out your anger on the world that does nothing more than fear and admire your power. Well, except for me. I like thinking of you as more of a companion rather than a chakra beast, because that's just inhumane, and I'm not inhumane."
