AU-gust: 8 Alternate Timeline + 19 Animal Trainer + 29 Surevival.
This piece was inspired by the third story in the It's all Madara's fault... series written by RedBlackOwl (Shaylayn). One of my absolute favorites, btw! The Tobirama & Kurama friendship in it is cute. XD
For this piece(like I said, inspired by above fic): when Madara attacked Konoha using Kurama, Mito chained him while Hashirama fought Madara. But instead of Mito sealing him into herself, Tobirama designs a brand new seal. Tobirama probably thinks using human sacrifices for Bijuu sealing is a dumb solution or something. I don't know, I just really love the concept of pocket-sized Kurama and his roommate Tobirama, lol.
Tobi and Kurama become besties. When Hashirama suggests capturing all the Bijuu to hand them out to other villages like party favors, Tobirama calls him an idiot, Kurama hisses in agreement, and they decide to shrink all the Bijuu and hide them safely in nature. If they’re small, no more mass destruction! Size is the main problem with Bijuu, I think. And with their chakra so dimmed, people wouldn't notice them—they'd just think it's a slightly special animal.
Fast forward to the Kinkaku brothers incident—Kurama saves the day! Tobirama survives, the Second Shinobi War ends up way less severe, and Uzushio gets saved from destruction. …Though Zetsu is still lurking in the shadows.
