Forbidden Words

Ay explains to Tsunade that Kinkaku and Ginkaku are two of the Hidden Cloud's most feared criminals, having nearly killed Tobirama when they attacked him during the peace conference with the Second Raikage. Ay also reveals the brothers use items belonging to the Sage of the Six Paths like the Bashosen war fan which utilizes all five Chakra natures, able to endure the items' use from ingesting some of the Nine Tails' chakra. Through Samui and Atsui assist Darui in fighting them, the brothers trap them in the Benihisago gourd through using a combo involving the Kokinjo rope that reveals one's spirit word and the Shichiseiken blade that curses it. Darui manages to change his spirit word when he almost got himself sealed, stealing the brothers' tools and trapping Ginkaku inside the Benihisago. But this provokes Kinkaku into entering his pseudo-Jinchuriki mode.
