So the Hachibi's sealing pot was the last treasure. Plus we get the secretary's name.Naruto 529
Naruto is training with bee. Naruto realizes the abnormality outside.
Word spreads in the HQ that Kinkaku has turned Bijuu. To suppress him, they need the last treasure. That thing (can't read the pot's name... something with "Amber (Kohaku)") is under Raikage's possession. The sacred treasure is sent to the battlefield using telepathy by Raikage's secretary.
Ino, Shikamaru, Chouji joins the battle. Chouji uses Nikudan-sensha on Kinkaku. Shikamaru uses Kagemane on him, but gets pulled because Kinkaku was too strong. Ino uses Shintenshin. Darui calls Kinkaku's name, to which Ino inside Kinkaku responds "YES!". Ino returns to her body. Kinkaku gets pulled into the pot.
Raikage's secretary's name is Mabui (meaning "bright" or "dazzling"... another pun). His jutsu is physical transportation of things at the speed of light.
