Due to the weakened military power following the Konoha Crush, Team Guy (with Naruto filling in for the injured Rock Lee) was deployed to a weapon maker named Iō to retrieve a thousand shuriken and a thousand kunai. Instead of giving them the weapons, he showed them useless weapons he made. While out on a snack, Team Guy, under Tenten's command, returned to find Iō missing. They find out that he is hidden behind a wall with traps inside. Tenten managed to defeat all of the obstacles and she found a room full of Iō's greatest weapons. Meanwhile, two thugs, Gameru and Kusune, have come to take all of Iō's weapons. They are wielding Dakō and Tsurukame, two of Iō's prototype weapons, and with them they easily overpower Naruto's and Neji. However, Tenten was able to beat them using Iō's latest weapon, Jidanda. After the battle, Tenten asked to keep Jidanda, only to be refused by Iō, who wished to improve upon it.
Neji snaps Tenten out of her flashback as the two cross the bridge towards the research facility, with Tenten wondering whether Iō had perfected the Jidanda.
