 * 3) In Konoha Kakashi becomes increasingly worried about the disappearances, despite the best attempts of Konoha, Kiri, and Kumo trying to solve the mystery. Kakashi suspects a genjutsu user was behind it and wants Sasuke to assist due to his Sharingan and Rinnegan being able to cast out genjutsu. Shizune, Sakura Haruno, Naruto and Sai come into his office to inform Kakashi that Sai has been in touch with Sasuke and there are no updates on the disappearances. Sakura reveals that she was doing some research and discovered that there have been other disappearances involving Konoha shinobi, including a regular patron of Ino Yamanaka's family named Tadaichi. They are alerted that intruders managed to get through the village's interior barriers at the gates and explosions are set off, causing massive fires. Naruto, sakura and Sai are joined with Shikamaru Nara, Choji Akimichi, and Ino, and they converse on what information they have on Tadaichi's disappearance and those in Kiri and Kumo. They find the Barrier Team ninja battling the intruders, and Ino recognizes one of them as Tadaichi. Sakura also recognizes the other intruders as the missing Konoha shinobi. Before they can engage in a fight, the intruders use an explosion to retreat and everyone suspects the missing shinobi were under a genjutsu. The missing shinobi explode due to the injuries received from Tadaichi's explosion. Aoba Yamashiro arrives to alert them that there are more intruders, revealed to be the missing Kiri and Kumo shinobi. Kiri evacuates its residents after learning of the situation in Konoha. In Kumo, Darui wants to bring Killer Bee for help but the Raikage refuses. As Naruto and the others battle the intruders, Naruto's wife, Hinata Uzumaki comes to their aid and uses her Byakugan to see if the opponents are under a genjutsu, which she says it is unlikely. They suspect that a different type of chakra is controlling the opponents and they can't injure them or else they will explode. Naruto uses Shadows clones to distract the opponents while Shikamaru uses his Shadow Imitation Jutsu and Hinata used her Gentle Fist to hit their chakra points and render them motionless. Aoba uses his sensory abilities to enter a Kiri shinobi's mind but is caught in a genjutsu trap, and Ino uses her Mind Body Switch Technique to save him, both passing out.
