The Chase

Synopsis
At night, Koji Kashin infiltrates a Konoha archive facility and steals data. The next day, Team 5 and Team 10 discuss the event. Denki and Iwabee debate whether the theft was facilitated by the data being digital instead of on paper. Inojin comments on how the village's Barrier Team detected no foreign chakra signatures, leading Shikadai to consider an inside job. Chōchō wants to catch the intruder, and convinces her team-mates to help her. They find the tower where Koji was staying, and a computer with blueprints of the archive facility. Inojin spots someone nearby, who turns out to be Kakashi. He claims to be just walking around, but Shikadai deduces he's looking for the intruder as well, by himself instead of as a part of a group so as not to draw attention. They show Kakashi their discovery, and he suggests they continue investigating together, giving them earpieces. The four watch the tower, and spot Koji, but he switches directions midway to it. Inojin follows him from the sky on one of his drawings, but loses him in a crowd. Kakashi says the intruder noticed he'd been made, so he abandoned the hideout, and will try to leave the village. He considers the intruder went into the sewers to make it appear he vanished in the crowd. Knowing the intruder is dangerous from his moves and from the jōnin he took out in the archives, Kakashi goes after him alone, and instructs Team 10 to notify the jōnin on watch to seal the exists. Shikadai realises the intruder will leave the sewer not on the outskirts of the village, but on a Thunder Rail station. Kakashi is too far to make it in time, and Team 10 arrives as a train is leaving. Chōchō enlarges her arms and throws Shikadai and Inojin on the train. Shikadai paralyses Koji, but as Inojin gets close to unmask him, the shadow clone dissipates. Koji takes out guards and infiltrates another archive facility, but Kakashi arrived before him. After being contacted by Shikadai, he realised that Koji was trying to lure the extra security away by pretending to leave the village, so he could steal data archived on physical scrolls, yet to be digitised. Wanting to know how he slipped past the Sensing Barrier, Kakashi attacks him with Lightning Release: Purple Electricity, but it's a shadow clone again. Koji creates a smokescreen and escapes. He thinks to himself the data had nothing to do with his goal and wonders if he's getting sentimental. He's confused by the lack of a counterattack by Jigen to retrieve Kawaki, and realises his last fight took a lot of his chakra. Team 10 and Team 5 discuss the chase at Senju Park. Shikadai goes talk to Kakashi, and speculates that since the physical data was only from past shinobi, the intruder might be one of these past shinobi. Considering that, Kakashi adds that the intruder's chakra might be registered, explaining why the barrier detected no intrusions. Koji returns to Kara's headquarters and meets Amado. He informs Koji of Jigen's condition, and that all other Inners are away. They mean for Koji to kill Jigen.
