Shibuya Incident Arc
On October 31, Haruta is in Shibuya and attacks Kiyotaka Ijichi on Uraume's orders. Uraume orders Haruta to patrol the screens outer perimeter and hunt anybody wearing a suit, which Haruta agrees to do. After patrolling for a while, Haruta encounters Nobara and Akari Nitta. Haruta is glad to see them since he is tired of attacking men in suits. As Akari goes to run away, Haruta faces off against Nobara. Haruta manages to figure out where Akari is and attacks her from a distance. After managing to wound Akari, Haruta turns his attention to Nobara and manages to stun her. Haruta then explains how Nobara is strong and that they don't live in a world where people win just by being strong, especially against his technique.

As Haruta wonders who to kill first, Nobara suddenly asks why he is doing this. Haruta replies that he is just doing things that are fun for him. He then stabs an unconscious Akari, while taunting Nobara's helplessness. As Nobara gets up, Haruta prepares to attack her but Kento Nanami shows up. As Nanami approaches them, Haruta tells Nanami that he has a hostage but notices that Akari has gotten away. As Nanami has gotten close enough, he asks Haruta where and how many his allies are. Haruta says that he doesn't know and attacks Nanami, only to be blocked. As Haruta notes his adversary's strength, Nanami asks the question again. Haruta repeats his answer, but Nanami interrupts him with a blow that sends Haruta flying into a wall. Stunned, Haruta notes that the blow would be fatal if it was not for his technique. Haruta thinks about how he has to get away, but Nanami catches him and asks a third time. Haruta denies any knowledge, earning another blow to the stomach. Haruta tries to attack Nanami with his hand-sword, but Nobara stops it, nailing it to the wall with a nail. Nanami asks if Haruta is responsible for killing the assistant managers, terrifying Haruta, who apologizes. After hearing this, Nanami sends Haruta flying into another building, knocking him out.

Later, Haruta wakes up and winds up coming across Megumi Fushiguro. Haruta manages to wound Megumi as he tries to get away. Haruta decides to follow Megumi, but doesn't attack him and just listens as Megumi explains how the Ten Shadows Technique works. Haruta suddenly figures out what Megumi is trying to do and tries to stop him, but Megumi is able to summon Eight-Handled Sword Divergent Sila Divine General Mahoraga. Haruta thinks about how he will have to face this shikigami with Megumi, but gets upset when Mahoraga knocks Megumi out. Mahoraga goes to attacks Haruta, but Sukuna shows up and saves him. Haruta tries to talk to Sukuna, but Sukuna tells him to shut up. Haruta then watches as Sukuna takes on Mahoraga. Haruta is shocked that Sukuna was able to defeat Mahoraga and stares at Sukuna. Sukuna doesn't like it and tells Haruta to leave, which Haruta does. Haruta thinks that it's one of his lucky days since he is able to live, but accidentally runs into Sukuna's domain and is killed.
