Chapter 9

Deku vs. Kacchan (デクvsかっちゃん, Deku bāsasu Kacchan) is the ninth chapter of Kōhei Horikoshi's Boku no Hero Academia.

Summary
Katsuki, now enraged, is contacted by Tenya, but Katsuki tells him to keep guarding the core and then cuts him off. Katsuki attacks Izuku again. Izuku tells Ochako to go on without him which she does. Izuku responds to Katsuki by using the Capturing Tape on his leg, but Katsuki breaks free using an explosive right swing, which Izuku manages to dodge thanks to his analysis on Katsuki's fighting style. Knowing his opponent is powerful, Izuku retreats to think of a strategy, much to Katsuki's anger. While Katsuki is walking to find Izuku, he reminiscences about the past; about how he was superior to everyone else and that Izuku was just a Quirkless loser as well as remembering about how Izuku tried to help him out after he fell, which just angers Katsuki even further.

Meanwhile, Ochako has reached the room where the Nuclear Core is with Tenya guarding it. Ochako decides to stay hidden and wait for Izuku. However, Tenya manages to spot Ochako after she gives away her location when she giggles from Tenya's villain performance. Tenya says that he prepared for Ochako's arrival and gave the floor a thorough cleaning, preventing her from tricking him.

Izuku, still hiding from Katsuki, contacts Ochako and asks her where she is, to which she replies that she is on the middle room on the fifth floor. Katsuki eventually finds Izuku, questioning him on why he won't use his Quirk. Katsuki says that his Hero Costume has bracers that can store sweat which is what he uses to create Explosions. Now that it has stored up enough sweat, Katsuki's pulls the bracer and unleashes a huge explosion which destroys a great portion of the building they are in. Izuku manages to survive and calls Katsuki insane. Katsuki, seething in rage, demands that Izuku use his Quirk.
