The Hunt Begins

At Bang's dojo, the master casts out his battered pupil Charanko for failing to grow, and the boy later confides in Genos, who suspects Bang wanted him gone to keep him safe from Garou. Saitama, meanwhile, only envies how much cooler the name Silverfang sounds than Caped Baldy. Out in the streets, Garou announces his intention to hunt heroes, starting with Mumen Rider, when the Tank Topper Army arrives for revenge. Tanktop Master steps in and pounds Garou hard, but a horrified Mumen Rider takes his finishing punch to protect a human life. Feigning defeat, Garou then turns Bang's own Water Stream Rock Smashing Fist against Tanktop Master, brutally dismantles him along with the whole Tank Topper Army, and beats a trio of C-Class heroes who come searching for him.

Saitama visits the hospitalized Mumen Rider with bananas, where Tanktop Master explains that Garou wins by targeting weak points with precise technique rather than raw fury. Garou, meanwhile, borrows tactics from a lonely boy named Tareo's hero catalog, using its listed finishing moves to defeat the A-Class fighters Golden Ball and Spring Mustachio in an alley, then knocks out the sleazy Association worker Zeimeet. His rampage ends when Saitama, out searching for a wig, finds him and drops him unconscious with a casual chop before buying the wig for his Charanko disguise. After the credits, a worried Genos calls Dr. Kuseno about hair implants, only for Saitama to explain the wig is for the martial arts tournament he plans to enter.

Garou's hero hunt begins in earnest, taking down Tanktop Master, Golden Ball, and Spring Mustachio through superior technique. Tareo's hero catalog becomes his tool for targeting weak points, and Saitama unknowingly ends the spree while gathering a disguise for the upcoming Super Fight tournament.

Several anime additions frame the action, including Charanko witnessing Garou's clash with Mumen Rider from the park and flashbacks to the Deep Sea King and Melzargard while Tanktop Master describes Garou's anti-human fighting style. Garou responds to Golden Ball's taunt with a dislike hand sign rather than his middle finger, and his awakening in the trash the next morning was carried over to the following episode.
