Vs. Queen Bee Arc

Running from chapter 19 through chapter 28 of My Hero Academia: Vigilantes, and adapted across episodes 10 to 13, this storyline sits between the Senpai Arc and the Osaka Incident Arc. It braids two plots with nothing in common until they slam together: a neighborhood music festival and a father's search for his missing child.

Kuin Hachisuka keeps seeding Naruhata with Trigger by way of her bees, and the drug keeps turning ordinary people into monsters. A new ally, Makoto Tsukauchi, gives Kazuho Haneyama and Koichi Haimawari direction by treating Kazuho's street act as a career. Knuckleduster stops circling the problem: he wants the girl behind the bee user's face, because she is his daughter Tamao Oguro.

Soga Kugisaki opens the arc canvassing a middle school with a photograph until staff run him off. A student lures him into an alley and empties a swarm of bees from under her skirt, and he survives only because Moyuru Tochi burns the swarm to ash. At a hospital, Iwao Oguro sits with his catatonic wife, brushes off the doctor's grim assessment, and promises he will handle Tamao himself. Soga brings him his break: a uniform and an alias that trace the bee user to a private school.

Kazuho's blog wins her an invitation to a live event, and nerves nearly talk her out of it. Makoto Tsukauchi steps in as de facto producer once Koichi carelessly outs her secret identity. The venue is the Marukane Department Store, rebuilding after Captain Celebrity's brawl with Ryuichi Gojiyama wrecked it, and Makoto trades equipment and staff for a credit line. Eleven performers assemble as the FeatherHATS. Kuin, reading a flyer that promises surprise heroes, decides a surprise villain is only fair, and unveils Teruo Unagisawa, now a gigantic eel.

Eraser Head, walking to an event he never wanted to attend, gets his excuse when Teruo lumbers into a crowded street. Erasure does nothing, because the eel body is not a transformation but simply what Teruo now is, and the creature slips loose on slime alone before loosing electricity that kills the power across the neighborhood. On a nearby roof, Knuckleduster switches on his Taser Knuckle, addresses Kuin as Tamao Oguro, and orders her home to her mother.

He swings without meaning to connect, since any real hit would cripple the body he wants back. Kuin answers with Bomb Bees, only the first genuine, then flees. He corners her in a dead end he steered her into; her bees dose her with Trigger, and the drug shakes her grip loose enough for Tamao's voice to surface. A second injection gives her borrowed electricity, and her claws stop his heart. She leaves believing him dead. He self-defibrillates, absorbs her final charge, and lands one clean strike. A pheromone canister bought through the broker Giran lures the swarm in to be destroyed. He plucks the Queen Bee from Tamao's ruined eye socket, then shocks his daughter's heart and starts CPR.

On the roof, the blackout leaves an anxious crowd and no MC. Koichi returns as The Crawler carrying Kazuho's microphone, and Pop☆Step explains the outage, organizes the glow-stick holders, and buys the crew half an hour. When the lights return, the FeatherHATS play their remix of the store jingle to a roaring crowd.

Detective Naomasa Tsukauchi picks up the Instant Villain investigation and notes how many civilians report insect stings. Eraser Head pushes back on the label for Teruo, who carried no injector, and mentions the bee he saw. Elsewhere a man in a police uniform snatches Kuin's last surviving insect out of the air in a blur and seals it in a capsule. Number 6 and his Overclock Quirk have entered the story.

Makoto stays on as the FeatherHATS' manager, and Kazuho's fan letters start arriving. Knuckleduster flattens a few absurd petty criminals, warns Koichi against assuming Trigger has left circulation, then declines an invitation back to the penthouse and walks into an alley. His mask and brass knuckles turn up there the next morning, left behind.

At the hospital, Tamao wakes, complains of a headache, and asks for her father. When she asks after her mother, Iwao thinks of the gurney in the corridor and the death that followed, and says merely that a visit is not possible right now, and that she has nothing to worry about, because he is here.
