When fans think about the moments that define My Hero Academia, large-scale battles and life-or-death internships often come to mind. Yet one of the most emotionally resonant chapters in the series arrives not with a clash of titans, but with a guitar riff, a clumsy dance routine, and a little girl’s first genuine smile. The U.A. School Festival Arc, which occupies chapters 172 through 183 of the original manga and episodes 81 to 86 of the fourth anime season, pulls back from the harrowing intensity of the Shie Hassaikai raid and delivers something quieter but just as powerful: a story about why heroes fight not just to save lives, but to bring joy.

This arc may lack the villainous masterplans of the League of Villains, but it compensates with character-driven storytelling, a deceptively layered antagonist, and the series’ central promise—that a true hero saves people physically and emotionally. Here, Izuku Midoriya and his classmates discover that making someone smile can be every bit as heroic as throwing a Detroit Smash. The festival becomes the backdrop for personal breakthroughs, the introduction of a memorable new foe, and the culmination of an arc of healing for a character who had only known suffering.

Setting the Stage: A School Healing After Tragedy

To understand the weight of the School Festival Arc, you have to remember what came before. U.A. High School’s first-year hero course students just endured the Shie Hassaikai raid, a bloody confrontation that left Sir Nighteye dead, Mirio Togata without a Quirk, and a traumatized child named Eri finally rescued from the clutches of Overhaul. The aftermath wasn't just about physical recovery. The entire hero community reeled from the revelation that the League of Villains could carry out such a large-scale operation, and class 1-A kids—barely a semester into their hero education—saw the grim side of their future careers up close.

The school festival was proposed by Principal Nezu as a way to restore normalcy and lift spirits. After the hero licensing exam, the work studies, and the raid, the students needed a break. But for class 1-A, and especially for Midoriya, simply “having fun” proved to be a challenge. They were still bearing the invisible weight of being the class that keeps getting attacked. The festival becomes an act of defiance—a way to tell the world, and themselves, that they can still smile.

The Festival Takes Shape: Class 1-A’s Concert Gamble

Instead of a standard haunted house or café, class 1-A decides to put on a live musical performance. The driving force comes from Kyoka Jiro, whose passion for music had always been a private comfort rather than a public talent. Her suggestion of a rock concert initially meets resistance—dancing and singing seem far removed from hero work—but the class rallies behind the idea largely because they recognize it as a chance to do something that’s purely about making people happy. This pivot from “impressive” to “joyful” is the arc’s first masterstroke. It’s not about showing off Quirks; it’s about connecting with an audience.

The planning phase is filled with the kind of genuine slice-of-life humor that My Hero Academia excels at. Bakugo is roped into playing the drums, and his explosive personality is channeled into surprisingly tight rhythm. Tokoyami’s brooding demeanor and Dark Shadow become an asset for the performance’s visual effects. Aoyama provides literal sparkle. Even Mineta contributes (grudgingly) without his usual antics. These scenes remind viewers that, beneath the costumes and Quirks, these are teenagers learning to collaborate and step outside their comfort zones. The support course, led by Mei Hatsume, crafts special equipment to make the show a spectacle, including floating speakers and automated lighting rigs that transform the gymnasium into a concert hall.

Meanwhile, the other classes dive into their own projects. Class 1-B’s play, a bizarre twist on Romeo and Juliet, exists mostly off-screen but sets up a friendly competitive spirit. The general studies, support, and business courses all contribute, making the festival feel like a living, breathing school event. This world-building is essential; it draws the audience into the school’s culture and reminds us that U.A. isn’t just a hero factory—it’s a place where young people grow.

The Gentle Criminal and La Brava: A Different Kind of Threat

While the students rehearse, a new duo begins snooping around the festival preparations. Gentle Criminal, a flamboyant self-styled villain with a tea obsession and a YouTuber’s hunger for fame, and his devoted partner La Brava, a hacker with a Quirk that amplifies her loved one’s power, plan to infiltrate the festival. Their goal isn’t mass destruction. They want to record a flashy trespass and upload it to the internet, cementing Gentle’s reputation as a notorious figure. To them, the festival is a stage, and class 1-A’s concert is just the grand finale they need to crash.

Gentle Criminal is a fascinating antagonist because he exists in the moral gray zone the series rarely explores in such nuance. His Quirk, Elasticity, lets him make any surface bouncy, and he uses it to pull off elaborate, non-violent stunts. He holds a grudge against hero society not because he’s evil, but because he was repeatedly failed by a system that values flashy Quirks and spotless records over good intentions. In his youth, he tried to save someone and messed up, leading to a criminal record that blocked him from being a hero. Now he acts out, seeking recognition. La Brava, abandoned by society herself, sees in him the validation she never got. Their relationship is genuinely touching; they’re partners who support each other against a world that rejected them.

This sets up a powerful parallel. Midoriya, too, was once a Quirkless boy told he couldn’t be a hero. But where Midoriya found All Might and a path forward, Gentle spiraled into petty notoriety. Their eventual clash is less about pummeling a monster and more about two people who understand what it’s like to be overlooked—yet made profoundly different choices.

The Rooftop Confrontation

Deku encounters Gentle and La Brava while patrolling the school grounds on the day of the festival. What starts as a tense conversation quickly escalates. Gentle, desperate to achieve his goal and prove he isn’t a failure, refuses to back down. La Brava activates her Quirk, Love, which boosts Gentle’s power to dangerous levels. The fight that follows is one of the most underrated skirmishes in the series.

Midoriya uses his newly developed Air Force Gloves, which allow him to fire concentrated bursts of One For All at range without breaking his fingers, and his Shoot Style footwork keeps him agile. The battle moves across the construction site near U.A., with Gentle using his Elasticity to turn steel beams into trampolines and projectiles. The choreography is a step above the usual punch-heavy exchanges; Gentle’s Quirk forces Deku to think creatively, bouncing off rebound surfaces and anticipating ricochet attacks. The cinematography in the anime adaptation, especially during the final exchange, where Deku uses a Delaware Smash Air Force blast while Gentle deflects with a Gently Sandwich, showcases the series’ kinetic animation at its best.

But what makes this fight memorable is its emotional core. Midoriya isn’t trying to defeat a monster; he’s protecting the festival for the sake of his classmates and for Eri, who might see her first real celebration. He pleads with Gentle, asking him to stop, and at one point even admits he can relate to the man’s frustration. When La Brava’s power activates, Gentle becomes a genuine threat, yet even as Deku lands the decisive blow, it’s handled with restraint. He punches Gentle with enough force to knock him out but not to maim—a conscious control of his power that reflects his growth beyond simply breaking his bones.

In the aftermath, Gentle is arrested, but he accepts it with a serene smile, finally at peace knowing that he fought for something wholeheartedly. La Brava, weeping, declares she’ll wait for him. The arc ends their story with a note of bittersweet redemption, underscoring the idea that even “villains” carry dreams worthy of sympathy.

The Concert: Eri Finally Smiles

With the threat neutralized, the festival proceeds. Class 1-A takes the stage, and the performance is a visual and auditory triumph. The song “Hero too,” an original piece composed for the anime, captures the arc’s theme perfectly: heroes aren’t just those who fight, but those who bring light to dark places. Jiro’s bass and vocals lead the charge, while Bakugo’s drumming and the class’s choreography generate an infectious energy. The animators packed the sequence with small character moments—Kirishima flexing, Kaminari being goofy, Sero swinging across the stage—that show the entire class united.

And then the camera finds Eri. Throughout the arc, she’s been shadowing Mirio and Midoriya, slowly learning what it means to be a normal child. But she’s never smiled. The concert changes that. The sight of her heroes—the same people who tore through the Shie Hassaikai’s fortress to save her—dancing and singing without a shred of menace triggers something deep inside her. A genuine, radiant smile spreads across her face, and Mirio, standing beside her, wells up with tears. It’s the moment he’s been waiting for since he lost his Quirk. Saving Eri wasn’t complete until she could be happy. Midoriya, spotting that smile from the stage, knows he won.

This scene is the emotional payoff of two arcs. The raid on the Shie Hassaikai rescued Eri physically, but the festival rescues her emotionally. It reinforces the series’ recurring motif: a hero’s job is never just punching the evil guy. It’s ensuring that the people they protect can find reasons to live again.

Character Growth Across the Board

Izuku Midoriya: The Hero Who Saves Hearts

For Midoriya, the festival represents a turning point in his understanding of All Might’s legacy. He has always idolized All Might as the Symbol of Peace—the hero who arrives and crushes evil. But after seeing Gentle and La Brava, and after striving to protect Eri’s smile, he internalizes a broader mission. He uses his new combat techniques not just to win, but to win without unnecessary pain. His conversation with Gentle before the fight, and his quiet resolution afterward, show a maturity that goes beyond raw power. He’s learning that being the greatest hero means seeing the humanity in everyone, even those who oppose him.

Kyoka Jiro: From Insecurity to Spotlight

Jiro’s arc is a triumph of self-acceptance. She never considered her musical talent relevant to heroism, even feeling embarrassed about it. By leading the concert, she reconciles her two identities and discovers that what makes her unique is exactly what makes her a great hero. Her confidence soars, and she becomes a more integrated, happy member of the class. The arc quietly argues that personal passions and hero work aren’t separate; they enrich each other.

Eri’s First Steps into the Light

Eri transitions from a symbol of suffering to a child beginning to believe in a future. Her interactions with the students, especially with Jiro’s music, help her discover things she likes. The smile isn’t just a cute moment; it’s the first time she exercises agency over her own happiness. It signals that she might eventually learn to control her terrifying Quirk not out of fear, but out of a desire to create joy like the festival did for her.

Gentle Criminal and La Brava: Sympathetic Shadows

Gentle and La Brava serve as a mirror to hero society’s failures. Their bond, rooted in mutual rejection by the world, is as genuine as any hero partnership. The arc doesn’t absolve them of their crimes, but it presents their story as a tragedy of wasted potential. Gentle’s final smile hints at a possible future redemption, and La Brava’s vow to wait suggests a loyalty that rivals the purest hero friendships. Their inclusion adds moral complexity to a story that could have been a simple feel-good episode.

Themes That Resonate

Throughout the arc, My Hero Academia revisits one of its core theses: a hero’s duty is to put people at ease. The concert isn’t a display of power but of vulnerability and shared joy. The festival acts as a healing ritual not just for Eri but for the whole student body. The repeated phrase “A hero should be able to make people smile” becomes tangible. The arc also explores the fluid boundary between hero and villain; Gentle might be a criminal, but his desire is born from the same yearning for recognition that drives many hero students. The difference is the support system each found.

Resilience emerges in quieter ways—not through enduring blows but through daring to be happy after trauma. The class 1-A kids, especially those who faced the League of Villains at the USJ, choose to create something joyful despite knowing danger could erupt at any moment. That courage is a quieter but no less significant form of heroism.

Legacy and Where to Watch

The U.A. School Festival Arc directly paves the way for the Pro Hero Arc and the subsequent dramatic shifts in the hero society rankings. The emotional groundwork laid here—particularly Eri’s development and Midoriya’s deepening philosophy—pays off in later conflicts. The arc also gave the anime one of its most iconic musical sequences, with “Hero too” becoming a fan favorite that embodies the series’ heart.

For those looking to experience this arc in full, the anime adaptation can be streamed on Crunchyroll (episodes 81–86 of season four). The manga chapters are collected in volume 19 and the beginning of volume 20, available through Viz Media. A detailed episode guide and community discussions can also be found on MyAnimeList.

In a series famous for earth-shattering punches and death-defying battles, the U.A. School Festival Arc stands as proof that the quietest victories can resonate the loudest. It reminded fans that a hero’s ultimate measure isn’t how many villains they defeat, but how many people they help smile—and that sometimes the best way to save someone is to invite them to a concert.
