Which Characters Are Introduced In My Hero Academia Vigilantes Volume 1?

Eraser Head's frustration is palpable from his first panel. He's introduced as an obstacle, almost an antagonist to our heroes, which is a brilliant narrative choice that complicates the simple hero/vigilante binary.

I found the procedural aspects with Skycrawler and the police kinda boring at first, but they grew on me. They show the day-to-day machinery of hero society. How do you process a villain arrest? What's the protocol for quirk use in public during an emergency? How do heroes and police share jurisdiction? By introducing a pro hero like Skycrawler who is deeply embedded in that system, the manga educates the reader on its workings. It's not the most glamorous part of the story, but it's vital for understanding the constraints our vigilante protagonists are operating under. He's the embodiment of 'how things are supposed to work'.

You know, it's mostly Izuku and his two polar opposites: the destructive childhood friend and the constructive new mentor. Kacchan and All Might represent the two futures he could have had—one of bitterness, one of hope. Ochaco slides in at the end as the first peer who operates on All Might's wavelength of compassion. Nobody else in Class 1-A even appears. It's a very focused, almost claustrophobic start that makes the world feel huge when it finally opens up.

The spin-off 'My Hero Academia: Vigilante' introduces a fresh cast that operates in the shadows of the main series' hero society. The protagonist is Koichi Haimawari, aka 'The Crawler,' a quirkless guy who stumbles into vigilante work after developing a unique sliding ability. Unlike the flashy heroes of 'My Hero Academia,' Koichi’s journey feels grounded—he’s just a regular dude trying to do good, often clumsily, which makes him super relatable. His growth from a hesitant outsider to someone who genuinely cares about protecting others is one of the story’s highlights. Then there’s Kazuho Haneyama, better known as 'Pop Step,' a street performer with a bouncing quirk and a fiery personality. She’s the heart of the group, balancing Koichi’s nervous energy with her confidence and occasional recklessness. Their dynamic is a blast—part friendship, part will-they-won’t-they tension. The third key figure is Knuckleduster, a gruff, quirkless vigilante who mentors Koichi. This guy’s a mystery wrapped in leather gloves; his brutal methods and cryptic past add a darker edge to the story. The trio’s interactions—awkward, intense, or downright hilarious—give 'Vigilante' its distinctive flavor compared to the main series. Rounding out the roster are side characters like Makoto Tsukauchi, a detective with a moral gray area, and villains like Six, whose tragic backstory blurs the line between antagonist and victim. What I love about 'Vigilante' is how it fleshes out the everyday struggles of people outside UA’s spotlight. Koichi and friends aren’t destined for glory—they’re underdogs scraping by, and that’s what makes their fights and failures hit harder. It’s a grittier, more personal take on the 'My Hero Academia' world, and the characters’ raw humanity is what keeps me hooked.

It's a character piece first, a superhero story second. You could strip away the quirks and vigilante angle, and you'd still have a compelling story about three lonely people finding connection and purpose. Koichi is adrift, Pop Step is hiding her true self behind her idol persona, and Knuckleduster is haunted by his past. Volume 1 brings them together and shows how they fill the voids in each other's lives through this shared, illegal activity. The 'plot' is just the framework that allows their relationships to develop. The fights are exciting, but the real payoff is in the quiet moments: Koichi and Pop Step talking on a rooftop, Knuckleduster's rare moments of approval. That emotional core is what makes it special.

Honestly, my memory's a bit fuzzy on the exact chapter breaks. I think Book 1 covers the first few chapters? So it's Midoriya, Bakugo, All Might in both forms, the Sludge Villain, and Midoriya's mom. I don't believe any of the U.A. students like Uraraka or Iida show up until volume 2. Might be wrong, though. Someone feel free to correct me if the tankobon compilation is different.

Volume 2 is where the series' noir influences really shine through. Akaishi is your classic shady kingpin, operating in the shadows. The Instant Villains are the brutal, street-level consequences of his trade. Our heroes are the down-on-their-luck detectives (or vigilantes) caught in the middle. These new villains aren't just obstacles; they're genre signifiers, telling you exactly what kind of story you're in for—a gritty, street-level crime saga with superpowers.

He learns to integrate feedback instantly. Watch how he adjusts his techniques mid-fight based on what works and what doesn't. Earlier Koichi would stick to a plan until it failed completely. Now, he's fluid, adapting on the fly. This operational development shows a mind that's become expert in its craft. He's not just using his Quirk; he's conducting it, listening to the 'music' of the battle and improvising. That level of intuitive skill represents the highest stage of learning. It tells us he's moved from conscious practice to unconscious competence, which is the ultimate goal of any training arc.

Six lacks the personality of a Stain or a Shigaraki, and that's by design. It's not here to make a point or spread an ideology. It's a weapon, pure and simple. Its 'villainy' is its existence and its function. That makes it a very pure, uncomplicated obstacle, which the story needs at this point.

The concept of 'permanent injury' enters the stage in a real way. Up to this point, most fights ended with recovery. Mirio's eventual fate and the constant threat to Eri introduce a dynamic of irreversible cost. The heroes are operating in a space where winning might still come with a terrible, permanent price. This raises the stakes from 'we might lose' to 'even if we win, we could lose something forever,' changing the emotional calculus of every battle.
