Who Are The Main Characters In My Hero Academia Vigilante?

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.
