Is My Hero Academia You're Next Canon Novels & Stories

I get why this question trips people up — there’s a lot of crossover stuff floating around for 'My Hero Academia', and not all of it sits the same way in the official timeline.

From my perspective, most crossovers (those fun one-offs with other franchises, promotional sketches at events, or special game modes) aren’t considered canon to the main 'My Hero Academia' manga unless the creator, Kohei Horikoshi, or the official manga team explicitly says so. I treat those bits like bonus snacks: enjoyable, often interesting, but not something that rewrites the core story.

There are exceptions or gray areas: spin-offs that Horikoshi supervises or gives character input to—like 'My Hero Academia: Vigilantes'—tend to carry more weight with fans and can feel canon-adjacent. Meanwhile, gag manga like 'Smash!!' or crossover promos are clearly alternate-tones and don’t impact the main continuity. When in doubt, I check interviews, author notes, and official announcements; otherwise I enjoy crossovers as delightful extras that don’t complicate the main plot for me.

I’ve been deep into 'My Hero Academia' for years, and 'MHA More' is one of those spin-offs that fans debate about constantly. From what I’ve gathered, it’s not directly part of the main series canon, but it does expand on the universe in interesting ways. The stories in 'MHA More' focus on side characters and events that don’t clash with the main plot, making it more of a complementary piece rather than essential reading. The author hasn’t explicitly confirmed its canonicity, but the lack of contradictions with the main story gives it a semi-canon status. Some arcs feel like they could fit neatly into the main timeline, while others are clearly just fun extras.

What makes 'MHA More' worth discussing is how it fleshes out characters who don’t get much screen time in the original. For example, we get deeper backstories for Class 1-B students or pro heroes who only appear briefly in 'My Hero Academia'. The art style and tone match the main series closely, which adds to the feeling of authenticity. If you’re a completionist, you’ll probably enjoy it, but if you’re strictly following canon, you won’t miss anything critical by skipping it. The ambiguity around its status keeps fans engaged, though—some treat it as headcanon, others ignore it entirely.

I can confirm 'Adventures in My Hero Academia' isn't canon. It's a spin-off manga that explores fun alternate scenarios and gag-style humor, but it doesn't impact the main story's continuity. The characters are exaggerated for comedic effect—like All Might obsessed with taiyaki or Bakugo being overly dramatic about trivial things. While it's entertaining and captures their personalities in a lighthearted way, none of its events are referenced in Horikoshi's original work. That said, it's worth reading for fans who want more content between main arcs. It feels like a playful tribute rather than an expansion of the lore.
