We’re told Hisashi works overseas, breathing fire for some company. Seriously, that’s his quirk: fire-breathing, which is hilariously ironic given his son inherited absolutely nothing from him. He’s the human equivalent of a “be right back” note left on a counter—except he never comes back.
You’d think a fire-breathing dad would be a major plot point, like showing up to scare off a villain with a casual belch of flame. Nope. He’s so absent that fans have turned his non-existence into a running joke. Some theorize he’s actually All For One in a wig, which is both terrifying and a little bit ridiculous.
The “He’s Dead, Jim” Theory (But Also Not)
The most popular fan theory is that Hisashi Midoriya is dead, but not in a dramatic, tear-jerking way. More like he got a bad case of “plot-irrelevant-itis.” In the manga, Inko (Deku’s mom) never even brings him up after that first sentence. It’s like he vanished into a puff of smoke—literally, given his quirk.
Another, slightly more unhinged theory suggests he’s a secret villain. Imagine the reveal: Deku’s dad is the guy who runs the local ramen stand but also sells illegal quirks on the side. It’s the kind of twist that would make M. Night Shyamalan jealous, but it’s just a bit too soap-opera for MHA.
Here’s a surprising fact: Hisashi Midoriya is one of the most famous “missing” characters in anime history. He’s up there with Goku’s parents or Naruto’s dad—except those guys eventually got explained. Deku’s dad? He’s the whisper of a rumor, a ghost in the narrative machine.
