Everything's falling apart. That’s the feeling you get watching My Hero Academia Season 7 Episode 18. It isn't just another flashy battle sequence where people scream their move names and colors fill the screen, though we get plenty of that. Honestly, this episode, titled "It's a Small World," is more about the psychological crumbling of the Todoroki family and the sheer, desperate chaos of a world that has finally lost its tether to the "Symbol of Peace."
If you’ve been following the Final War Arc, you know the stakes. But this? This is different.
The Tragedy of the Todoroki Household in My Hero Academia Season 7 Episode 18
Dabi is a monster. Let's just say it. But he’s a monster Endeavor built, brick by flaming brick. In My Hero Academia Season 7 Episode 18, we see the literal heat of that resentment. Toya Todoroki isn't just trying to kill his father anymore; he's trying to become a nuclear event. He’s a ticking time bomb of phosphorus and hatred.
The animation here by Studio Bones shifts. It’s jagged. It’s ugly in the way it needs to be. You can almost feel the skin-searing temperature coming off the screen as Dabi’s body begins to disintegrate under the sheer force of his own Quirk. He’s literally burning his life force to make a point. It’s hard to watch. It’s supposed to be.
Most shonen anime treat power-ups as a triumph. Here, Toya’s "power-up" is a suicide note.
The episode does a brilliant job of weaving in the civilian perspective too. We see the regular people, the ones who aren't heroes or villains, just watching the sky turn orange. It’s a reminder that while Deku and Shigaraki are the main event, the collateral damage of the Todoroki legacy is what’s actually tearing the social fabric of Japan to shreds.

Why Phosphorus Changes Everything
The science—well, the "anime science"—behind Toya’s new technique is terrifying. By cooling his insides while amping up the external heat, he creates a thermal paradox. It’s what allowed him to survive this long, but in My Hero Academia Season 7 Episode 18, he hits the limit.
Endeavor's face says it all. Guilt. Total, paralyzing guilt. He isn't fighting a villain; he's fighting his greatest failure. This isn't a "Plus Ultra" moment. It’s a "what have I done" moment.
You’ve probably seen some fans complaining that the pacing feels fast. I get that. We’re rushing toward the finish line of Kohei Horikoshi’s epic. But the frantic speed actually works here. It mirrors the panic of the heroes. All Might is on the sidelines, powerless, watching his students and his former rival burn. The tension is thick enough to choke on.
The Toga and Ochaco Dilemma
While the Todorokis are literally melting down, we can’t forget the other emotional core of My Hero Academia Season 7 Episode 18. Ochaco Uraraka vs. Himiko Toga.
Toga is grieving. Twice is gone, and her world is smaller than it’s ever been. Ochaco isn't trying to just "subdue" her anymore. She's trying to understand her. It’s a radical shift in how we view heroics. Usually, the hero punches the bad guy until they stop moving. Ochaco is trying to reach out a hand to someone who wants to bite it off.

Is it naive? Maybe.
But that's the point of the whole series. The old way of doing things—locking people up and ignoring the "why"—is what led to this war. If Ochaco can’t reach Toga, then the heroes haven't actually won anything, even if Shigaraki falls.
The voice acting in this episode deserves a shout-out. Ayane Sakura (Ochaco) and Misato Fukuen (Toga) bring a raw, shaky quality to their dialogue. They aren't just reciting lines; they sound like two girls who are exhausted from a world that didn't have space for either of them to just be kids.
Some people think the "talk-no-jutsu" trope is overused. Those people are missing the nuance of what’s happening here. This isn't about talking someone out of being evil. It’s about acknowledging that the "villains" are victims of a rigid system. My Hero Academia Season 7 Episode 18 forces the audience to sit with that discomfort.
What This Means for the Finale
We are in the endgame. The chess pieces are almost all off the board.

- Dabi is a walking supernova.
- Endeavor is broken.
- Shoto is the only one who can possibly bridge the gap.
- Deku is still locked in a cosmic tug-of-war with Shigaraki.
The episode leaves us on a cliffhanger that feels like a gut punch. If you thought the previous seasons were dark, this is the abyss. The stakes aren't just "the world." The stakes are the souls of these characters.
One thing that really stood out to me was the use of silence. In the middle of the roaring flames, there are these beats of absolute quiet. It highlights the isolation of these characters. Even in a war involving thousands, the Todorokis are alone in their family tragedy. Toga is alone in her grief.
Actionable Next Steps for Fans
If you're reeling after watching My Hero Academia Season 7 Episode 18, here’s how to prep for what’s coming next:
- Rewatch the "Dabi's Dance" episode from Season 6. It provides the necessary context for the specific moves Toya is using now and makes the emotional payoff in the upcoming episodes much stronger.
- Read the Manga Chapters 387-390. If you can’t wait for next week, these chapters cover the immediate fallout of what we just saw. The art in the manga is significantly more detailed regarding the physical toll on Toya’s body.
- Track the "Todoroki Family" timeline. Go back and look at Rei Todoroki's role. Her involvement in the upcoming climax is pivotal and often overlooked by casual viewers.
- Pay attention to the soundtrack. Yuki Hayashi’s score in Season 7 uses specific motifs from earlier seasons but twists them into minor keys. Listening for the "Endeavor Theme" being distorted tells you everything you need to know about his mental state.
This isn't just a superhero show anymore. It’s a tragedy. And we are all just watching the fire spread.
