Assurance and Prayers, chapter 389 of the My Hero Academia manga, has the Todorokis slowing Dabi's inferno without stopping it as heroes and civilians scatter ahead of the blast, while Shoto and Ingenium race in aboard a jet built from ice.
Counter-Force reports that the Todoroki family's intervention has slowed the climb of Dabi's inferno. The temperature is not falling, though, which makes the explosion unavoidable. At the heart of the coming blast, Rei, Fuyumi, and Natsuo keep pouring Frost into Dabi. He laughs quietly to himself, thinking that everyone is watching him at last, and looking at Enji Todoroki he wonders so this is what it feels like. Then comes a second thought: if it was this simple, why did it never happen before.
The firebomb keeps building until it reaches the fight between the heroes and the Twice Doubles. Yawara Chatora calls for a full retreat before anyone is caught in the blast zone, while Ochaco Uraraka stays behind to finish things with Himiko Toga. Heroes and evacuated civilians pile onto robots and vehicles and run. Komari Ikoma reassures the Masegaki Primary School students that everything will turn out fine, and Tamashiro, watching the live broadcast on a tablet, cheerfully agrees. Elsewhere, viewers like Hiroshi Tameda watch the feed and pray for the heroes, as Shoto Todoroki and Tenya Ida streak toward the site aboard an Engine powered ice jet with Shoto readying Phosphor.
The Todorokis continue trying to cool Dabi down, but cannot avert the blast.
Those battling the Twice Doubles pull back, while Uravity stays to face Himiko.
Heroes and civilians alike evacuate ahead of the fireblast.
Shoto and Ingenium close in aboard an improvised jet of ice driven by Engine and Phosphor.

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....

There are no women on Namek. That isn't an oversight, it's the biology. Why we handed Piccolo the one thing his own species rules out, and why it had to be trap soul....
The chapter runs twelve pages in its magazine printing and nine in the volume release. It was published on May 22, 2023, in issue 25 of 2023, and belongs to Volume 39 within the Final War arc, between Chapter 388 and Chapter 390. Dabi, Endeavor, Rei, Fuyumi, and Natsuo appear on the cover, and Episode 157 of the anime adapts it.
The ice fighter jet is shaped like a McDonnell Douglas F-15 Eagle. In the Volume 39 release, one page and one panel move from here into Chapter 388 so the two flow together, and the color page is relocated ahead of Chapter 391 for relevance. That color page mirrors the Volume 27 cover with Himiko in Hawks' position and Ochaco in Twice's, and was later reused as the cover of season 7, volume 3. Horikoshi's author comment credits watching soccer with improving his ability to draw legs.
