The Deadly Art of "Education": Why Reze’s Lessons Were Never About Love

Hey, it's Ren.

An empty classroom after school. Still, shimmering water. Reze teaching Denji how to swim, sharing bits of school life—it all feels so innocent, almost sweet. But if you saw that scene as mere "romantic progress," then you haven't truly grasped the horror of this story.

Hidden within those gentle ripples of water was a profound, calculated intent to kill.

"Education" as a Calculated Method of Weapon Training

Reze’s "lessons" for Denji—the talks about school, the swimming instructions—were far from just a playful side of her character. They were a brutal form of training, a way to neutralize her target.

If you look closely at her behavior throughout the Reze arc, she is essentially teaching Denji a "normalcy" he has never known. The concept of school, culture, the mechanics of swimming—to the reader, these look like romantic advances meant to bridge the distance between them. But underneath, the narrative follows the exact same rhythm as combat training.

The author masterfully weaves the "lessons of love" with the "acquisition of combat skills," running them in parallel. Every moment where the reader feels their bond deepening actually functions as a countdown to their destruction. This structure—where progress and ruin are two sides of the same coin—is nothing short of genius.

The "development" we felt as readers was actually the very foreshadowing used to lure the prey into the trap.

Exploiting Denji’s "Hunger"

What is it that drives Denji to listen to Reze’s every word?

He simply wants a "normal life." For him, even the smallest, simplest joys—like eating toast with jam—felt like a distant, unattainable dream. That is why the "poison" Reze offers, disguised as school life and new knowledge, is so incredibly intoxicating.

Denji’s reaction is pure and, ultimately, defenseless. He doesn't resist what she teaches him; instead, he hungrily clings to this "new world" she presents. This very eagerness to learn becomes the opening that leads to his downfall.

Reze knows Denji’s hunger intimately. She knows exactly what he craves and what he lacks. By positioning herself as a teacher, she systematically strips away his defensive instincts. As the student, Denji grows emotionally dependent on her, never realizing he is being led into a trap.

"Education," in this context, is the most silent and effective form of attack.

The Cruel Truth: Both are Merely Tools

By the end of the arc, we are forced to face a devastating reality: both Reze and Denji are nothing more than tools for their respective organizations. Reze is an assassin sent from the Soviet Union; Denji is the vessel for the uncontrollable Chainsaw Devil. They are both weapons, forged specifically to destroy one another.

The "swimming lessons" and "school knowledge" were perhaps the only way they could briefly pretend to be human. Through this dynamic of teacher and student, they both reached for a momentary escape from their roles as weapons. But that attempt is violently torn apart by the reality of their mission.

What they shared wasn't love; it was the inescapable pain of being "objects." The way the author ties these threads together is bone-chilling.

Every lesson, every moment of connection—it was all part of a cruel, pre-programmed script designed for one purpose: slaughter.
