Power wears breast pads in Chainsaw Man because she views breast size as a status symbol and wants to appear superior. It’s a detail that fits perfectly with her personality: vain, competitive, and obsessed with being better than everyone around her.
When the Breast Pads Are Revealed
The reveal happens in Chapter 12 of the manga. Denji, who made a deal with Power to help rescue her cat Meowy in exchange for getting to touch her chest, finally collects on the bargain. Something feels off during the squeeze, and a pad falls to the ground. Power casually explains that she uses breast pads to make her chest look bigger, completely unbothered by the reveal. Denji is stunned, but Power simply tells him he’s lucky to have touched “something so nice” and moves on.
Vanity and the Need to Be Superior
Power is one of the most egotistical characters in Chainsaw Man. She constantly boasts about being better than the humans she works alongside, frequently imagines ways to make people kneel before her, and claims abilities she doesn’t actually have. She’s childish, greedy, and almost entirely self-motivated. The breast pads are just another extension of this personality.
She treats physical appearance the same way she treats strength: as a hierarchy where more equals better. Fans have noted that she was visibly jealous of Makima’s chest at one point, which reinforces the idea that she sees breast size as a competitive measure. Power understands that larger breasts are considered attractive and fashionable among humans, and she wants to rank at the top of that ladder too. It’s less about attracting anyone and more about feeling dominant.
Despite her messy, half-dressed look (her jacket is almost always hanging off one shoulder), Power actually pays more attention to her appearance than most characters in the series. She’s one of the only characters shown wearing different outfits throughout the story, and she regularly has Denji or Aki help with her hair. The manga makes it clear at a later point that Power “knows she’s cute” and uses that to her advantage when manipulating people. The pads fit right into that self-awareness.
The Fiend Body Complication
There’s a deeper layer to this that the manga touches on. Power is a Fiend, meaning she’s a devil who took over a human corpse. In a later scene where she and Denji bathe together, she explains something surprising: she personally doesn’t care about her lack of chest size, but the body she inhabits does. The original owner of the corpse apparently had insecurities about her body and wore breast pads as a habit. Power inherited that impulse along with the body’s brain, and she admits she doesn’t fully understand why she continues wearing them. She just does it out of a kind of residual instinct from the corpse’s former life.
This adds an unexpectedly layered dimension to what initially seems like a simple gag. Power’s breast pads are partly her own vanity, partly a learned behavior from observing human beauty standards, and partly a lingering echo of a dead woman’s self-consciousness that Power carries without fully comprehending it.
Why It Works as a Character Detail
The breast pads aren’t just a throwaway joke. They reinforce several things about Power at once. Her competitiveness, her shallow understanding of human social dynamics, her willingness to deceive for even the smallest perceived advantage, and the strange, tragic reality of being a devil living inside someone else’s body. Power is a manipulator who will fake anything if it makes her feel like she’s winning, even something as trivial as cup size. At the same time, the habit connects her to a humanity she didn’t ask for and doesn’t quite understand, which is one of the quieter themes running through her character arc in Part 1 of Chainsaw Man.
