If you’ve read the other pieces in this series — the four-layered spiral of Naruto, the purgatory-and-fire kanji of Demon Slayer, the knotweed and two-faced gods of Jujutsu Kaisen — you might expect Chainsaw Man to be the richest of all. It’s the biggest manga of its generation. The opposite is true. Tatsuki Fujimoto strips his names down to almost nothing, and the bareness is the point.
Start with the title. チェンソーマン — Chainsaw Man — is written in pure katakana, the script Japanese reserves for foreign and borrowed words, and it means exactly what it says. Not the blade that annihilates demons. Not a wheel of curses. A man. With a chainsaw. The hero of this story is named the way a child names a thing: by pointing at the most obvious feature and stopping there.
デンジ — Denji
The protagonist is デンジ (Denji) — katakana, no kanji, no meaning to mine. And that absence is deliberate. Denji is a boy so poor he sells his organs to pay off his dead father’s debt, who has never read a book, who dreams of nothing grander than bread with jam and a roof. A loaded, elegant kanji name would be a lie about who he is. He gets a flat, slightly rough, throwaway sound, written in the script with the least cultural weight. The name has no destiny in it because the character was never given one.
This is the inverse of how the prestige battle-manga name works. Tanjiro carries healing; Satoru carries enlightenment. Denji carries nothing — and a kid the world treats as disposable, handed a disposable name, is its own kind of writing.
パワー and ポチタ — the devils get pet names
パワー (Power) is the most honest name in the series: it’s the English word “power,” in katakana, given to a Blood Fiend who is loud, selfish, cowardly, and enormously strong. There is no kanji because there is no person underneath in the human sense — she’s a devil wearing a body, and Fujimoto names her like a force rather than a girl. The katakana keeps her permanently foreign to the human world she’s stomping around in.
ポチタ (Pochita), the little Chainsaw Devil who lives in Denji’s chest, gets a name in the same register — soft, round katakana, the kind of sound you’d give a pet. That’s the relationship: Pochita is the closest thing Denji has to a dog and a family at once. The names of the non-human characters cluster here, in katakana, in the warm and slightly silly register — marked, deliberately, as not from around here. It’s the same instinct we keep running into: katakana is the script of the foreign and the other, the same reason Mikasa and Anya stay in katakana in their own series.
早川アキ, 姫野, 岸辺 — the humans get geography
Now look at the human cast, and notice how ordinary the surnames are. They aren’t loaded with virtue or myth. They’re landscape.
早川 (Hayakawa) — 早 “fast/early,” 川 “river” — “fast river.” A common, real surname. Aki’s given name, アキ, is again katakana, plain on a plain man: a serious, dutiful devil hunter with nothing fanciful about him. 姫野 (Himeno) — 姫 “princess,” 野 “field” — is the one faintly pretty name in the bunch, and it belongs to a chain-smoking, hard-drinking veteran who doesn’t last. 岸辺 (Kishibe) — 岸 “shore,” 辺 “edge” — means, simply, “the water’s edge,” the bank of a river. The strongest, most dangerous human in the early series is named after the plain fact of a shoreline. 東山コベニ (Higashiyama Kobeni) pairs 東山, “east mountain,” with a katakana given name.
Fast river. Princess field. Water’s edge. East mountain. These are the names of places, handed to ordinary, frightened, expendable people in a brutal world — not the destiny-names of heroes. Where Gege Akutami reaches into the Nihon Shoki and Koyoharu Gotouge reaches for the word purgatory, Fujimoto reaches for the surname of someone you’d stand next to on a train.
It would be easy to read Chainsaw Man’s names as Fujimoto not bothering. The truth is the reverse: the plainness is doing exactly what the ornate names do elsewhere, just from the other direction. A poor boy gets an empty katakana name because the world emptied him out. The devils get pet-names and loanwords because they don’t belong to the human order. The humans get the names of rivers and hillsides because they are, in the end, small and mortal and ordinary, which is the whole tragedy of the thing. Not every great name is a riddle. Some are a flat, deliberate refusal to pretend — and that refusal is the meaning.
We’ve now decoded four casts: the spiral of Naruto, the fire of Demon Slayer, the curses of Jujutsu Kaisen, and the deliberate plainness here. If you’re curious what your name looks like across the three Japanese scripts — the phonetic katakana these characters live in, plus meaning kanji and ateji — try it in the tool, or read how Japanese names actually work for the full picture.
