“If anything, I feel like Attack on Titan is what broke it. Once Attack on Titan became the talk of the town, the 'mystery payoff (lol)' and the 'cryptic hint-dropping' got really blatant.”

どっちかっていうと進撃の巨人に壊された気がする 進撃の巨人が話題になってから「伏線回収()」や「匂わせ」が露骨になった

  • Honestly you could probably also win by gathering a bunch of female corps members and having them all scream """STOP IT, Hakuji!!""" in unison.

    女隊士集めて「「「もうやめて狛治さん!!」」」って叫ばせても殺れそう

  • Demon Slayer might have been the finishing blow, but it had already started going wrong before Demon Slayer.

    鬼滅がトドメになったのかも知れないけど、鬼滅の前からおかしくはなり始めてた。

  • Saw this take online: it was the power of Keizo, the Soryu master. Rengoku's a swordsman, so he'd NEVER make someone drop their blade — that's basically getting your junior killed. Keizo was a martial artist, so he knocked it loose so the kid would throw a punch instead.

    ネットで見たけど、素流師範のけいぞうさんの力だと思う。煉獄さんは剣士だから剣を手放させるような事は絶対しない。後輩を死なすようなもんだからそれ。 けいぞうさんは武闘家だから殴らせるためにスッポ抜かせた。

  • I just can't shake the feeling that Oda genuinely has a complex about Demon Slayer.

    なんとなくマジで鬼滅にコンプレックス抱えてる気がするんだよな尾田っち

  • Even in death, the man who refuses to let anyone die — Rengoku.

    死してなお、誰も死なせない男、煉獄

  • Gotouge once wrote, 'Demon Slayer became this widely read because of all of you. You're welcome to go ahead and say you raised Demon Slayer yourselves!' That line stuck with me. The kindness, the humility — you can feel he's genuinely grateful to the readers. We're the ones who want to thank him. That's why I love the guy.

    吾峠先生はコメントで「ここまで読まれる作品になったのは皆さんのおかげです。自分が鬼滅を育てた!って言ってもいいです!」って書いてあったのが印象的でした。 文章から優しさというか謙虚さというか、本当に読者に感謝してくれてるんだなってのが伝わる。こっちが感謝したいのに。 だから好き。

  • Looks like an honorable stand-up-fight boss, but actually the win condition is: • Lecture him that 'the strong protect the weak' to jog a fragment of his Master loose • Notice he's summoning his fighting aura and enter the Transparent World • Catch him off guard, declare 'I'm cutting your head off NOW!' with full honor, and behead him • Before he fully regenerates, deck him with a bare fist to make him completely remember his Master's punch ⚠️ Note: he instantly regenerates from any attack, every one of HIS hits is lethal, and he out-stats you in basically every category. You have to clear ALL of that or he regenerates after decapitation and wipes your whole party. Worst. Boss. Ever.

    正々堂々と戦う系のボスと見せかけて ・「強いものは弱いものを守る」と説法して、師匠の片鱗を思い出させる ・猗窩座が闘気を呼んでることを見抜き、透き通る世界に入る ・猗窩座の不意をついた上で、「今からお前の首を切る!」と正々堂々と発言をし、首を切り落とす ・完全に再生するまでにグーパンして師匠の拳を完全に思い出させる ⚠️尚、基本的に相手はどんな攻撃を受けても瞬時に再生し、1発1発が致命傷の攻撃をしてくる上に、基本的にあらゆる面で自分より格上である これ全部クリアしないと首を落としても再生し全滅するのクソゲーすぎる

  • Demon Slayer and Attack on Titan played a part, sure, but in the end Oda became the hare in the tortoise and the hare. While he was being showered with 'you're No.1,' the people quietly putting in the work simply delivered the results.

    鬼滅とか進撃の巨人の影響もあるだろうけど結局のところ、尾田先生はウサギとカメのウサギになってしまった 自分が1番だとチヤホヤされている間にひたむきに努力していた人達が結果を出しただけ

  • If the blade slipped because Rengoku's will is in it, then Rengoku is saving the very person who killed him. It's the payoff to what all three of them set in motion back on that train — gives me chills. Rengoku didn't just let no one die; he even saved Akaza, the demon he hated.

    煉獄さんの意思が宿った故のすっぽ抜けなら煉獄さん的には自分を殺したやつを救ってることになってて。 列車での3人それぞれが織りなした結末でエモいよ。 煉獄さんは誰も死なせなかったどころか 嫌いな猗窩座さえも救ったんだよ。

  • 'Saint' Eiichiro Oda and One Piece 'got crushed by Demon Slayer' — but here's the catch: Demon Slayer didn't actually win. 'Saint' Oda just wrestled himself and keeled over on his own.

    尾田栄一郎聖とワンピースは「鬼滅の刃に惨敗した」けど鬼滅の刃が勝った訳じゃないのがミソ 尾田栄一郎聖が独り相撲して勝手に死んだだけ

  • "Hakuji finally beat Akaza" is such a beautiful way to put it.

    狛治が猗窩座に打ち勝てたっていい言葉

  • A stark difference from a certain 'Oda' (said with a sneer) who mistook it all for a one-man achievement 😂

    1人の手柄と勘違いした尾ミャク田との明確な違い😂

  • So basically it's Rengoku going, "It's alright now, young Kamado! Come to me!"

    煉獄さん 「もういいんだ竈門少年! 俺のとこに来い!」 ってことか

  • He just psyches himself out and flops. Same story every time.

    勝手に意識して失敗してるだけ定期

  • There's also the theory that an imaginary Master or Koyuki was there shielding Akaza and pulled the blade away from him.

    実はこの場にいたイマジナリー師範or小雪が猗窩座を庇って刀取り上げた説も。

  • It's been off the rails since way before Demon Slayer even started.

    鬼滅始まる前からずっとおかしかったよ

  • I love that little strangled "—!!" noise Giyu makes.

    義勇さんの「ッッ!!」みたいな声好き

  • Nah, it got boring after the Marineford War made it massive and he started hanging out with celebrities.

    いや、頂上決戦で売れて芸能人と遊びだしてからつまらなくなった。

  • Rengoku's tsuba (sword guard) protected Kotetsu too, so maybe his spirit really is dwelling in there…

    煉獄さんのつばは小鉄も守ってるしほんとに煉獄さんが宿ってる…かもしれない。

Editor's note

The Infinity Castle reactions here get granular in a way overseas coverage rarely does — Japanese fans read Tanjiro's slipping blade as “Hakuji finally beating Akaza.” And when “did Demon Slayer kill One Piece?” went around, the Japanese take was blunt: Demon Slayer didn't win; One Piece lost on its own.
