BODY: Fans of the sword-swinging Taisho-era hit have a new reason to drop into the battlefield. On August 2, 2026, NetEase Games kicked off the second wave of its Demon Slayer: Kimetsu no Yaiba collaboration inside its hugely popular battle royale Knives Out (known in Japan as Kōya Kōdō).
The centerpiece is a limited-time mode called "Infinity Castle Clash" (無限城激闘). Rather than the usual last-player-standing formula, this mode drops players into a sprawling 3D recreation of the anime's Infinity Castle — the shifting, gravity-defying labyrinth that serves as the demons' stronghold in the franchise's climactic arc.
The twist is combat itself. Players don't just shoot; they channel Breathing techniques, the signature fighting styles of the Demon Slayer Corps, to take down the demons roaming the map. It's a notable pivot for a game built around firearms and vehicles, leaning fully into the melee-and-magic fantasy that made the source material a global phenomenon.
The timing is no accident. The Infinity Castle theatrical arc has been one of the biggest anime events of the past two years, making this the perfect moment for NetEase to revisit a partnership that clearly performed well the first time around.
The insider take
From Tokyo, this is a textbook example of how China-developed mobile titles keep their Japanese audience engaged: not with one-off skins, but with mechanically distinct modes that lend the collaboration real weight. Knives Out has long punched above its weight in Japan — it's arguably more culturally embedded here than in its home market, thanks to relentless anime and idol tie-ins. Pairing it with Demon Slayer at the exact moment the Infinity Castle films dominate the box office is savvy scheduling that Japanese publishers themselves have learned to respect.
