A swordswoman from Granblue just dropped into one of the strangest fighting games on Switch.
KAYAC announced that Narmaya — the long‑haired blade wielder from Cygames’ Granblue Fantasy Versus: Rising — is available today as a free guest character in Ketsu Battler via the game’s version 4.0 update. The arrival comes alongside the earlier guest addition of Beelzebub, making for an especially eyebrow‑raising crossover lineup.
Ketsu Battler, a Nintendo Switch exclusive in Japan since its December 2024 launch, bills itself as a one‑on‑one “butt‑shaking” fighter: players strap a Joy‑Con to their backside and translate twerks and squats into attacks and combos. That odd premise hasn’t stopped developer KAYAC from leaning into guest characters, and the Granblue additions are the latest example of how far the game will go to surprise its audience.
The cameo, in context
If you saw the teaser trailer you’d recognize Narmaya immediately — a familiar face for Granblue players — but dropped into Ketsu Battler’s chaotic arena she looks very much at home doing her thing. The update is free and available now for the Japanese Switch release; viewers can find the new trailer circulating on KAYAC’s channels.
Beelzebub preceded Narmaya’s arrival and was notable enough that staff involved with Granblue Fantasy Versus: Rising reportedly hosted Ketsu Battler’s first esports event on the same day Beelzebub went live. That’s a weird sort of endorsement: a high‑profile fighting team backing a Joy‑Con‑twerking contest. It speaks to how the crossover culture around fighters — and the willingness of developers to have fun with their IP — has expanded recently.
Why this matters (and why it’s fun)
Beyond the headline giggle, these guest drops are a smart move for a niche title. They draw attention from fans of bigger franchises, create shareable moments, and give KAYAC hooks for livestreams and events. Ketsu Battler’s gimmick is inherently memetic, and bringing recognizable faces from an established fighter helps the game reach players who might not otherwise stumble across it.
The switch between serious swordplay and silliness is part of the point: it’s spectacle and community bait at once. If you’re curious about how Nintendo hardware continues to host unexpected experiments, recent chatter around Switch 2’s lineup and third‑party support makes the platform’s future feel like fertile ground for this kind of eccentricity — see the discussion around Switch 2 launch plans and its growing momentum in the market in recent sales forecasts.
If you want to try it
Ketsu Battler remains a Japan‑only Switch release for now. The update that adds Narmaya is free, and you should be able to download version 4.0 from the eShop on a Japanese account. The game leans hard into local humor and spectacle, so expect showy crossovers and more seasonal or guest characters going forward.
Whether you’re a Granblue die‑hard curious to see Narmaya in a very different light or a streamer chasing the next ridiculous clip, this crossover delivers exactly what it promises: a toothy grin, a techy novelty, and a reminder that the fighting game space still has room for playful, unpredictable experiments.
