Crunchyroll adds KinnikuNeko: Super Muscle Cat to mobile Game Vault

Crunchyroll’s Game Vault is about to get one of its strangest additions yet: KinnikuNeko: Super Muscle Cat, a 2D platformer about a bodybuilder cat saving humanity after an alien wipeout. The mobile version is listed for Crunchyroll’s Android vault with pre-registration live and a planned release date of May 31, 2026, turning the game into a perk for Mega Fan, Ultimate Fan, and Annual Mega Fan subscribers rather than a standalone storefront buy.

That matters because Crunchyroll is clearly using Game Vault as more than a dump for library filler. The service launched on November 7, 2023, on Android and iOS in more than 200 countries, all with no ads and no in-app purchases, and Crunchyroll said in October 2025 that it wanted the vault to reach 100 titles by summer 2026. KinnikuNeko fits the strategy: it is the kind of offbeat, personality-first release that gives the subscription some identity instead of just padding the catalog.

The game itself started on Steam on March 19, 2024, with Kamotachi as developer and Mameshiba Games as publisher. Crunchyroll’s own description leans into the pitch hard, calling it a wild 2D platformer with action, humor, mini-games, and retro anime vibes. The story keeps a couple of humans around, Lemon and Keita, as the chaos escalates around General Pitaya and her minions, and that absurd setup is really the selling point. If the premise sounds too weird to explain in one breath, that is exactly why it works.

On mobile, KinnikuNeko looks best suited to players who want a compact platformer with clear controls and enough visual joke density to stay memorable after one session. The move list is simple but specific: punch, climb, meow, chain a three-hit combo, use a knee-dive aerial attack, a downward slide, and a roll. Crunchyroll’s listing also highlights hidden collectibles, replayable levels, and a dedicated MEOW button, which tells you this is built for repeat bites rather than long grind sessions.

For subscribers, that is the real value test. KinnikuNeko will not make Game Vault feel mandatory on its own, but it does make the service feel more curated. If you want a weird, ad-free platformer with an actual sense of style, this is the sort of oddball that justifies keeping the membership active.
