Haneda Girl Nintendo Switch Release: Studio Koba's Fast-Paced Action Arrives on eShop May 7, 2026

Studio Koba's Haneda Girl lands on the Nintendo Switch eShop on May 7, 2026, bringing a faster, more kinetic follow-up to the developer's cyberpunk-tinged 2D action work.

Known for 2021's Narita Boy, Studio Koba returns with a title that swaps the previous game's slower atmospheric pacing for high-speed combat and mech-assisted encounters on Switch and PC via Steam.

Haneda Girl casts players as protagonist Chichi Wakaba, tasked with defending the Data Empire from an invasion of Hackernauts.

Gameplay alternates between Wakaba and her tactical combat mecha M.O.T.H.E.R., creating a dual-layer action loop: Wakaba for precision, stealth, and mobility; M.O.T.H.E.R. for durability and heavy firepower.

Studio Koba says the game emphasizes precise input and addictive session structure, and highlights a standout techno soundtrack as a core design pillar for pacing and player engagement.

Mechanically, Wakaba wields a light katana named KenChan and is designed as a glass cannon archetype.

She features stealth, temporary invisibility, and a super-dash ability that prioritizes speed and offensive output but leaves her vulnerable to a single fatal hit.

M.O.T.H.E.R. provides the necessary contrast, serving as the tough, bullet-spraying frame that clears tougher encounters and changes the tactical rhythms of each stage.

Haneda Girl is already available on Steam with a free demo for players who want to sample the combat loop and soundtrack ahead of the Switch release.

On Steam, the game received positive critical attention, posting an average Metacritic user score of 85 at launch.

That reception follows Studio Koba's earlier success with Narita Boy; our 2021 review awarded Narita Boy an 8 out of 10, praising its world building, thoughtful narrative, and satisfying combat systems.

For Nintendo Switch players, the May 7, 2026 eShop release provides a portable option to experience Haneda Girl's rapid action and mech-switching mechanics.

With a clear release date, Steam demo availability, and strong early reception, Haneda Girl positions itself as a notable indie action release for both Switch owners and PC players following Studio Koba's post-Narita Boy trajectory.
