Uncover the revival of a lost GBA RPG named Yokai Buster by former Metal Slug creators, set to launch with nostalgic charm and modern flair.

A New Chapter for Classic Game Creators

Back in 2023, a fresh spark ignited in the gaming world when ex-developers from SNK and Irem joined forces to establish Kohachi Studio. This team of seasoned veterans is juggling two intriguing projects simultaneously. The first is an adrenaline-pumping run ‘n gun game called Black Finger Jet. But the real gem? They’re resurrecting a long-forgotten RPG originally meant for the Game Boy Advance.

Yokai Buster: Navinosuke – From GBA to Nintendo Switch

Japanese gaming site Gamespark revealed that the revived title will be named Yokai Buster: Navinosuke. This RPG was initially developed two decades ago within SNK’s walls but never saw the light of day. Now, with the talented Akio Oyabu—the artist behind iconic series like Metal Slug and R-Type—leading the charge, the game is being reborn for a new generation.

Fans can expect its official release in early 2026 on the Nintendo Switch platform, blending classic charm with up-to-date gameplay.

Dive Into the Mystical World of Yokai

Curious about the eerie spirits you’ll encounter? The official Kohachi Studio website offers a sneak peek at some of the yokai featured in the game. Among these captivating creatures are Zenko (a fox spirit), Gashadokuro (a giant skeleton), Tengu (a bird-like goblin), and many other fascinating Japanese supernatural beings.

Each yokai comes with unique attributes and a special skill set, making battles not only strategic but also deeply immersive. From the screenshots released, combat appears to be turn-based, while exploration adopts a traditional top-down perspective, offering a nostalgic yet fresh approach.

The game promises full language support for both English and Japanese players, making it accessible to a wide audience.
