グラップラー刃牙 外伝 [Grappler Baki Gaiden]

A single-issue spin-off from the Grappler Baki universe, this 1999 Akita Shoten one-shot expands the world of underground martial arts combat. While the main series focuses on Baki Hanma's journey, this gaiden offers a brief, self-contained look at a different fighter or scenario within that brutal arena. It's a minor but notable entry for dedicated fans of the franchise, showcasing the wider scope of its creator's violent, over-the-top fighting mythology.
