Forty years after wrapping up one of manga's most beloved sports series, Motoka Murakami is bringing Musashi no Ken back. The creator announced via Twitter that he's drawing a new one-shot story set to premiere on Shogakukan's Sunday Webry platform on May 20.

According to Murakami's post, the story reunites "those two" characters for another clash—teasing a rematch or confrontation between the series' key rivals. The one-shot arrives as part of a larger celebration on Sunday Webry featuring classic manga creators, with Musashi no Ken kicking off the event.

Musashi no Ken originally ran in Weekly Shonen Sunday from 1981 to 1985, following a young kendo prodigy named Musashi, whose parents named him after the legendary swordsman Miyamoto Musashi in hopes he'd live up to the name. The series became a cultural touchstone for sports manga fans, spawning a 72-episode anime adaptation that aired from 1985 to 1986.

Murakami has remained active in recent decades despite focusing primarily on his historical medical manga JIN, which found new life through multiple adaptations. Netflix began streaming two Japanese live-action JIN series in December 2024, both starring Takao Ōsawa. The property has also inspired Korean television and stage adaptations, including a 2012 production by the Takarazuka Revue.

The artist has also championed fan engagement, opening a Patreon account in 2017 to fund an English translation of JIN, offering early chapters to supporters.

This new Musashi no Ken one-shot represents a rare return to the series that defined Murakami's early career. For longtime fans of the manga and anime, it's a chance to revisit the world of kendo competition and see how the creator approaches the characters four decades later. The story arrives on Sunday Webry starting May 20.
