In this episode of Manga with Josh, I shine a spotlight on Sun-Ken Rock, an underrated and gritty seinen series created by Boichi—the same artist behind Dr. Stone. Running from 2006 to 2016 with 25 volumes, Sun-Ken Rock blends intense action, crime, comedy, and raw emotion in a way few modern manga do.

I break down the premise, from Ken’s wild journey from Japanese delinquent to South Korean gang leader, to the surprising twists involving the Yakuza, romance, betrayal, and the rise of his mafia-style crew. We also dive into Boichi’s signature art style, the over-the-top battles, the dark humor, and why this series stands out in a manga landscape filled with isekai clones and system-based power fantasies.

If you’re into seinen manga, battle series, mafia stories, or you just love discovering hidden gems that deserve an anime adaptation, this episode is a must-listen. I also share why Sun-Ken Rock became one of my favorite reads during the late 2000s and why it still holds up today.
