Gein

A shadowy figure lurking at the edges of one of manga's most celebrated samurai sagas, Gein made his entrance in Rurouni Kenshin #22 in 2005, brought to life by creator Nobuhiro Watsuki and Kenichiro Yagi under the Viz banner. His brief but memorable presence in the Modern Age places him squarely in the intense final chapters of the series, where he shares the page with heavyweights like Kenshin Himura, Hajime Saito, and Enishi Yukishiro — as formidable a gathering of swords and rivalries as you'll find anywhere in action manga. With only a handful of catalog appearances, Gein is a rare, concentrated presence — the kind of character that dedicated collectors and Rurouni Kenshin completists will want to track down precisely because he surfaces at such a pivotal, high-stakes moment in the story.
