Understanding the Context
What Is Seinan? Defining the Genre Like Never Before
The term seinen (青年, literally “young man”) refers to manga created primarily for adult men—typically aged 18–45. But it’s more than just an age demographic: seinen means a storytelling style marked by complex themes, nuanced character development, and a willingness to explore mature subject matter.
Unlike shōnen (aimed at young boys) or josei (aimed at adult women), seinen bridges the gap between youthful energy and adult depth. The works often tackle psychological tension, societal issues, existential questions, or slice-of-life realism, reflecting the inner lives and struggles of male and sometimes female protagonists at pivotal life stages.
