When the xenoterran invasion hit, ordinary people started developing superpowers overnight, and the only thing standing between the world and the monsters pouring in was whoever was strong enough and willing to fight back. Some of those newly superhuman people became protectors. Others didn't. Kang Lim is a high school student living a double life as White Cap, a vigilante superhero fighting off xenoterran attacks while keeping his identity hidden from everyone around him. On the surface it's a fairly familiar secret-identity setup, but the series keeps pulling back the curtain on how the xenoterran actually got here, and the deeper Kang Lim digs, the clearer it gets that the invasion wasn't as random as everyone assumes.
The series earns its Mature rating by actually treating the stakes like they matter, superhuman fights have real consequences and real body counts, and the conspiracy simmering underneath the monster-of-the-week structure gives long-time readers something to keep chasing besides the next fight. Splitting its cast between altruistic heroes and superhumans who turned their power toward worse ends also keeps the world from feeling like a simple good-versus-monster story, there's real tension in not knowing who's actually on your side. Supp, who both writes and draws the series, has kept a consistent visual identity and a distinctive art style across a genuinely long run, and having one creator steering both story and art for this long shows in how deliberately the bigger mysteries get seeded and paid off. At over 100 episodes and two seasons in, it's also proven it can sustain an ongoing mystery instead of stalling out.
This is a long-running series with a real backlog at this point, so newcomers are signing up for a genuine time investment rather than a quick read. The Mature rating means real violence and darker content, which won't suit readers looking for a lighter, all-ages superhero story closer to typical spandex-and-optimism fare. And because the conspiracy plot unfolds gradually across a long run, individual arcs can feel more like set-up for a bigger reveal than fully satisfying on their own.
If you want a superhero webtoon that treats its monster-invasion premise as the surface of something bigger rather than the whole story, this has sustained that mystery convincingly across a long run. It's darker and more of a commitment than typical superhero fare, and worth it for readers who want their secret-identity story to actually be building toward something.
