Saijaku na Boku wa "Kabenuke Bug" de Nariagaru

All Henri Cleats has going for him is a single skill called Evasion. In a world where adventurers grind dungeons and stack abilities, having a single defensive skill with zero attack power is basically a death sentence for your career. He gets kicked out of his party almost immediately — they don't even feel bad about it. The thing is, Henri can't afford to quit. His younger sister Colette is sick, and adventuring is the only way he can pay for her care. Then he figures out something nobody expected: his Evasion skill lets him phase through walls. Not dodge attacks better, not sidestep danger — literally walk through solid stone. Which means he can skip straight to the end of dungeons without fighting the boss, claim the first-clear rewards, and do it again somewhere else. It's basically a speedrun exploit turned into a survival strategy. Instead of getting stronger the normal way, Henri games the system, stacking rewards and resources while everyone else is slugging it out floor by floor. The sibling dynamic gives the whole thing an emotional anchor that keeps it from feeling like pure power fantasy. If you liked the underdog-to-overpowered trajectory of Arifureta: From Commonplace to World's Strongest or the dungeon-crawling world of Is It Wrong to Try to Pick Up Girls in a Dungeon?, this TV series based on a light novel hits a similar space. It also shares DNA with The Rising of the Shield Hero in how it handles a protagonist everyone writes off too early.
