Lastly, here’s an overview of the series via MyAnimeList:
The series follows Henri Cleats, an adventurer who only has a single skill: Evasion. Wanting to take care of his sickly younger sister Colette, he joins a party. However, due to weak attack power and lack of skills, he is expelled from this party.
However, it turns out that his evasion skill comes with a bonus: he is able to pass through walls and reach the end of dungeons without defeating the boss. Thus, he is able to claim a dungeon’s First Clear bonus more than once. With his newfound knowledge, Henri sets out to clear as many dungeons as he can while also leveling up his power.
