The animation punches hard enough that even compressed recap footage feels essential. The first two episodes of Season 2 hit different when they're not buried between a full season rewatch, you get the power escalation and new threats without the wait. Fair warning: this is a highlight reel, not a story, so it's built for people who've already committed to the series, not newcomers looking for an entry point.
Ten years after gates to monster-filled dungeons opened on Earth, certain people called hunters gained supernatural powers to fight what lies inside. Sung Jinwoo takes on hunter work to support his family, yet his feeble abilities earn him a reputation as the weakest hunter alive. A disaster during a dungeon raid leaves him close to death. He survives without explanation and wakes in a hospital to find that a mysterious system has chosen him as a player, giving him a way to grow his skills. Apparently the only one selected, he levels up rapidly and may be on course to become the strongest hunter in the world. ReAwakening is a feature-length compilation of the first season plus the opening two episodes of the second, an action fantasy adventure retelling his rise.
