When the abyss descends, everyone awakens a class—and that class determines their worth. Warriors are respected. Summoners are treated as trash. So when Lucas chooses to become a summoner, the entire awakening ceremony erupts in laughter. But they won't be laughing for long. With an S-rank talent, Lucas can summon an entire army all by himself. As he sweeps through the abyss, breaks records, and crushes the geniuses who once mocked him, this so-called weakest class becomes their worst nightmare. They said he was worthless. Now, nothing can stop him from claiming the title of the strongest in the Federation.
