Declan awakens as an SSS-class Swarm Tamer after his family abandons him. They cancel his engagement and steal his inheritance, leaving him with only a frail mantis. Dismissed as worthless, he is suddenly transformed when his system triggers. An unstoppable insect army erupts from within him. The swarm crushes his rivals and shatters his family's estate. The man they mocked now wields world-shattering power.
