Buffed by Bugs: The End of the World

After an ordinary adventurer, Zion, was betrayed and eaten by a monster, his final regret was being "no better than a cockroach." The Cockroach God took his lament seriously! Now, Zion is reincarnated—as a tiny, six-legged roach in a world full of terrifying monsters and superpowers. Stripped of his strength, this former human must use his new, disgustingly resilient body to scratch, skitter, and survive against impossible odds. His action-packed quest for revenge starts small, but his rage is immense!
