Iterate: Chosen by the maw

In a world ripped open by jagged scars in reality, monsters spill into the cities, devouring everything in their path. Humanity survives by clinging to Phase Shift-a dangerous power drawn from the world within the scars themselves, wielded only by the gifted. Ryuji was once a prodigy, destined to walk through the deadliest of dungeons and save the world. But the world betrayed him first. Orphaned, shunned, and framed by those he trusted most, he's left alone to scrape by, haunted by mistakes he can never undo.
