When Light is expelled from the Tribes" Concord, his old allies immediately turn hostile. He narrowly escapes this treacherous betrayal, only to find himself plunged into the Abyss"s deepest layer, the realm"s most perilous dungeon. To survive the predatory beasts he relies on his sole spell, Unlimited Gacha. Previously it yielded only useless trinkets; now Mei—a stunning Level‑9999 combatant in a maid"s garb—materializes. Three years later, Light has built his own dominion within this forsaken lair, summoning additional Level‑9999 champions who pledge unwavering loyalty. As a formidable Level‑9999 Overlord, he now intends to rise above the abyss and exact vengeance on each of his former comrades.
