LIGHT'S GOT A LITTLE LIST... After bringing the hammer of justice down on the adventurer-slayer Kyto and his fast-talking accomplice Yanaaq, Light receives some excellent news! Ellie reports that preparations for Light's revenge on Sasha the elf are finally complete. The stage is set for Light to storm the Elven Queendom with all the power he's built up over his three years in the Abyss—and another name is about to be crossed off his ever-growing kill list!

UNLIMITED GACHA VS INFINITE EVIL! Light and company find their adventuring interrupted by reports of suspicious killings in the very same dungeon they're crawling. Tempted by the prospect of boosting his rank—not to mention the generous reward promised by the Dagas Adventurers' Guild—Light sets off to catch the killers.  The hunt takes a personal turn, however, when a party of innocent young adventurers gets slaughtered in the crossfire. Light's quest for vengeance will have to wait as he turns his wrath on a new target!

A MOUTHFUL OF VENGEANCE! The young adventurer Light was betrayed by his party and abandoned in the deepest levels of a dungeon called The Abyss with nothing but his magical gift of Unlimited Gacha-a power that had previously created unlimited garbage. But supercharged by The Abyss itself, the gacha unlocks its full potential and Light unlocks new allies: an astounding army with which to exact his revenge and conquer the world! Having dispatched the beastman Garou, Light sets out to find Sasha the Elf. In the meantime, he and two companions head to the bordertown of Dagas to gather both information and glory. The Dagas dungeon offers ample opportunity to raise their adventuring ranks...so long as nobody cuts the line!

A kid named Light is the only human member of the adventuring party Legion of Races, but humans are by far the weakest race in his world. When his comrades abandon him to the lowest levels of a dungeon, Light resorts to the gift of Infinite Gacha to create a harem of Lvl 9999 allies! With his powerful and beautiful new friends by his side, can Light escape the dungeon and exact vengeance upon the Legion of Races... and the entire world?
