Backstabbed in a Backwater Dungeon: My Party Tried to Kill Me, But Thanks to an Infinite Gacha I Got LVL 9999 Friends and Am Out for Revenge (Manga) Vol. 2

"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!"--
