Backstabbed in a Backwater Dungeon: My Party Tried to Kill Me, But Thanks to an Infinite Gacha I Got

A kid named Light is the only human member of the adventuring party known as the Concord of the Tribes... but humans are by far the weakest of the races. When his comrades abandon him to the lowest levels of the dungeon, Light resorts to the gift of Infinite Gacha to create a harem of Lvl 9999 allies! With his new, and sexy, friends, Light can escape the dungeon, and more importantly, take revenge upon the Concord of the Tribes, and perhaps even break the entire world!
