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

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? (Source: Seven Seas Entertainment)
