Shinjiteita Nakama-tachi ni Dungeon

In a world divided into six races—humans, beasts, dragons, elves, dwarves, and demons—the human race is despised as the weakest and most inferior of all. To fight against this deep-rooted discrimination, a multi-racial party called Legion (The Race Union) was formed. However, behind their noble front lies a hidden agenda. Acting under orders from the non-human nations, their true goal is to locate the mysterious being known as “Master” and secure him for their own country. Raito, a young human boy possessing the rare gift “Infinite Gacha,” is welcomed into the Legion because his ability might be connected to the legendary Master. But when they discover he isn’t the one they’re looking for, Raito is betrayed and nearly executed. In a desperate attempt to survive, he accidentally activates a Transfer Trap and is teleported to the lowest level of an underground dungeon—alone. There, Raito faces a level 1000 mythical demon. On the brink of death, he desperately uses his Infinite Gacha—and miraculously draws a UR card: Mei the Seeker Maid (Level 9999). With Mei’s help, he overcomes the demons and barely survives. Vowing revenge on those who betrayed him, Raito decides to use Infinite Gacha to summon loyal allies and uncover the truth behind his near-death. Guided by Mei’s wisdom, he begins building power and influence deep within the dungeon. Three years later, Raito has forged the strongest underground nation. Now, he rises from the depths once more—determined to bring vengeance upon his traitorous comrades and expose the dark secrets of the world that once abandoned him.
