Tenshi wo Ikasete Item Get!! Zecchou Gacha de Dungeon Kouryaku!

Haruma Kouzai’s ordinary life comes to an abrupt end when he is suddenly transmigrated to a bustling town built around a mysterious dungeon. Upon his arrival, he is granted a unique ability known as "Summon Angel." Despite its divine name, the skill does not call forth heavenly beings freely. Instead, it operates on a highly specific transaction: summoning an angel requires Haruma to pay a very particular price. This cost involves providing intense physical pleasure to the summoned entity. To successfully activate the skill's true potential, Haruma must bring the angel to complete climax. Only then does the system reward him with powerful cheat boosts determined by the encounter. Armed with this unconventional and deeply intimate mechanic, Haruma begins his journey through the perilous dungeon, turning every summon into a provocative gamble for ultimate power in this ecchi-filled isekai adventure.
