TenkafuMA!

The arch-demon Caesar lives a hedonistic but ultimately stagnant life from atop his throne in Hell, quickly becoming bored of bedding the same women and being surrounded by the same dull minions every day. His luck changes when, while searching for new concubines, he stumbles upon a set of ancient relics housing the spirits of arch-demons past, who impart their power unto him to aid him in conquering the world. Empowered by his renewed vitality, Caesar sets out on a quest to conquer the territories - and women - of the other kingdoms of Hell and the realms beyond.

TenkafuMA! is a hentai turn-based role-playing game with gacha elements. As Caesar, players form a team of up to five characters with varying skills to clear stages by fighting enemy teams. In each turn, each unit can be set to either attack (which deals damage to the enemy) or defend (which reduces the damage received by the unit in the enemy's turn). Once certain conditions are met, characters can also use an Ultimate Skill which is significantly more powerful than their standard skills. Characters are attributed one of five elements (Fire, Wind, Water, Light, and Darkness), which determines their effectiveness against characters of other elements. New characters can be acquired via a gacha system where the player can spend virtual or real-world currency to gain a random selection of characters from a pre-determined pool.

There are several other game modes in addition to the main campaign as well as unique quests from periodic updates and events. One such game mode is the Demon Spire, which contains stages with special challenges. Outside of combat, the player can use items to level up their characters or 'discipline' them with sex toys to unlock sex scenes.
