How come there are succubi in this dungeon?

Everyone knows adventurers enter dungeons for their treasures, but the dungeon lord, Caesar, thinks differently. He wants to see beyond the surface. Adventurers face so much pressure every day; after obtaining the treasure, they'll surely want to enjoy themselves, right? So Caesar lets them enjoy themselves in the dungeon, where beautiful succubi await. Adventurers want to fight but not touch the flesh? Caesar bestows relics and enchants their weapons. Adventurers also want a pet, but what pet is easier to raise than the Pokémon created by Caesar? What, adventurers have dreams too? Come to Caesar's dungeon; everything you seek is here.
