The Seven Demon Kings: Taming the Holy Knight

[Serious Version] Drawing power from all the faith in the world, The Knight is born from the world's righteousness, Gathering the power of justice, blessed by the Goddess of Light, Halena. But where there is justice, there must also be evil, Drawing power from all the Negative Energy in the world, The Demon King is born from the world's wickedness, Gathering the power of evil, blessed by the Goddess of Darkness, Futili. The cycle of dreams, the suffering of reincarnation. What kind of future awaits the three girls? Will it be sorrow or joy, or neither sorrow nor joy? [Uninhibited Version] Gather the power of seven Demon Kings, and you can summon Dragon Ball!? No, wait, you can go home!? Three girls download an R-18 online game late at night, and end up transmigrating. What? We're Demon Kings! Come on, we were all raised by our motherland to be upright Young Pioneers. Grace: "Ah, challenges and all that can wait until I've had enough sleep." Nemesis: "I hear the voice of the future." Alexis: "Holy Knights? They're nothing special." And so, the three girls took their first steps into the world.

It actually suits the overall feel of this story quite well.)
