I'm a succubus who gathers energy by clearing System missions, adept at the game of love. One day, right after completing a honey trap mission, I was sent to a SSS-level horror game at the very next second. The boss was invincible and bloodthirsty, watching coolly as other players rested in pieces before turning to the rest of us. "Now choose—how do you want to die?" While other players were wetting their pants and trying to find a loophole to survive, I picked up on something different. A handsome, powerful target beneath that cold, horrific exterior. Hence, when he reached me, I smiled enigmatically as I told him my wish. "I wish to be conquered by a truly powerful Entity, dominated from soul to flesh, and to die in pure ecstasy." I watched him pause in shock and added, "Oh, and you must do it yourself."
