I'm in a Different World, and I'm a Demon King.

Wu Fan traveled to a different world while playing a game, and fell into the harpy's lair and almost died young. Unexpectedly, he was raped by the leader of the Banshee clan. Fortunately, the system was so powerful that it was a blessing in disguise. "Why do you, as a human, help monsters? You traitor to humanity!" "You humans are too despicable, and I, Wu Fan, disdain to associate with you!" "Your Highness the Demon Emperor, the Elf Princess wants to see you and has been waiting outside the palace for a long time." "What kind of spirit is this? I'm not familiar with him at all. I'm afraid my wives will misunderstand me." "Father, another sister has sneaked out of the Kingdom of God!" "Oh, I understand, let them play. Anyway, there is no one left in this world who can fight." "Father, why do humans call us angels?" "Because you are all my wings!" This novel and its characters are purely fictitious.
