"Blair! I am very angry now! The level of anger has reached the highest level in history! Are you ready!" The plump and mature angry demon king.
"Blair, would you like to dance with me?" The gentle and pleasant demon king asked.
"Blair~ You made me into this look, then you have to be responsible to me and let me enjoy it~" The Demon King of Desire with spring in his eyes.
"Blair, eat." The gluttonous demon king with a petite figure and childlike face.
"Brave, well done! Let me meet you, my lord! Lazy demon king Blair's wives!"
