Sshhh. Princess Syalis is trying to get a good night's sleep. Some shut-eye. Forty winks. Catch some Z's. Long ago in olden times when people and demons lived together in well, disharmony really, a demon king kidnaps a human princess and imprisons her in his castle. Bereft, the princess's subjects, beat their chests in anguish until a hero arises to spearhead "Project Rescue Our Princess". While waiting for her knight in shining armor, what's an imprisoned princess to do? Teddy-bear guards with bat wings are all very well, but her dungeon cell is boring. So, she decides to wile away the long hours by sleeping. Now if only she could get comfortable and didn't suffer from insomnia. 不给公主打满分，怕她打我……。じゃあ、おやすみ（✽＾㉨＾）。嘶呀一响，我也秒睡。不必深究。在魔王城当魔王。可爱公主的魔王城团宠故事。一部姑且还行的泡面番吧。可可爱爱的沙雕剧。甜甜甜！安眠大法！。评论。 这是一个人类与魔族共存的世界，但是世界的支配权还是掌握在人类的受众。一天，魔王抓走并囚禁了人类公主栖夜莉丝（水濑祈 配音），并且向人类发出了勒索信，要求人类用世界的支配权来换回公主的自由。为了拯救公主，勇者拂晓（下野纮 配音）踏上了充满了危机的旅途。 然而，被囚禁的日子实在是太过于无聊了，古灵精怪又闲不住的栖夜莉丝决定在魔王城里找点乐子。无论是恶魔教会的法师雷欧纳多（石川界人 配音）还是世代侍奉魔王的忠犬哈士奇（小林亲弘 配音），甚至连威风凛凛的魔王（松冈祯丞 配音）本人，都被公主的恶作剧给耍得团团转。
