Gift from the Princess who Brought Sleep (also known as Princess Sandman's GIFT) concerns Margarita Blankenheim, shown as the daughter of a doctor, who is made to marry Caspar, a man who is blinded by money. She learns form her friend Julia how to make a medicine which puts everybody to sleep. She then makes everyone drink her 'remedy', which in actual fact is just a poison. After putting everyone in the city to "sleep," in the end she commits suicide by drinking her own poison.

At the end of the PV, a dialogue between Elluka Clockworker and Guumilia is shown, hinting the relationship of Margarita and Julia with Pere Noel. This song's keywords are 「あなたの幸せの為に」 "For the sake of your happiness", and its initial phrase is 「さあ　眠りなさい・・・」 ("Now, go to sleep..."). The official English title of the song is "Belphegor's Gift".
