| nicovideo | youtube | cosMo's cover (is awesome and needs more love (´・ω・`) )

( romaji only )
Note: cosMo reversed the kanji for the song title, it would normally read: 
少女の空想庭園 (Shoujo no Kuusou Teien) 
"Girl's Fantastical Garden"
But "Anti the Fantastic garden" is the English given for the song.
