This song was part of the EXIT TUNES compilation album Vocalostar. "Cantarella" is about an obsessive and intoxicating romance: a man (KAITO) who tries to keep his love for a girl (Miku) hidden and approach the girl in order to make her his. Taking time by the forelock, he gets closer to her, and he finally reveals himself. KAITO and Miku personify Cesare and Lucrezia Borgia, known for their suggested incestuous relationship even though KAITO and Miku are not related. This song has entered the Hall of Legend.
