"drop pop candy" is an original song by Giga. It is about unrequited love. An alternate version, featuring Giga-P and Reol, was uploaded at the same time.

While the VOCALOID MV focuses on a pink-haired girl, the utaite MV focuses on Reol. The pink-haired girl seems to be representing Giga-P since she has a serial code on her arm, like the CV series, that says GIGA, on the cover of No Title+.

This song has entered the Hall of Fame in less than 7 days since its release. It later entered the Hall of Legend.
