Blue Drops

Blue Drops is a Japanese vocal unit from Japan that brings together singer Hitomi Yoshida and Ikaros, the character voiced by Saori Hayami. The project combines a real vocalist with a fictional role in an anime music and character-song format. The unit is closely linked to Sora no Otoshimono. For the series, Blue Drops performed the opening theme "Heart no Kakuritsu (ハートの確率)" and the ending themes "Soba ni Irareru Dake de", "Kaeru Kara (帰るから)", "COSMOS", and "Sora to Maboroshi (そらとまぼろし)". Blue Drops was presented as an anime music unit built around the identity of Ikaros and the vocal presence of Hitomi Yoshida.
