Angel's 3P! The full animation tells the story of Hibiki Kanjing, who suffers from school phobia due to trauma in junior high school. His usual interest is to create songs using singing software. One day he received an email from a group of fifth-grade girls in elementary school──Crybaby Goto Jun. Strong-willed Momiji Nozomi. Yawning Kanjo Sora. The three who grew up together are as close as sisters, but they have the same troubles as Hibiki. In order to thank the place where they grew up and the benefactors who raised them, a ensemble of loli pop music sung with all their heart is about to begin!! This work will also be a structure like "Lolita Club" where a big brother leads several little girls to their goals. The male protagonist, Hibiki Kanjing, is unwilling to go to school because of the shadow in his heart. He secretly uses singing modification software to make his own songs at home to spend the time at a loss. Until one day, three fifth-grade girls who grew up together sent an email that changed everything.
