A long, long time ago, there was a prestigious school called "Ryuuguu Elementary School" that produced many masterpiece characters. One day, an ordinary boy named Meisaku Matsuda enrolled at the school. Little did he know that the place for learning was filled with crazy characters like Sweets, the energetic idiot; Musubi, a rice ball who gets angry when called "onigiri"; Nokio, a narcissistic self-proclaimed robot; and Bolt, who's clearly faster than a rabbit. Surrounded by such unique characters, will Meisaku be able to graduate as a splendid masterpiece character? (Source: Anime News Network)

The anime centers around Kurumi Azuchimomoyama, a normal 14-year-old girl who attends Egaogaoka Middle School. One day, an angel named "Devilun" that looks like a Tasmanian devil appears before her, and grants her the power to be the beautiful magical girl dinosaur angel warrior "Prima Angel," and tells her to fight the evil "Darkness Whales" organization. She proceeds to indiscriminately take out Darkness Whales members with weapons that stink of blood. The protagonists are three boy classmates of Kurumi who watch the entire thing while not really doing anything. (Source: ANN)
