"Azuchi Momoyama Kurumi" is an utterly ordinary middle school girl. One day, she is suddenly chosen by the angel "Devirun" to become the beautiful magical girl dinosaur angel warrior "Prima Angel," and is forced to fight against the evil organization "Dark Whales." Wielding an absurdly blood-soaked arsenal, Kurumi purges enemy after enemy. And standing by and doing nothing but watching the whole thing are the three boys (the protagonists). https://www.youtube.com/watch?v=4_KIW3uBaWE
