Karen and Mitsuki have been best friends all their lives, and now that they’ve become Magical Girls, they’re even closer than ever. One day, Karen and Mitsuki visit Crio, a magical familiar. When they arrive at her house, they are immediately given a mission: to fend off the attacks of enchanted animals and fight them so that Kurio can absorb the souls and send them to Utea. Utea is the master of the magical realm, and he is the only one who can absorb and purify the souls of enchanted animals. Today, however, the two encounter an enchanted animal of the “lust” category. These tentacle-like creatures are extremely strong and full of unsatisfied sexual needs. Now, the two learn what it truly means to be a Magical Girl.
