The school has been infested with succubi, and it's up to C-Cat (real name: Aki Maejima) to save all her classmates! But the demons have a secret weapon... a powerful succubus literally borne to destroy superheroines like her! With her Crystal Heart shattered, does C-Ct have any chance of saving her friends? Or will she give in to the pleasure and become just another cumdump for the Kingcubus, the lord of all that is hard and horny...?
