7-nin no Nemuri Hime

Alec, the third prince of Rudbekia, seeks to rescue the kingdom of Amaryllis and its seven princesses, who are under a witch's curse. Instead of one, he must awaken seven princesses through kisses. Though the princesses are now awake, the rest of the kingdom remains asleep. Alec and the princesses must figure out what else is needed to lift the curse, as simply waking them appears insufficient. Together, they work to uncover the full solution and save the rest of the kingdom.
