After being tricked into participating in a ritual to resurrect an evil god, the candidate for sainthood, Liruna, must seek out the four Sealing Orbs. It's up to Liruna to end the ritual and save herself... and her world.

Taken in by the church, Liruna has been training to become a saint. Unfortunately, when her father passes away, the role is instead given to one of her fellow trainees, and Liruna is tasked with taking part in a whole different kind of ritual.

However, her misfortune doesn't end there. The ritual goes terribly wrong, resulting in a curse and a meddlesome succubus being freed alongside an army of monsters that have been sealed away for centuries! To make matters even worse, members of the church are kidnapped and imprisoned all over the world!

It's up to Liruna to find the four Sealing Orbs to prevent herself from succumbing to the terrible curse the succubus laid upon her and put the monsters in their place! Join Liruna in her quest to save herself and her world!
