Succubus Heaven

The era when Imma began to appear from people.
As the miasma erupted in the central part of the continent, the battle between the Imma and the demonic masters became more intense.
It was clear to everyone that it was a fleeting peace, though a dangerous balance was maintained by the pre-disaster relic "sanctuary".

During that time, sanctuary abnormality is confirmed at the ruins of the continental frontier.
Three of them were the witch Eleonora, Serra, and Dorothy, the other witch.
There is no time to wait for more cheer.In order to restart the stopped sanctuary as soon as possible, we had to challenge with just three people to the dungeon where miasma is rampant.
