Trapped succubus

This quest activates after Lust Doll interacts with the trapped succubus in the Forest Park.

After accepting the quest, opportunity to cross on the other side opens up, by using the tree to make a makeshift bridge. After that, the only thing required to finish this mini-quest is to go across (your target would be on the north-east of the park) until you reach the cave where some fairies got succubus's tail trapped and now torture her. You just need to shoo them away. For additional scene later on you may also tease her some more by yourself.

After rescuing her, just move back and talk with succubus (who would introduce herself as Rinny) again.

After finishing the quest, you unlocks new zone – Transylvania.
