Take the role of an enslaved barbarian that has lost his tribe due to attack by the empire. Purchased by an infamous villainess, a high noble of the empire, you're forced to submit to her due to a magic ring binding you to her.
On an oversea journey, the ship gets attacked and the villainess falls into the ocean. You dive in to save her, and in the process, remove the ring binding you to her. Free from her control, you end up on a desert island together, where the power dynamic is now reversed. She needs you to protect and provide for her, but you haven't forgotten how she's treated you. And her haughty attitude remains. Something that you intend to address.

Craft items and equipment to prepare against the many monsters that threaten your camp. And all the while, don't forget to cook and feed yourself and the villainess.

The adult content revolves around BDSM relationship you build with the female lead that buds into romance as you live and survive together on the island. The dating sim features feeding and gifting mechanic to progress the relationship. 

In the year 2034, for reasons unknown, human genetics underwent a transformation. Upon reaching a certain age, 40% of the world’s population began to awaken to “superpowers.” The police were completely overwhelmed by the massive outbreak of super-powered criminals, forcing the government to implement a new policy to combat these offenders and their crimes.
Thus, the state established the “Superpower Academy” to guide and train young people possessing these abilities. Those who successfully complete their training and graduate are promised excellent careers! If one can graduate as an “Agent,” they will enjoy the highest status and treatment the nation has to offer. This is because becoming an “Agent” proves that one is capable of eradicating criminals for the sake of the country.
