The Executive Villainess and The Justice Transforming Heroine's Sidekick

This world is under attack!
An invasion from another world, either far away or nearby.
The vanguard of this invasion are
beings whose minds and bodies have been corrupted by the magical power of the other world, and who use this distortion as their power.
In other words, “monsters.”
However, there also exists a force of justice that protects this world.
Defeat the monsters, purify the magical power of the other world, and prevent the invasion.
That is the mission of the heroine and hero of justice who have been given power by this world.
Here again, we find a hero of justice and his partner and lover, the heroine of justice!

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.
The game features survival mechanics. Gather resources by mining, foraging, logging, hunting, and fishing. Build and upgrade your base. 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.

As Scarlet’s recklessness and Lily’s cold pragmatism collide, the conflict soon engulfs the entire continent.

Capture enemy generals, turn them into allies, and clear Scarlet’s name as you fight for the duo’s happy ending!
