Mercy is a four-hundred-year-old vampire Arch-Duchess, and the three broke musicians who dragged her back from the dead in their basement were not what she had in mind for a resurrection. She wakes up furious, out of time, and thoroughly unimpressed with everyone involved.

The setup does the work: an ancient noblewoman stuck with modern nobodies who owe her their lives whether they like it or not. What grows out of that, between resentment and something closer to romance, depends on how you play her.

It's a visual novel built around choices and consequence, steering Mercy's temper and her interest in her accidental summoners toward one of several possible endings. No grinding, no stat sheets, just conversations that decide who she ends up tolerating, and who she ends up with.
