Each character is a descendant of legendary beings—vampires, elves, amazons, gorgons, sirens—wielding ancient powers tied to the Greek gods. The goal is to gather fragments of the Moirai Seal, a forbidden artifact that can control fate itself.

With strategic deck-building, players engage in intense, tactical battles, using cards for attacks, defenses, and unique abilities. Only the strongest and most cunning will conquer the Waifu Wars and claim the power of the Moirai.
