As the Villainous Saintess, I’m working Hard to Save the World Again today

After being reborn, Noi discovered that she had become the final boss in the RPG game The Song of the End — the World-Ending Witch, Vielrich. Imprisoned by the Church as a dangerous saint, the one assigned to “guard” her was none other than the original game’s main protagonist, the one known as the strongest hero: Light Montis. So dangerous—she mustn’t reveal even the slightest flaw! Thus begins the romantic battle of wits between a transmigrator and a reincarnator.
