Mel always found the apocalyptic Gacha World of the 'Witchhunter's Howl' quirky and confusing. The Tragic Witches. The over-powered Saintess. The Bad Ending. And the twelve thousand Dollar she spent on pulling PNG waifus. Really, another salary emptied? Aw, she still hasn’t bought the new, limited merch yet!But now, transmigrated back to the world 15 years before the apocalypse, Mel had a new mission: as the Witch of Lust, she had to seduce the six other witches, plus the Saintess, to prevent the end of everything.Now if only the Kingdom would stop mistaking her for a terrorist, her childhood friend-turned-lover Envy would chill on the yandere vibes, and the Saintess wouldn’t tease her every chance she got...“Ah... I want Miss Pride to be my chair at my tea party...” Mel sighed, just another normal thought on another not-so-normal day.
