The story delves deep into the complexities of society, religion, and the age-old battle between science and superstition.

However, readers should be aware that the manga touches upon sensitive religious themes, which might not resonate with everyone.
I’ve always been intrigued by stories that blend science with fantasy, and “Release That Witch” does it brilliantly.

Blessed with immense power by the gods, he can reshape landscapes and topple nations with ease.

As he journeys through this new world, almost every female he encounters seems to fall head over heels for him, wanting to become his wife or lover. Yet, despite their overt advances, our MC remains blissfully unaware, often emphasizing his status as a virgin and blushing at the slightest touch. This creates a comedic tension as he tries to protect his virginity, lamenting his single status, all while being pursued by a bevy of beauties.
