  • Year: 2017-ongoing
  • Chapters: 521+
Release That Witch

Synopsis: “Release That Witch” is a captivating tale of a modern man who finds himself reincarnated in a medieval world. Unlike typical isekai protagonists, he doesn’t have magical powers or a sword by his side. Instead, he has the knowledge of modern science. As he navigates this new world, he encounters witches, who, despite their immense power, face prejudice and persecution. Determined to change their fate, he collaborates with them, using his scientific knowledge to revolutionize the world and challenge the status quo.

The story delves deep into the complexities of society, religion, and the age-old battle between science and superstition. The harem element is subtly woven into the narrative, with various witches playing pivotal roles in the protagonist’s journey. 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. The isekai element is fresh, focusing on intellect over brute strength, and the harem aspect adds depth to the relationships. However, like any art form, it’s essential to approach it with an open mind and appreciate the creativity behind it.

In “Re:Monster”, the protagonist finds himself in a perplexing situation when he’s reborn not as a human, but as a goblin. But this isn’t your ordinary goblin tale. Our mc, Goblin Rou, possesses intelligence from his previous life. This isn’t just about survival; it’s about leveraging past experiences in a new world. With an RPG-like twist, when Rou consumes something, he gains its abilities, crafting skills, language, and more. As he navigates this world, he has the potential to evolve beyond a mere goblin. The manga beautifully captures the essence of survival, evolution, and the excitement of living in a harem. The art, while subjective, paints a vivid picture of the world, making it easy for readers to immerse themselves in Rou’s journey. With a cast of intriguing characters, “Re:Monster” offers a fresh take on the isekai and reincarnation genres.

I’ve always been a fan of isekai manga, but “Re:Monster” stands out with its unique premise. The idea of leveling up by consuming and learning is both intriguing and innovative. It’s not just about being reborn in another world with women all around; it’s about adapting, growing, and evolving in unexpected ways.

Chronicles of an Aristocrat Reborn in Another World manga cover


“Chronicles of an Aristocrat Reborn in Another World” introduces us to a protagonist who is nothing short of a prodigy. Blessed with immense power by the gods, he can reshape landscapes and topple nations with ease. Yet, instead of harnessing this power for grand technological advancements, he spends years learning from elites who possess only a fraction of his strength. The magic system, while seemingly straightforward, doesn’t challenge him, allowing him to cast spells effortlessly. The art is commendable, showcasing the work of an experienced artist. However, the characters, especially the side ones, might feel a bit generic. The main character, despite his overwhelming strength, often comes across as passive, making it a challenge to connect with him.

As an isekai enthusiast, I’ve come across many tales of protagonists reborn with unmatched power. What intrigues me about “Chronicles of an Aristocrat Reborn in Another World” shows the contrast of immense power with a seemingly passive protagonist. It’s a reminder that strength isn’t just about physical might but also about the choices one makes. The harem elements add a layer of complexity and make it more interesting.

Off to an Invincible Start


“Off to an Invincible Start” introduces us to a fresh concept in the isekai genre. The protagonist, while possessing immense strength and capability, is ironically dense when it comes to understanding the affections of those around him. 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. While the story offers a refreshing take on the isekai-harem blend, some readers might find the protagonist’s obliviousness more frustrating than endearing.

When diving into “Off to an Invincible Start”, I couldn’t help but chuckle at the irony. Here we have an MC who’s practically invincible in every sense, yet when it comes to love, he’s as clueless as they come. It’s a delightful mix of power fantasy and romantic comedy, making it a must-read for fans of both isekai and harem genres.

Trapped in a Dating Sim The World of Otome Games is Tough for Mobs


“Trapped in a Dating Sim: The World of Otome Games is Tough for Mobs” is not your average isekai harem story. While it has the foundational elements of being transported to another world and surrounded by potential love interests, what sets it apart is its protagonist. Unlike most isekai tales where the main character serves as a relatable self-insert for readers, this manga’s hero is distinctively unique, bordering on being a psycho.
