Impressed by Nanao Hibiya's skill with a sword, Kimberly Magic Academy instructor Theodore McFarlane saves the samurai from certain death amid a fierce battle. With his encouragement, Nanao enrolls in the academy, where she instantly becomes a celebrity after she and four of her peers save a student from an enraged troll. Under the leadership of Oliver Horn, a young man who seems to hide a troubled past, Nanao and her newfound friends start their magical apprenticeship at Kimberly—where only four out of five students make it to graduation in one piece.

It does not take long for Oliver and his friends to experience the dangers of the academy firsthand, as a near-death encounter in the labyrinth under the school leaves Nanao grappling with her bloody past. The inexperienced yet determined students must stick together if they want to have a chance to survive and uncover the mysteries that the academy holds.

Nanatsu no Maken ga Shihai suru, or Reign of the Seven Spellblades, if you prefer, is a great show that takes its time to develop itself. As an adaptation of the LN given a runtime of 15 episodes, it did a pretty nice job at what it was trying to do. That being said, it wasn't able to be as indulgent as the LN but what it does provide is enough to satisfy what it does cover in the story without leaving too many things undeveloped. That being said, the "3 episode rule" many people follow does this show a disservice. The suggested minimum episode ...

Nanatsu no Maken ga Shihai suru (2023)

Overall, it is like a 7 but it has a massive issue. This isn't supposed to be the power of friendship and slice of life, it is supposed to be dark, gritty, and full of revenge. It was supposed to be deep but in the end, it is Harry Potter with more selfish characters. People hide their powers when it matters and you get a deep set of allies everywhere but they basically do nothing.

It has a lot of ideas and it tries to do a lot of things, many of which could have worked: after all, it's basically 'Harry Potter', only darker and more violent.

It's an awkward mess from start to finish, entertainingly bad at times, but mostly just boring.

It is immediately clear that the series is drastically abbreviating its written source material, and whatever appeal the original may possess, ...
