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 is not great. It could have been a lot better than it is, but it doesn't explain its world well enough nor give itself time enough to cook through. What it is though is compulsive viewing, it has a soap-opera quality to it where you want to see what happens next, even if you know it's not going to be good.

So don't think too hard about it and just slide on through.

If you want to think about where it falls down (and I wouldn't bother...), then it sets up a dark fantasy world with elements of the tedious "don't ...

< concise review >

Verisimilitude: The "lifelikeness" or believability of a work of fiction.

Well, in Seven Spellblades, this is not the case. Something just feels "off". Character interactions feel forced and cliche. The script is boring, idiotic, and campy. Character expressions fall flat. And thus the show fails the believability test. This is sad, because on paper this should have been a fantastic show. But the people who put it together just didn't know what the flying f**k they were doing.

The worst part of the writing is the transitions. Switching from grimdark to happy-go-lucky friendship slice of life time is entirely possible to ...

This series is a bit of a mess as it lacks focus and isn't sure what it wants to be

The Harry Potter comparisons are apt, but clearly in an attempt to avoid those comparisons the series tried to add in all these extra elements and became an even bigger mess than Harry Potter is.

It's a magical high school romp, except they are either skipping class a lot or the school just doesn't do more than two classes a week.
It's a revenge story, except the MC doesn't seem to have much interest in carrying out his revenge
In an overall story premise that makes little sense
The school ...
