Dark Moon: Tsuki no Saidan

Ever since she was a young girl, Sooha was told to hide her superhuman abilities to avoid getting mistaken for a vampire. Having been accused of being one and blamed for her childhood friend's death, Sooha enrolls in Decelis Academy—a night school where supernatural beings, such as vampires and werewolves, allegedly cannot enter.

At the academy, Sooha soon encounters Heli, a student who offers friendship despite discovering her secret. Heli introduces Sooha to his close friends—Jaan, Jino, Shion, Jakah, Noa, and Solon—who all have different powers as well. But their connection seems to run deeper than just that; they are curiously drawn to her, feeling as if they would do anything she wishes.

In light of a recent murder that is said to be the work of a vampire, Heli and his friends' unsettling history slowly unravels. While the seven boys try to shield Sooha from the world of the supernatural, she inevitably gets entangled in the centuries-old rivalry between vampires and werewolves. As tensions intensify, Sooha realizes that she may be closer than ever to the creatures she hates the most.

I ultimately liked this anime but it was heavily carried by the male characters good looks.
The art style is very nice and the storyline is fine however the ending was a bit unsatisfying. The plot was a little slow, good in theory but I wish it was a movie or more detailed in the plotline and character arcs.
Despite being super strong and tough, the female lead does nothing to defend herself even though she totally could, which feels like a lost opportunity.
Overall i enjoyed the anime but it was mostly based on vibes and fanfare and i am a simple minded viewer.

Meter your expectations for this anime. It's Twilight and Vampire Knight mashed up, but Dark Moon is inferior to both. Vampire media is oversaturated, and anime is no exception. Vampires will always hold a special place in my heart, but I wouldn't rewatch this slop if I was paid to do it.
Halfway through, there is little to no explanation of the supernatural lore. The story is mostly fluff and very little plot. Then, all of a sudden there's an actual story beyond the slice of life school dynamic, but it's so weak it's pitiful.

Reverse harems are only interesting when it isn't immediately obvious ... who the MC will choose. I can't fault Dark Moon too much for this, as most reverse harems aren't executed well in this regard. There are also too many characters. While they all have distinct, stylish designs that make it easy to tell them apart, the viewer doesn't get to explore much character development when there are so many of them.
No one has a personality, except for Solon because he's a bit grumpy- they were trying to make him a tsundere, but abandoned it halfway through. And maybe Shion because he's a little more bubbly and extroverted than the rest.

The MC, Sooha, is incredibly dense. She ignores evidence every episode, choosing to give people she hardly knows the benefit of the doubt in an increasingly dangerous world. She hates vampires, so she should be more cynical and discerning, but she remains an idiot. When the backstory comes to light, she's still super vanilla, nothing can make that girl interesting.

There are no real stakes in this anime. It's fluff masquerading as an actual plot, the danger is fleeting and the good guys are healed instantly in the face of danger. It's a shame, because the climax of the last episode had potential, but it was already bogged down.

Going into this, I had no idea what I was about to watch. I assumed it would be something like Twilight or a typical supernatural romance. I only found out recently that it’s actually based on the story of a K-pop group, and once I learned that, a lot of things started to make more sense in terms of how the characters act and why the story focuses so much on them as a group.

The pacing is very strange. There are too many characters and most of them don’t get interesting development, so it’s hard to really care about what’s happening. The most interesting part ... is the twist where they reveal the truth about who they are and Sooha’s role in the story. That was probably the moment where the show actually became interesting and then it went back to being bad.

The biggest problem is that the series doesn’t seem to know what it wants to be. Sometimes it feels like a romance, sometimes like an action story, and sometimes like a supernatural drama, but it never fully commits to any of those ideas. Because of that, the story feels messy and unfocused. I also think this could have been a much better and more solid story if it was shorter, maybe four episodes instead of a full season.

I finished it only because I don’t like leaving shows unfinished, but I can’t really say I enjoyed it.

★☆☆☆☆ (2.5 / 10)
