Preliminary Spoiler

The Night Beyond The Tricornered Window is undoubtedly my favorite BL anime. No offense on fans of other BLs, of course. But Tricornered Window is just so good, it has horror, mystery, and boy the fanservice is just right for me. (After finishing the anime, make sure that you read the manga! The anime may feel a bit rushed, and the manga would let you understand the plot a lot better.

Mikado Kousuke is the protagonist, he's a bookstore clerk who is a literal package. He's cool, cute, shy, brave, hot, and if you read the manga, then you'd see just how much of a husband ...

Preliminary (4/12 eps)
As a fan of the manga who loves it very, very much, I'm honestly rather disappointed by the adaptation. Yes, only 4 episodes have aired, so I am hoping my enjoyment will increase since I know the plot will eventually pick up.

Story: 8
Obviously I'm biased because I read the manga so I appreciate the plot more than others and know what is to come. The general premise as mentioned by others is that two guys go around and do exorcisms and are also in the process of trying to help a detective solve a long-running murder case. There is a large element of BL in ...

The lack of information in the beggining makes it confusing, but makes you empathize better with one of the main character.

Over all, most of the episodes it's you trying to pull together all the information they are giving and trying to understand what the hell is going on, wich makes it tough to watch.

Even so it all comes together in the last episodes, making this anime very good, not only because by then you'll understand what is happening, but because if you analise it from the psicological and social part of it, and you empathize with the characters you'll understand what mental illness would look ...

Preliminary (6/12 eps)
This anime starts out... weird. Somehow even though it was very weird it captivated me and somehow made me keep watching it. To be honest i was a bit shocked after some things turned almost 'BL'. (I was not expecting that, i thought it would just be a detective kind of story.)

Due to that suprising fact it made me keep watching even more and fortunately after a weak start of the anime, it made me super interested in continueing to watch. The lore behind this was more than expected, even some small plot twists already.

I certainly can understand if someone dislikes these tyoes of anime's ...

Minor spoilers for the show.

Although I would definitely agree that the manga is better than the anime, the anime has its own charm, and it’s a nice addition to the manga, where you can see the characters move around (and in color). The anime also makes certain scenes clearer, and certain dialogue moments more understandable as to who’s talking, which makes their emotional weight stronger. There’s also at least one added scene early on that makes a character’s actions more regular than random, as they are in the manga. The music is also pretty, and the Japanese VAs all did a good job.

The anime is ...

Preliminary (11/12 eps)
Being on the second-to-last episode of the series I decided to write a review (first time in years lol) because I'm sad how mediocre the average score is for this anime.

I think the story is interesting, especially if you're into the recent uptake in demon-related action stories that are very popular right now (I totally am)! Although this is not about demons per-say, it belongs to a similar genre that's more dependent on psychological manipulation and the human soul/body and stuff. I think all of the characters are interesting and I think the tension between the two mains is interesting, actually I wish this was ...

Preliminary (3/12 eps)
For me, it's really good, I don't really mind the other stuff such as the animation, since the CG is kinda off, like in eps 2? but the plot saves it, some people might not enjoy their chemistry right now, but I think they are perfect.

I'm also invested in the supernatural part of the show and of course, in our main characters, I like them in a way that they give me butterflies, and when you have that kind of feeling it's not good, the guy (yellow-haired) is a walking red flag!!!, but what's new? I love red ahahahahahah, I also like the mood ...

My first impression of this anime was that it had to have originated as some sort of Mob Psycho 100 fanfiction. The similarities between Hiyakawa and the character of Reigen from Mob Psycho are what originally had me making this comparison. Character-design-wise, both Hiyakawa and Reigen have light-colored hair and wear gray-colored suits and both are professional “psychics,” though Reigen lacks the actual abilities Hiyakawa has. There was even a scene in The Night Beyond the Tricornered Window where another character criticizes Hiyakawa’s “fake” polished look, pointing out his cheap suit and haircut to belittle him. If I’m recalling correctly, a similar scene happened between ...

The Night Before the Tricornered Window Destiny was an extremely pleasant surprise. I am a big fan of BL anime, and went into this not expecting very much from the story or characters. A lot of BL anime are watered down yaoi, and tend to have a very weak story that mostly hinges upon angst between the main characters.

This show was an exception to that generalization. The story is refreshing and unique, centering on the occult and mediums and the powers they possess. The entire cast is well done and well-rounded, making the show as well as the ending feel fulfilling and worthwhile.

Yes, ...

Sankaku is a story about 2 individuals with some bl elements here and there. That what intrigued me at first, the bl tag, in the end it wasn’t a romance. But it was still a pleasant story with some problems

Story:
A horror bl ? Count me in ! That said the story is quite nice to follow but around the end we had pacing problems. Things were going too quick for their own good. We also had many flashbacks which made things hard to follow. The ghost stuff was also kinda difficult to understand in addition to flashbacks. The story was too complex ...

Honestly probably gonna end up being one of my favorites and not cause it's a BL but even if it wasn't, story is genuinely interesting. The supernatural and horror elements blew me away like some parts actually were somewhat scary too, but I am also just a huge pussy so its not hard but still. Honestly did not expect the animation to be this good too, honestly I really love the plot and the mystery it unraveled. It did actually entertain me and does need more recognition because the characters are likeable. I loved Erica and her bodyguard like yassss serve girlboss. Honestly all the ...

if you're looking for a sign to watch this show, here it is!

personally, i really liked the show. i gave it a watched since i heard it was BL and there isn't a lot of BL materials out there so i gotta at least try to see what this was all about.

i went into the show for the BL but i stayed for the plot and the characters. i was so invested with the show i managed to finished it in a day. ngl i was a lil "flustered", for a lack of better words, when they were a lil bit erotic with ...

Story/characters:

One disclaimer I will lay out from the get-go is this anime is in essence a yaoi series. If you are adamant about not watching such things then turn away. However, if you can look beyond that fact what you will get is an anime with a good storyline, gripping mystery and a level of character development that is not often seen in most conventional anime.

These great developments are not immediately apparent in the first few episodes though as the show goes out of its way to showcase its two main male lovers. To me that is not a bad thing (outside the crazy dialogue) ...

The Night Beyond The Tricornered Window is an anime that left a sweet and sour aftertaste as I finished watching it.
I went into it without knowing what I would expect and left thinking that it is, possibly, to this day, one of the animes with the best plot I’ve ever had the honor to enjoy.
For those of you that are into psychology, trauma and everything in between, The Night Beyond The Tricornered Window is a masterful representation of what a “core trauma” is, and what a traumatic event can cause to a young mind that is still in the making.
It’s a journey ...

I am really surprised that this anime doesn't have a higher rating. I thought it will atleast be 7.12 or around that.

Where do I start? Well this anime reminded me a little of Ghost hunt, though Ghost Hunt gave me more enjoyment but that's what this anime reminded me of but in a different way, it feels like an original story and it didn't bore me like the Yakumo anime did mainly because of the characters in this story and not just the 2 Main characters.

CHARACTERS:-I gotta say, I love the arcs of all the characters. We have 2 main main characters while ...

It took me 3 weeks to finish this anime. To be honest, the begging was a little boring, but it starts to be good after the fourth episode.

Well, first of aff, I think that the supernatural powers could be better explained. At least for me, it was confusing to understand how they worked. I didn't read the manga, but it gets very clear for me how it was rushed. I wish it could had more episodes. The anime isn't focus on romance, but you know that a relationship exists between the principal characters, it's obvious that they don't see each other like just friends. ...
