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 ...

This anime is the least gay BL I’ve ever seen, but it’s also one of the most interesting.

The main draws of this show, to me, are the mystery elements and supernatural themes. The Night Beyond the Tricornered Window maintains a surprising amount of suspense in each episode, with well-edited sequences and a sinister atmosphere. While watching, I often found myself impressed by how tense certain scenes could be; Tricornered Window stands out among other BL anime for being quite competently directed.

The characters also develop pretty differently from other BL stories. Much of the focus is placed on how the characters’ psychic powers affect their interpersonal ...

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 ...

This is probably one of the few anime I've seen that I can't tell if I like it or not. I do appreciate a BL when i come across one and often find them either being creepy or cute, sometimes even both, as odd as that can sound. This one was a very hit or miss in my opinion. For the short summary, do I think you should go out of your way to watch it? No, not really.

please remember, this is purely my OPINION. Do not feel obligated to agree with me, you like what you like.

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 ...

i was so ready to hate on this, and after 4 chapters i was calling it "mob psycho if it was writed by a 15 YO that only consumes BL", but i kept watching because i was interested in the paranormal aspect of the series, and i'm glad i did, because i enjoyed the rest of this, but man , for context i've never seen nor i'm interested in watch a BL Anime, so i started watching this not knowing that, and i cringed at the fan fic/doujin level of dialogue this had, i was ready to call it, and leave it after one episode, ...

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 ...

I'm not a fan of BL/Yaoi nor its counterpart of Yuri/Lesbian-made works, but I do know how to spot a good show if the source material is ever that good. And alongside the much superior Mieruko-chan that aired together at the same time, Sankaku Mado no Sotogawa wa Yoru a.k.a The Night Beyond the Tricornered Window was in overall stance, a rather "complete" but incomplete, cheap and poor adaptation of Tomoko Yamashita's BL manga that's still the superior version of the source material.

The supernatural, paranormal, mystery BL story lies within the context of 2 guys: Kousuke Mikado and Rihito Hiyakawa. The former being Mr. Triangle ...

For shows like these, no matter the concept and story telling. If you're going to have a duo lead the line, then you best make sure that they mesh well together, and can really push the show forward. In this case, it falls flat and misses so many marks. If the characters don't mesh together, or the chemistry is seriously lacking. Then certain scenes are going to be left awkward, and uninteresting by default. If you wanna see a better driven BL kind of show, then you are in the wrong place, and it would be better to watch something else.

Now that's not to say ...

Not gonna lie, i thought this is gonna be pure BL since its been recommendable recent in fujoshi community. But i think its kindddd offff fair but kindaaa off not. I will say this, its SUPER DUPER GAY in ONLY just in the beginning but it kinda slowly show that no, this is NOT BL.

If you watch for like 1st few episodes, yes this is about 2 men who just happen kinda look sexually exorcist some bad omen / spirits. I think THATS why it look like BL. Its kinda a waste and a bummer cuz imagine people watching this are not fujoshi, they'll be ...

I'm gonna say it - it's hardly a BL. It really doesn't feel like one, and I'm not sure if I should be angry at the queer-baiting, or disappointed it doesn't use the source material better.

I entered this anime with no ideas whatsoever. I was told it was a BL, I saw the trailers, and that was it. I thought it was a great concept and I was excited for a BL with an actual plot alongside their relationship.

First off, if you don't know the manga, you'll be pretty confused. There are scenes that are awkward and quiet, and overall the plot couldn't ...

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 ...

I'll give credit where it's due in that there's not many examples of a BL & supernatural genre crossover nowadays, which is a pity because when it's done right it can be so good but here we have a below-average production. The pacing of each episode is so fast there's never any room for the plot or character development to breathe. The sexual component of the exorcisms is an interesting addition but comes across as more comedic and awkward rather than erotic, again a side-effect of the show's terrible pacing that fails to allow any tension to build up. At three episodes in I have ...

Ok so just for context, I haven’t read the manga and I went into this with absolutely no idea what to expect.

I won’t go as far as saying this anime is bad. I am only 4 and a half episodes in at the time of this review so to be too critical as of right now probably isn’t justified. With that being said I really only have continued watching this far because I feel that they’ve done a really great job setting up a world with potentially interesting characters, story, and supernatural abilities.

Now, to get into why I think this anime is struggling ...

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, ...

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 ...

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 ...
