Trailer: The Night Beyond the Tricornered Window


Shy bookstore clerk Kosuke Mikado has the ability to see ghosts and spirits, an ability he wishes he didn’t have since what he sees usually terrifies him. Rihito Hiyakawa, an exorcist whose supernatural powers are as strong as his social graces are weak, doesn’t seem to fear anything, mortal or otherwise. When this odd couple gets together to solve the bizarre cases that come their way, their work methods may not be entirely safe for work!


Rating: 3 out of 5.

The interaction between the two main characters can be quite funny, sarcastic even and at times confrontational and intense. This is the reason why this anime is both entertaining and engaging. There’s a lot to take in also – given the investigations into the paranormal.

While you may remember investigative-detective animes or even movies, this BL series is quite original. The episodic investigation will show who the main characters are. The music can drive you nuts, especially during suspenseful scenes – and there are plenty.
