Kagi no Kakatta Heya is an episodic drama about the locked room mystery cases that are encountered by our 3 main characters: Enomoto Kei, Aoto Junko, and Serizawa Gou.

From all the detective series that I have seen so far, the unique thing about KagiHeya is that it doesn't aim to make you think about who did the murder. It's actually easy to pinpoint who's the killer because they tell it to you. However, figuring out the trick is the difficult part. So even though you know who did the crime, you'd still be kept at the edge of your seat until the end.

I gave 10 in almost all aspects. It's a subjective matter and to be truly honest, I really loved everything about the drama. While it is a certified cliffhanger (even with the SP!), I love cliffhangers so I'm still giving it a 10 for the story. The 3 main characters have different personalities, but they indeed make a great and interesting team. The actors portrayed them perfectly too. I'm still not over how Ohno portrayed the robotic, weird, and mysterious Enomoto Kei. Lol.

The music was really amazing. The OSTs added so much to the suspense and mood of the story. And Face Down? I've been playing it on loop hahaha :D a great song, really!

Rated it a 9 for the rewatch value, though, because the suspense decreases as you rewatch it. Although I may watch it some other time because I'm slow at understanding the tricks! Lol.

Anyway, if you love mysteries and detective stuff, I highly recommended KagiHeya! :D
