It all started with the death of one of the Astronomy Club's members. From this, the rumored ghost of the club came to life.

Grumpy insomniac Ganta Nakami stumbles across the moderately rebellious yet easygoing Isaki Magari in the Astronomy Club's abandoned observatory. Magari is jolted awake and tries to escape from the scene, only to have a broken door prevent that, forcing the two inside. The two forge an unlikely friendship, leading them to use the observatory as a safe space for them to interact.

Kimi wa Houkago Insomnia follows the insomniacs Nakami and Magari's time in the starlit observatory as they help each other cope with insomnia and the lasting effects it has on student life.

(TLDR at the bottom, thanks for reading.)

I'm going to start off this review with a bit of a personal anecdote of how I came to discover this manga. I was lying in bed at about midnight, trying to force myself asleep as I needed to wake up early the next day. I was tired but I just could not sleep so after about 20 minutes of trying to go to sleep I grabbed my phone (I know it was a stupid decision but I wasn't thinking straight). I decided to read some manga and after looking through the manga list of my friend's accounts and read more

“I want to sleep, but I can’t. All night long, I’m awake. This little observatory, it was our safe haven”. If you’re looking for wholesome content which isn’t rushed, this is the one. The pacing of this manga is absolutely great. The interaction between the characters is depicted in a realistic and relatable way, making this a really good slice of life manga. Just seeing the two characters open up to each other brought a fluffy feel to me. It made me realize how nice it must be to have someone who will side with you amidst your problems. The art truly brings out the read more

Story about two highschool students who share similarity as an insomniac. Its a solid story, also i personally like Makoto Ojiro art like what he did in Neko no Otera. The characters development has good pace, also the story is not rushed. Really enjoy reading this manga, i cannot give any criticism other than when i read Neko no Otera i kinda forgot what manga that i read because how similar they are. If u want to read some comfy manga, this is really a right choice to read in the middle of cold night while u get some insomnia. Kinda ironic isnt it ?

The manga is a slice of life romance about two high school students who have insomnia. The story is just really comfy, and the bits of humor interspersed makes it all the more enjoyable. The art is very well done, with characters that have facial features that you can actually recognize. You can actually recognize characters from their facial features, not hair. Backgrounds are very aesthetically pleasing, and compliments the manga very well. The little things, like the minute details on the camera, is what really brings life to the story.

The trope of the asocial male main character and the bubbly female love read more
