Synopsis

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.

This is an updated version of my original review, I wrote the review below on March 20th 2023 and I've decided to update it since the manga has recently finished. The old review has since been deleted since mal won't let me have both up, although I have an archive for prosperity

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 ...

The series is about two classmates who suffer insomnia and find their refuge in a mothballed school observatory. As a school life manga it's pretty standard, one fits in with a popular clique, and the other is a misfit because of irritability caused by lack of sleep, and they interact differently with the popular girl in class.

However, it's in how the two deal with their insomnia and their unexpected chemistry that really the main draw of this title. The leisurely pace also makes it a relaxing read.

The manga portrays loneliness, trauma, friendship, and love in a touching and realistic manner. The characters have depth and ...

Preliminary (63/125 eps)

Let me start this review by saying that I understand why people love this manga. Even though I personally did not enjoy it, "Insomniacs after school" has many elements that warrant it being one of the best romance stories in the eyes of so many people.

The biggest selling point of this manga is the characters. Romance as a genre likes to include eccentric and exaggerated characters, especially if it's targeted for younger audiences, but the cast of "Insomniacs after school" feels grounded and relatable. The problems that the characters face and the ways they react to them are interesting but not overly dramatic.

My first problem ... with this manga stems from the character chemistry, or rather from the lack of it. I read romance mainly for those sweet, tense, romantic or embarrassing moments between the characters and for the way the dynamic between them develops. I like when characters banter, when they have clashing character traits or personalities. I like to feel the tension when they talk to each other. I didn't find any of this in "Insomniacs after school". Sometimes I enjoy purely "wholesome" romance too, but I wouldn't call this manga particularly sweet either. Don't get me wrong, I understand why Isaki and Ganta ended up together and I don't think their relationship is unwarranted, but a working relationship doesn't automatically make romance interesting.

The art in "Insomniacs after school" is good, at times even great. The only complaint I have is that sometimes the level of detail randomly changes between pages and even panels, for no apparent artistic reason. Although this issue got better in later chapters.

The main problem I have with this manga is bad pacing/paneling. So many scenes in this manga either drag on for way too long or end too quickly. They destroy the structure of the story and leave me feeling either bored or confused. I think the underlying plot of this manga is good, but the way it is presented ruins the whole experience for me. And the paneling only exacerbates this problem. Weird angles, awkward poses and constant zooming in on characters' faces makes reading this manga an unpleasant experience.

Very subjective problem that I have with "Insomniacs after school" is bad attempts at "show, don't tell". I think manga is a prime medium for this "rule", so i commend author's efforts to create a more interesting way to present the narrative. But because of the art style and the paneling problems I talked about previously, most of these efforts fall short. In this regard "Skip to Loafer" handles the visual storytelling of romance much better.

Overall I found this manga to be disappointing. It has great ideas and interesting characters, but falls apart because of the execution. If you don't see the problems I've written about after reading this manga, then I can understand why you might have liked, or even loved it. But I have to leave it with a 6/10.
