Few series have ever captured the struggles of youth as well as kimisomu does. It’s a a beautifully rendered and tender story of growth and self-acceptance.

Anime often tends to exaggerate adolescence, romanticising it and making it out to be this adventure that’s constantly exciting. The reality is that being a teenager sucks. There’s the stress that society and your parents put on you and the desire to fit in and find who you really are. It’s such a challenging and sensitive time. This anime handles that stage of life with such realism and authenticity that it blew my mind.

I absolutely loved the use of ...

I think it's a law of nature that every anime that involves astronomy or astrophotography or any astro you might think,90% of the time would definitely be a good anime and this one is one of them.

Star and celestial objects are always a good theme for making an anime, all of it on its own with decent writing could be a hidden gem but this anime goes even further and sprinkle a dash of romance that makes it level up to a hidden masterpiece.

Not only that, but it also has "insomniac" as the core of the story, Nobody likes being insomniac, lack of sleep can ...

PTSD a.k.a Post-Traumatic Stress Disorder, is a real issue that can affect all of us in certain ways that we ourselves will only know and that can be either unexplainable or inexplicable to others. But what if you could utilise the only thing that is the common denominator between two kindred spirits, and add the fraction of a relationship that's not just full of love and fluttering feelings, but one of adolescence and keen understanding? The end result will be in the form of mangaka Makoto Ojiro's Kimi wa Houkago Insomnia a.k.a Insomniacs After School, a series that, as a devoted and hardcore manga reader, ...

Preliminary (10/13 eps)

Kimi wa Houkago Insomnia is not a "bad" anime, it's just very disappointing. It turns out insomnia and astonomy were just an excuse to deliver a rather simple cliched love story (especially from episode 6) So, give it a shot if you are into cute romance, have low expectations, but don't get fooled by it's name or poster.

story:
I guess a lot of people around here can relate to the sleep-deprived aspect of the show but the writer(s) either never really suffered from it for an extended period of time, or simply lack inspiration. Insomnia can be painful, cause paranoid, hallucinations, and a lot of ...

Insomnia is something that plagues many people, and this sleep depriving condition arises from many reasons, for example, fearing what tomorrow will bring, negative thoughts, stress, and general anxiety. While insomnia isn’t something that affects me personally, for many people, seeing the two main characters who deal with insomnia, and tackle it together by pouring their restless, sleepless time into something positive like astrophotography, must have been relatable, and to me, a very solid concept. Along the way, there was some romance in the air, but it wasn’t a huge focus until near the end of the season, which I actually liked, as the characters ...

As a person who enjoys watching slice of life and romance genre, I can say 'Insomniacs After School' won't disappoint if you are searching for a comforting romance/slice of life anime to watch this season.

Nothing bad to say about the plot as it is really simple and relaxing, as it should be in these genres. Two teen high schoolers who share the same problem , in this case which is 'Insomnia' spend time together and we see them getting closer to each other gradually. The interactions between the main leads are presented well. Overall this anime depicts a growing relationship nicely . Side ...

I think it's a very fun concept because a lot of people have trouble sleeping and I've dealt with insomnia all my life basically but I don't know how to feel about this series. It feels almost a personal fantasy dream that the author is playing out for themselves, making it extremely dialogue heavy with no real direction because they're kind of forced into a club they don't personally have interest in but it's something that anyone can appreciate I guess? All that has really happen is boring small talk and the characters lack personality and charm. Series like these need strong characters or some ...

Kimi wa Houkago Insomnia is an incredible anime that had me hooked from the first episode. The story follows the lives of two high school students, Isaki and Ganta, as they navigate their growing feelings for each other amidst the complexities of their daily lives because the insomnia.

One of the things that struck me about this anime was the depth of the characters. Isaki and Ganta are both complex and nuanced because the insomnia, with their own insecurities and struggles that make them feel incredibly real. The romance of both is beautifully written, with moments of heartwarming tenderness and moments of heart-wrenching emotion.

Okay where do I start with this one?

Insomniac - a person who regularly unable to sleep.
Okay so?
The story is about a couple who both suffer from insomnia. Which maybe have messed up their regular life alots. Nakami who has publicly disclosed that he has insomnia. Everybody in class doesn't seem to care much about it. One day while doing some chore in the old storage room of the school he stumbles across Magari, a girl who is sleeping in the same room. That is when he finds out she has been suffering the same as him but was hiding it from everyone.

This is based on the first three episodes and might change after I finish the anime.
First of all let me just say that I read the manga before watching this anime so adjust your expectations for this review as its not really my first impressions on the story.Also, this review will have slight spoilers that won’t affect your experience about the three episodes so be warned.

So lets start with the story of Insomniacs after School. The story revolves around two characters Nakami Ganta and Magari Isaki who both have had insomnonia for a while and are struggling with it. They help each other ...

so this is my first time writing a review after a few years of using MAL. as someone who really loves astronomy, i can say this anime is really good and beautiful. when I saw the genre I thought this was a normal anime and when I watched it wow this is not just romance but there are some comedies, slice of life, and school genres. the last time I watched an anime with an astronomical theme was just "koisuru asteroid" then I really wanted to find another anime. and I accidentally found this anime. this really makes me grateful and happy. thank you for ...

The approach to romance in anime has been portrayed in very familiar territory. It is often an explosion of emotions, of characters explicitly realizing they are deeply in love with one another, of the exaggeration and over dramatization of love to make it “pop” for entertainment purposes. This is where Insomniacs After School takes a different, much more gentler and quieter walk on the journey of two individuals learning to understand and share their feelings with one another.

One of the first things to notice about the two leads is how notably comfortable they are around each other. While there is a presence of teenage ...

Having insomnia sucks. I can tell, because I've experienced it on certain occasions.

There are few things more unhealthy for your body than a lack of sleep. Humans are made to get enough shut eye just to recharge those batteries in preparation for the next day. This is what our main lead, Ganta, appears to be suffering from. The kid is struggling, not being able to get enough of that bedtime rest and also juggling school work at the same time. Sooner or later he comes across the school's observatory which he's told is a quiet place for him to relax in. There he meets Magari, ...

Kimi wa Houkago Insomnia delivers a simple yet effective story which will warm your heart all the while avoiding stereotypes, generic plots, fanservice overtaking the story, cliches etc. A problem I've found with recently released romance animes are they either throw you in the deep end with the romance developing in the first episode or the romance doesn't develop at all. Kimi wa Houkago Insomnia allows you to care for the characters before the romance. The romance elements make the story sweeter but it's not the stories entire core nor all it has to offer. It makes me happy to see something like insomnia explored ...

Kimi wa Houkago Insomnia is a poignant anime that delves into the complex inner lives of two high school insomniacs, Nakami and Isaki, through their shared late-night encounters in a deserted school observatory.

While some viewers might dismiss this anime as boring or monotonous, I believe such opinions stem from a misinterpretation of its thematic depth. The series excels in its grounded, realistic portrayal of adolescent struggles, exploring personal trauma and the emotional battles each character faces.

The relationship between Isaki and Nakami is exquisitely crafted. As they find solace in each other's company, their mutual encouragement helps them confront and overcome their traumas, fostering a profound ...

Insomniacs After School is much, much better than the likes of Your Lie in Apil. Why? Because it's much more grounded in reality and much less reliant on melodramatic scenes that "pull on your heartstrings" to create a compelling romance and slice-of-life show.

That's right: this show is much less melodramatic than I ever expected. Is this a good depiction of a person with insomnia? I can't say, since I don't suffer from it. What I can say, however, is that the genre of this show is mainly romance. The main couple being insomniac is more of a subtheme and a way for them to ...

A wholesome more realistic story about two struggling teens who find each other. I can imagine why some (the minority I believe) may find the show boring, but for me this show depicts feelings of finding safety love, friendship, "purpose" and healing in such a beautiful and soft way. The beautiful animation combined, shots and sound design really pull you in the world the characters live in (Aka Japan in summer time) and makes the show instantly feel nostalgic. It reminded me of shows like Skip and loafer, Hyouka and Kimi ni todoke. The soundtrack is beautiful and suprised me several times.

This is a treasure.
This is something beautiful and rare in the sea of mediocreness.
This is a warm blanket. It makes you feel warm inside.
This is Bob Ross of a show. It speaks to you softly and makes you feel at ease.
This is Yuru Camp of romance (What?).

I admire the creators of the manga and adaptation for following a clear path. I feel like they had to say no to so many things.
The mainstream romance 101 list went to trash and it's still (or rather because of that) a beautiful, touching, romantic piece of art. That's why this feels so good. ...

Speaking of insomnia, it's 4 am as I'm writing this review, so you'll have to excuse my biases when I say "Kimi wa Houkago Insomnia" has all the right vibes for a perfect SoL anime. It doesn't overly play on your emotions by giving unreasonably tragic pasts to all the characters, nor does it exaggerate adolescent romance to the point of fantasy.

The concept of the anime, combining astronomy and insomnia, plays in perfect harmony. A sleepless night can be euphoric under the light of the stars, and it's even better if there's someone to share it with you.

The character development was pretty solid for the ...

Every so often you come across a piece of medium that just makes you feel something different after watching, this feeling of emptiness that’s just so hard to describe. I’m really grateful to say that I had this feeling almost every week after watching an episode of Insomniacs After School.

In a way it really made me feel like watching Your Name again for the first time, this magical experience with beautiful starry nights in the background.

A series about star gazing and photography just asks to be aesthetic, this combined with one of the best and most wholesome romance you will find in anime makes ...
