High schooler Ganta Nakami has trouble falling asleep most nights. As a result, he is irritable at school, always searching for an opportunity to find a secluded place to doze off. On the other hand, Isaki Magari is a free spirit who is well liked by her friends, but no one is aware of her sleep disorder. She makes use of the school's abandoned astronomy club observatory as her secret sleeping bunker when she needs to get some shut-eye.

As fate would have it, Nakami finds Magari napping in the observatory. When Magari discovers that she and Nakami have something in common, she offers to share her secret sleeping spot with her fellow insomniac. As the two find warmth in each other's company, the struggles they face start to become easier to confront.

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 ...

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.

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.

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 ...
