7 Seeds is a masterpiece. You might think that this is just another manga about apocalypse and action, but this manga is more than that. This manga is about humanity through and through.
The characters are magnificently portrayed by Tamura Yumi that I dare say they were real people and she wrote this manga based on them. Each of the character has their own equally interesting story, thus the narrative is told from multiple characters' point of view. Some of the characters may be not into your liking, however they will grow as you read, eventually you will find yourself sharing the same sentiment as the characters and you will understand why they behave the way they are. They are relatable. I have to say that the character development is exceptional. However, there is no set main character which might be confusing to some.
About the storyline, I am still in awe by how the mangaka managed to wrote something so complex but at the same time is so simple like this. Everything about this manga is well-planned, as if you were reading a historical book or a documentation of real event. Since this manga is a science-fiction, there is a lot of unbelievable stuff at first, but do not drop the book yet, it will all make perfect sense in the end.
I had hoped the mangaka would speed up the story, yet when I reread the manga I realized that there is no part that could be omitted. Many people complained about the art style, but personally, I do not mind it.
I highly recommend 7 Seeds. This manga is deep but not hard to comprehend, perfect for young adult looking for something to read after work.
