In almost 6 years in this manga/anime universe, I sincerely believe that this manga was the 1st to break my heart so much. Whatever the aspect, I think Horizon is as close as you can get to a masterpiece.
On a technical level, it was simply breathtaking. You don't need a word, a name, a time or a place to feel the despair, the fear, the sadness, the anger that the boy feels right up to the end of his story.
The drawings, simple but so expressive, accompany the brutality and cruelty of the story with gentleness, delicacy and finesse. Even if, by the grace of God, we've never lived through these horrors, we can only sympathize and accompany the boy and girl as best we can in this atrocious, barbaric world, leaving nothing for anyone.
Despite the various moments of happiness and peace, these were unfortunately all too short-lived. Absolutely nothing spared our little protagonist, and that's what makes it all the more tragic.
Nevertheless, despite all this, we must keep the faith and fight to survive, because one day, all this will come to an end and we'll be able to find love and peace in our Garden of Eden in this hell.
If you think your shoulders are strong enough, I strongly advise you to read Horizon. It's an unforgettable experience.
