Premieres sometime in 2026. Check out the Crunchyroll article for additional information. Synopsis from AniList:
In the year 199X, the world is engulfed in a nuclear inferno! The seas have vanished. The earth lies in ruins. It seems all life has been wiped out...but humanity has not perished!
Across the scorched and broken land, survivors cling to hope, desperately searching for food and water. However, their hopes are trampled underfoot by violence. Might makes right in this world, and the weak are crushed without mercy.
From the depths of that despair, a lone man with seven scars on his chest emerges. His name is Kenshiro, heir to the legendary assassination art Hokuto Shinken. As he roams the wasteland in pursuit of his sworn enemy Shin, who stole his fiancée Yuria, Kenshiro answers the cries of the oppressed, becoming a beacon of hope in a world of despair.
Standing in his path are brutal survivors of the apocalypse, their ambitions twisted by power and greed. In a world where the weak are prey and prayers go unheard, Kenshiro forges a path with his iron fists!
Well, I hope the anime has an art style that looks like this and also isnt a fully 3d animated work. Trigun's new art style was a big disappointment for me.
