It depends on your perspective. Berserk is definitely dark, with its violent and tragic storylines. But some might argue there are other mangas that could be equally or even darker based on personal preferences.
😋I recommend the following novels to you:
1. "Days of Escorting in the Central Plains." The main character of this funny martial arts novel was a young man who had dropped out of school. He had the dream of fighting for justice with a sword, but he was troubled by daily necessities. Ranking index:
2. "Traversing the Huashan Sect: The Unlucky Man's Reversal" was a humorous and lighthearted wuxia novel. The plot was different from traditional wuxia novels, and it made one feel happy after reading it. Ranking index:
3. "Green Bag Records" was a traditional martial arts novel. The main character was a young man who wandered the Jianghu after losing his memory. He gradually grew up and revealed the plot of evil forces. The writing style was rigorous and logical, but it was relaxed and humorous. Ranking index:
I hope my recommendation is helpful to you. If you like it, go and take a look, or you will miss the wonderful content~
One of the darkest Marvel comics is 'The Punisher MAX'. It delves deep into the gritty and violent world of Frank Castle with very intense and disturbing storylines.
Well, for a manga to be the darkest, it often features a lot of hopelessness, a cruel and unforgiving world, and characters facing constant and overwhelming hardships. Also, the art style might contribute, with heavy use of shadows and dark colors.
Hellboy has its dark moments, but it's not unanimously regarded as the absolute darkest. The perception of darkness varies from reader to reader, and other comics might push the boundaries further in that aspect.
