I'm not sure specifically as I haven't read it. But generally, a graphic novel combines visual art with storytelling. 'Sonne und Beton' might be about various themes like urban life (since 'beton' means concrete in German, could imply an urban setting) and perhaps something related to the sun which could symbolize hope, warmth or new beginnings in the context of the story.
Since I'm not familiar with this graphic novel, it's difficult to determine the main characters. However, given the title, there might be characters who are either trying to escape from a cold, concrete - like existence (represented by 'beton') and are drawn to something symbolized by the sun, like hope or a better life. Or perhaps there are characters who are part of a world where the sun and the concrete play important roles in their daily lives and personalities.
I'm not entirely sure if there is a specific 'naruto is escanor fanfic' out there. It depends on the creativity of the fanfic writing community. Some writers might be interested in exploring how Naruto's personality and abilities would interact with Escanor's, perhaps in a scenario where they meet in a different dimension or something. But you'll have to do some searching on the major fanfic platforms to be certain.
Indeed, Escanor's death occurred in the manga. His fate was a significant plot point that had a big impact on the story. It was a poignant moment that added depth to the narrative.
One great 'Merlin and Escanor' fanfiction is 'The Bond Beyond Kingdoms'. It beautifully explores their relationship in a world where they have to team up against a common magical threat. The story delves deep into their individual powers and how they complement each other.
One great Naruto and Escanor fanfiction is 'The Unlikely Alliance'. It combines the ninja world of Naruto with the power - filled world of Escanor from Seven Deadly Sins. In this fanfic, Naruto and Escanor meet due to a strange rift in dimensions. Their different yet equally strong personalities make for an interesting dynamic as they face various challenges together, including powerful foes that neither of their worlds has seen before.
I really like 'Escanor and Merlin: A Different Path'. In this fanfiction, the author takes a unique approach to their relationship. Instead of the typical interactions, they are put in a situation where they have to rely on each other in a completely new way. It's full of adventure and the development of their bond is very well - written.
