Well, the novel has its own charm. If you enjoy in - depth descriptions, long - winded character development, and using your own imagination to picture the world, then the novel is a great choice. It allows for a more immersive experience in terms of the written word.
The art style is a major difference. In the manga, the visuals directly show the characters and the post - apocalyptic world in a very detailed and often dramatic way. In the novel, the descriptions are more text - based, leaving more room for the reader's imagination. Also, the pacing can be different. The manga might need to condense some parts for the sake of the visual storytelling, while the novel can take its time to develop the plot and characters more thoroughly.
Honestly, no one knows for certain when the Seraph of the End manga will conclude. It could be a while, or it might wrap up sooner than we expect. The best we can do is keep following the updates and hope for some clarity from the creators.
