The 'Sakamoto Days' novel is mainly about a former top - tier assassin named Sakamoto who has retired and become a fat, unassuming man. But his past catches up with him, and he gets dragged back into the dangerous world of assassins. It's full of action, interesting characters, and unique fight scenes.
The main character is Sakamoto, of course. He's the ex - assassin. And there are other assassins who play important roles as well, like Shin. They interact with Sakamoto in various ways, either as opponents or sometimes as reluctant allies.
Sakamoto wasn't the main character of an anime. He was a ninja in Japanese history, and was known as the " God of Ninjas."
If one had to say that the male lead of the anime was more pretentious than Sakamoto, it might be Tanjiro from Ghost Blade. Tanjiro was an ordinary person, but he always displayed amazing strength in battle. It could even be said that he was pretentious. He constantly challenged strong enemies to improve his skills and was not afraid of any difficulties or challenges. His image was very much in line with the definition of the word 'pretentious'.
I don't have enough information to say exactly who Miu Sakamoto is in this context. They could be an author, a storyteller, or someone involved in creating this 'never ending story'.
The 'Haven't You Heard? I'm Sakamoto' manga and anime have a lot in common. The anime follows the main plotlines and character developments from the manga closely. However, there are some small changes in the order of events or the emphasis on certain scenes to make it work better in the animated format.
Overall, the anime of 'Haven't You Heard? I'm Sakamoto' does a decent job of representing the manga. There are some visual differences and minor tweaks in the plot for better animation adaptation, but the core remains the same.
The story of '91 days' mainly revolves around a man seeking revenge. He returns to his hometown which is controlled by the mafia after a long time, and he has a carefully planned revenge plot against those who wronged his family in the past.
Sakamoto and Kouta are likely characters that fans have created a relationship for in fanfiction. They could be original characters, or perhaps characters from an existing series that the fanfiction writer has chosen to pair up in a new and creative way.
