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.
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'.
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.
For a book of 457 pages, if you read the same number of pages every day, the minimum time to finish the book in a few days depends on your reading speed. Generally speaking, the average person's reading speed was between 10-15 pages per minute, so it would take about 7-10 days to read 457 pages a day. However, if one's reading speed was faster and could read more pages per day, the reading time could also be shortened. Therefore, the specific reading time needed to be judged according to the actual situation.
Typically, light novels can be recognized by their relatively fast - paced storytelling. They usually have a good balance between dialogue and description. For akira sakamoto's light novels, if they are like most in the genre, they may have engaging plot twists and characters that readers can easily empathize with. This can make the reading experience exciting and immersive.
