Since I have no specific information about the 'akira novel', it's impossible to say who the author is. It could be an indie author or a well - known writer. Maybe it's a debut work or part of a long - established author's collection. Without further details, we're in the dark about the author.
There are countless web novels out there, and Akira Haruno could be a name given to a character in a niche or popular web novel. It could be a character in a fantasy web novel, perhaps with special powers or abilities. Maybe in a mystery web novel, involved in solving complex cases. Or in a romance web novel, as a love interest. But without more details, we can only guess.
Rashomon was a Japanese film released in 1988, directed by Akira Kurosawa and starred in Endo Kenichi and Toshiro Mifune. This film was created in Akira Kurosawa's later years. It was one of his representative works and one of the most successful films in Japanese film history. Through a multi-narrated story, it showed the complexity of human nature and the contradiction of morality. It deeply explored the issues of human nature, faith and law, which was deeply loved by the audience.
In the 'akira visual novel', the main character could be Akira, who might be a young and ambitious individual. There could be other important characters such as a best friend who is always by Akira's side, providing comic relief at times and moral support at others. And perhaps there's a wise old man or woman in the story who imparts important knowledge to Akira. There could also be a villainous character whose actions drive the conflict in the story, making Akira's journey more challenging and interesting.
Since I haven't read it, it's hard to say for sure. But it could feature the main characters from the original Akira like Kaneda or Tetsuo. They might be the ones being interrogated or perhaps the ones doing the interrogation, depending on how the fanfic is written.
In the 'akira graphic novel', Tetsuo is one of the main characters. He is a biker gang member who gains extraordinary psychic powers which start to corrupt him. Another main character is Kaneda, Tetsuo's friend who tries to stop him as he descends into madness.
Fanfiction can be created by a wide range of people. Anyone with an imagination and a passion for a particular fictional universe can take a stab at it.
