Under normal circumstances, copying homework is a violation of copyright law, while copying comics and novels may constitute copyright violation.
In novels, plagiarism can lead to copyright problems because novels are usually copyright-protected works. If you plagiarize a novel, manga, or other work, it will constitute an act of copyright and may cause losses to the original author.
In the case of manga, plagiarism could also lead to copyright issues. Comics are an art form protected by copyright. If you plagiarize a comic, it may be an act of copyright violation.
Therefore, copying homework and copying comics and novels were immoral acts that could lead to legal issues. If you want to borrow or quote someone else's work, it's best to obtain the original author's authorization or pay the copyright fee before using it.
