The determination of whether the novel 'Dio' is canon can be complex. It might involve factors like consistency with established lore, authorial intent, and the response from the fan community. Without specific details, it's hard to give a definite answer.
One common theme is power struggle. Since Dio is a very powerful character in the Jojo universe, when there's a female version or a female related to Dio, she often has to deal with the power dynamics. For example, she might be trying to gain power like Dio or struggling against his overpowering influence.
In my opinion, the Dio manga works quite well. The character development and the way the story progresses are well-executed. Also, the art style adds to the overall appeal.
Mr. Dior's full story did not appear on the Internet in its entirety. It may not be publicly released due to copyright or other factors. However, if you are referring to a particular novel or author's side story, I can do my best to provide you with relevant information.
One popular story could be about Dio's adventures in modern times as a cosplayer reads it. Maybe it involves Dio using his powers in a contemporary setting in a really creative way.
The main characters are clearly young Joseph and Dio. Joseph is a character with a strong will and unique abilities, especially his Hamon. Dio, on the other hand, is a powerful vampire with his own set of formidable powers.
I don't know which novel is called Mr. Dio of the Green Field Thousand Cranes. If you can provide more information or context, I will try my best to answer your questions.
