Before reading this novel you should know that this will not be a basic novel. While many fanfiction on bleach just take the basic elements from the main story and change them, i will go deeper into the world of Bleach and of course, create some new things to make the story much more interesting.
What i mean by that, is that the main character will have a story on his own, many OCs will have stories on their own and i will change some already existing elements of the story or add some new ones to make it all logical and interesting.
For exemple, Hirako Shinji a character that many knows and appreciate. While Shinji is an important character of the manga, he doesn't really have a story of his own. We don't know much about hus past, except for the vizard accident. As such, characters like him will have their own stories in this fanfiction. Of course, i won't just randomly create his story and put it in a chapter for the heck of it, but his story will be told via many hints, and discussions with the main character or other characters, so that in the end the story that i have created for him can fit in the fiction.
Now that this is out of the way, i should tell you that the MC will most likely be completely OP. Which is normal since he knows many things about Bleach, and he's the son of the Spirit King. But don't worry that doesn't mean that everything will be solved by him in a few seconds. Because the other characters will be important and as such have their own parts in some chapters where the MC isn't present. Or just because while OP, he won't be the strongest directly.
That is all i can say for the fiction, except that there should be a chapter per day or maybe two. Good reading !
