This story is a rewrite of an 5 year old fanfiction. It was one of the first things I've written. The story, plot and idea of the book remains the same while I use my improved author skills to re-arrange events and give the book better writing style.
When this book was first written, Bakugo was one of the most hated character in the show, constantly being bashed in different fanfictions. But I always liked the character so I wrote it about him. Even before, it was not a true reincarnation fic but a slightly altered Bakugo that had his good parts while toning down his flaws.
Expect an altered Bakugo. But like any change, it will be a gradual process. While he is a child, he will act like what you would expect from kid Bakugo. But as his age and as the story progress, the small change at the start begins to make big differences.
Expect some butt clench, action, jokes that are sometimes funny and not funny and a powerful MC. Romace will be there and different love interest will be presented but that would not be the main focus. The original one focused on different love interest but it wasn't a harem because I tried to make it so that the readers can imagine who they like to end up with Bakugo at the end of the story.
The plot, much like Bakugo, will change gradually until it is barely recognisable. It may remain similar until the tournament. At least that's how it was before.
I don't know if these decision will change or even if I will go further than the original story of this fanfiction, but that's what you should expect.
