Review Detail of Msmi in One Piece Squared

As a new Author, it is only fair to give myself 1 star, because my writing is bad. Hopefully it becomes better in the future. Just to be clear to anyone who has not seen or ignored the synopsis, this is my first time writing. So I appreciate it if anyone is willing to notify me about if there is any grammar or spelling errors. Also, feel free to give me some questions and suggestions, if the suggestion is good, I will try to apply it in the novel.
