How to write manga?
You really have to write down your entire plot down on to paper–what you specifically want to happen in each chapter, how you want each character to be introduced and developed. First, make an outline of your plot. Write down all of your ideas on to a piece of paper. This will help you organize your thoughts and give you the basis for a solid plan. Develop it. Decide what exactly you want to do with your story. Look over your ideas, tweak it. Develop a clear story. Write it all down in detail. Then go through it and break it up into chapters. Write write down specifically what you want to occur in each chapter, and make sure that you aren’t dragging a subplot on too long or too quickly. Then you’ll want to write up an outline of each character. Write down their personalities on papers, and how you want to gradually develop them throughout the series. Check and recheck your plan. Over and over. Ask others to look it over. Make sure you have no plot holes or parts that don’t make sense.
