thinking about making my own manga

The basic concept is that a rogue in 2090's San Francisco, United Earth (yes earth is united in my story) started making adjustments to his biology and enhancing his physical capabilities with cybernetic prosthetics and converting his brain slowly into a computer to defeat the mega corporation Ryotech, the actual physical setting is the entire solar system with colonies and cities on Mars, Venus, Mercury and all moons. With several massive orbital star stations in between them. I'm still writing out the main character but his name is definitely Yirō Shina
