In order to create the Ultimate MC, I became Soldier A!?

Hello, my name is Yukimura Shin. I used to be a mangaka for Shounen Jump, but I was fired all of a sudden one day. Why? According to the editor, it was because my MCs are always too “2-D.” What am I supposed to do then??? Unemployed and desperate, I was offered one last chance. A chance to observe and create the ultimate MC. “In order to create the Ultimate MC, I became Soldier A!?” *Note: This fiction is episodic and a light-read. Pure non-sense. Please do not proceed if you are one that puts an emphasis on plot, as this will be similar to Gintama (completely crazy, I would say).
