The second dimension life starting from Fuyuki City

I, Mo Yi, am known as Master Yakumo in the martial arts world.
But I have some troubles recently——
First: The system finally allowed me to become a good writer, but the editors refused to sign me when they heard the name of Master Yakumo. The problem is, I really want to become a good writer, but works like "5 Centimeters per Second" and "One Piece" sound like serious works!
Second: My sister, Erina Nakiri, was the final boss of the other world that I defeated in my previous life. God always wanted to kill me and take back her godhood. However, God's godhood had long been turned into a system by my clumsy hands. I was also very desperate!
Third: The teacher asked me, who makes millions of dollars every minute, to join the ministry because I was late. But what I like to do most is to say NO to those who think they are right.
Fourth: On the way home, I met an arrogant blue spearman. I had a bad temper and knocked him away with one staff, but that caused even more trouble.
Fifth: I get to know more and more (female) friends, for example, I always pick up white rebbe hats, pet girls who can’t take care of themselves, and so on.
