information/ introduction

I re-read the first volume. I realized that I forgot to add some plot points. there are some plot points that I didn't explore appropriately. so I want to add the stuff I let out from the first volume. I am going to add some stuff in between volume II. once I am done with that I will work on the last volume of the first Arc. I am not going to change important parts of the story, I am just adding stuff I left out and stuff that adds to the plot without taking nor changing anything important.
