Here's the aesthetic for some of the more important characters in the story. Now please bear in mind those are not by any means professionally done. I made them myself mostly because I found it fun to show you what kind of images I have in mind while I was writing the story. 

I know their artistic value is rather poor but I like them anyway ^^
