I just realized that this was never posted here, so I am rectifying that. This page is the basis behind my idea and explains what each color of the ES represents as the story progresses and his eyes change color.
This will be updated as the story goes on, but this is meant to be the most recent info regarding our character starting from Chapter 7. The top part is all info relating to our character regarding things like his currently discovered powers, age, name, current family ties, etc. So if you didn't read up till then, I'm just warning you that there are tiny spoilers.
The ES color meanings are below that.
