You know the final text of he rroute when she ask "what the Word for when you feel in your hearth that everithing in the world is ok?" Well in this au It was Hope and a blue ring choose her
For those of you that don't follow DC comics...
Green Lanterns are powered by Will Power. (It's not exactly an emotion. Take it up with DC comics.)
Blue Lanterns are powered by Hope.
Yellow Lanterns are powered by Fear (causing fear in others, not themselves being afraid.)
Orange Lanterns are powered by Greed.
Red Lanterns are powered by Rage.
Indigo Lanterns are powered by Compassion.
Star Sapphires (essentially "Pink Lanterns") are powered by Love.
White Lanterns are apparently just the best or something.
Black Lanterns are apparently already dead.
There's an Ultraviolet Lanterns but I have no idea what their deal is.
There's also a popular fancreated group called the Biege Lanterns that are powered by apathy.
Based on that, I'd make Emi a Green Lantern. I'd say it took a lot of Will to get going after her accident.
As for the art, it's nice.
