I just realized something. Everyone except for Imtalia are all colorful. Which wasn't intentional, but it might as well have been. During the events of Jeurosho, it takes place millions of years in the future, and Earth is a non-stop Hellzone of survival and intense heat. Meanwhile, Jeuroshoians are (mostly) living a normal life. Imtalia's clothes being faded and worn really show just how fucked Earth has gotten. I mean, she's young and her behaviour reflects this.
