Only just noticed the interesting contrast between Hiro's earrings and the protagonist's. She has rings where he has dots, and vice versa. It's almost like a physical representation of yin and yang, and that dichotomy applies to their personalities too, with her being much more direct and bold compared to his roundabout, restrained persona. Their interactions are fun so far, and I have a feeling there's a lot more in store for the two of them, especially if this was an intentional design choice and not just a silly little coincidence.
