( When the aura begins to form, Esikko finally slips out of that tired looking frown and into a small little smile. Maybe whoever taught Hiyori this said it wasn't magic, maybe they don't consider it such, but— he reaches his free hand out to run through the sparkles, useless in everything except gesture. Like pressing a hand through a ray of sunlight itself, and just as warming. )

This is most certainly magic...

( His voice is soft, though, fond, and he lets his hand rest back down, the other one still nestled easily in Hiyori's hold. )

To me, anyway. Magic varies from person to person, so it makes sense that any sort of projection you create would be unique like this. Hmm, what does it use... Does it take some energy? A little bit of stamina, perhaps?
