Aya is more than happy to follow Kaiko's suggestion that they go outside, because she loves the feeling of the sun on her back and the fresh air being absorbed by her skin when she is outside. While there is nothing particularly wrong with enjoying the indoors, such a preference has never been that of Aya, who would far prefer to spend every minute outside, soaking up everything around her and avoiding the aggravatingly finite boundaries of a room or a house. As far as she is concerned, the world and the sky are infinite, because they never stop, going on in an unending loop to create the world that they know. Perhaps the surface area is something which is set, but the possibilities have potential as never ending as the distance between one and two. Perhaps the infinity isn't particularly large, but it is infinity all the same- one of infinite possible infinities, creating a cycle which ensures that everyone has boundless potential, even if they themselves never realize that. Everyone has a million possible days that never were, or almost were, and they all compile to great this great amount of potential energy, so overwhelming that it can burn brighter than any supernova burning up in space.
Aya has never been the sort to think of the vastness of the universe and feel small in comparison. Rather, she imagines its expansiveness and cannot but feel nearly giddy at the fact that, in all of that, she somehow managed to exist, thanks to a lucky formation of particles and timing. The universe does not dwarf a person, but accentuates every possibility that they represent. It is the manifestation, edgeless and impossibly improbable, of all that every person and creature holds within them. And Aya thinks that to be one of the most magnificent things to ever be.
The young girl notices Kaiko stretching, and follows suit without actually thinking about it. Energetic and athletic as she is, it comes naturally for her to stretch, especially when someone else is doing it as well. She is ever a social creature, after all. "Oh? Sure! You'll probably lap me a million times, but I'm up for a race!" the auburn-haired girl agrees cheerily. When it comes to swimming, she is quite excellent, and Aya has a knack for soccer as well. However, she isn't spectacular at running. Of course, the young woman is a good runner based on warming up for other sports, and soccer dictates that she can go rather quickly, but she isn't a racer, and short distances are not her forte, as her best qualities are her reflexes and endurance. More likely than not, Kaiko is her superior when it comes to running. Aya realizes this, but doesn't care, because she is feeling even more energetic than usual, and wants to try and put the energy to use.
"We should hurry, before the event is announced," Aya adds with a smile.
