"Kroniichiwa! It's me, perfection. Also synonymous for Ouro Kronii!"
Time is an unwavering, precise entity, and its Warden - its overseer - is equally cool and impeccable.
Occasionally her exquisiteness leads her to decisions and bouts of luck that transcend the understanding of mere mortals. However, even utmost perfection finds no foothold in the face of her mortal enemy—disorder.
