(MC POV)
The next pair was Manami and Kiyomi, the both of them seem to have something to prove to each other or something with how intense their gaze were.
They had brought their fight to another part of the continent and had materialised their domains to their fullest potential, plunging that part of the land in both light and darkness at the same time.
On Manami's side, a blazing sun was floating behind her, burning everything around to cinders. Opposite her was Kiyomi who had a moon behind her instead, covering everything in a radius around her in darkness with only the moon and herself being visible.
The two of them had been launching fire and ice at each other for a while, the land beneath them freezing over and burning up constantly.
Guess the big sister still wins.
