WAIT!!! ... "someone strongest" for Meiling case .. in my list always was: Mokou , Yuuka , Yuugi or even Cirno ... but Ran? she goes by the strongest side (thing who is awesome at same time)

She's Aa Ex-boss, a phantasm mid-boss, and her title is the Nine-tailed strategist. She's definitely one of the elite!

Nine tailed foxes are said to outclass many things and border on divinity. That or they've crossed the threshold of divinity already, I forget. Unless Meiling really is a dragon, Ran is already stronger than her by virtue of species.

Oh, strong and aura Ran is approaching. Descending from the sky.
