Pretty sure she noticed Yukari showing up earlier.
I'd not be surprised if Yukari knows perfectly well who she really is and why she is really there as well.
So you called me......because you wish me to stop this......is that it?Uh-uh.We've only just met, Konngara......but it's because with the powers I have......I've got very few friends.And what of Youki-dono...Tell him..."I will protect Yuyuko-sama, no matter what I must sacrifice."I want you and Yukari to witness this....I'm sorry..... That's what he says, right?But I can never die.
