Yuuki's trademark is being full of energy, but lately she's been late to the lessons, making mistakes, and overall not being like herself.
When Chisa, Airi, and Yuzuha ask Yuuki what the issue is, she replies that she's helping at her parents' restaurant because it's so busy.
But that can't quite explain the situation.
As Project Himmel's live show is coming up, the members bonding closer together is essential, so what is going on with Yuuki at this crucial time?
I don't know if it's an impostor, 
but Yuuki hasn't quite been herself lately.
.لا أعلم إن كانت محتالة لكن يوكي لا تتصرف على سجيتها
Jedenfalls verhält Yūki sich
in letzter Zeit sehr merkwürdig.
Eso da igual.
Eso da igual.
Pour moi, c’est bien elle.
A parte il discorso dell'impostora,
Não sei se é uma impostora, mas a Yuuki
não tem agido como ela mesma ultimamente.
Про самозванцев ничего не знаю,
но Юки и правда сама не своя.
