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?
She's always serious, always gives 
everything, and never gives up!
!إنها جادة دائما، تبذل كل ما في وسعها ولا تستسلم أبدا
Sie ist immer ernst bei der Sache,
gibt immer alles und gibt niemals auf!
Siempre se lo toma en serio,
lo da todo y nunca se rinde.
Siempre se lo toma en serio,
lo da todo y nunca se rinde.
Elle se donne toujours à fond
et n’abandonne jamais !
Fa sempre sul serio, dà tutto quello che ha
e non si arrende mai!
Ela é sempre séria com isso,
dá tudo de si e nunca desiste!
Она очень серьёзно к ней относится,
так много трудится и никогда не сдаётся!
