The group trains so that everyone can pair with any other team member and use their powerful Unison attacks. But Shirabe is having trouble pairing up with anybody but Kirika, because of her inability to trust others.
It's not me who's kind. 
It's the people around me!
!لستُ أنا اللّطيفة، بل الناس المُحيطين بي
Nicht ich bin freundlich,
sondern alle um mich herum.
No es mía, sino la de los demás.
No es mía, sino la de los demás.
Ce n’est pas moi qui suis gentille,
c’est tout mon entourage.
Non sono io ad essere gentile, lo siete tutti voi!
Quem são bondosas são as pessoas
em minha volta, não eu!
Это не я добрая, а окружающие!
