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.
Shirabe-san is the only one unable to increase 
her phonic gain through teamwork.
شيرابي-سان هي الوحيدة العاجزة عن تعزيز
تضخيمها الصوتي من خلال التعاون الجماعي
Shirabe-san ist die Einzige, die ihr Phonic Gain
durch eine Zusammenarbeit nicht erhöhen konnte.
Shirabe es la única que no pudo
aumentar su phonic gain.
Shirabe es la única que no pudo
aumentar su phonic gain.
Seule Shirabe
Shirabe-san è l'unica che non è riuscita
ad alzare il suo phonic gain lavorando in squadra.
Apenas a Shirabe falhou em conseguir
ganho fônico com outras participantes.
Только Сирабэ не может увеличить
звуковую отдачу в командной работе.
