Sachi is worried about Hiro, so she brings Erika along to follow her and learn about her.
Calling her my "sister" 
doesn't feel right lately.
.مناداتها بـ"أختي" لا يبدو صائبا مؤخرا
In letzter Zeit erkenne ich meine
Schwester nicht mehr wieder.
Últimamente no me sale natural
el llamarla "hermana".
Últimamente no me sale natural
el llamarla "hermana".
Je ne reconnais
plus vraiment ma sœur.
E ultimamente anche
definirla "mia sorella" mi fa strano.
Chamá-la de "irmã" não tem
parecido certo ultimamente.
Почему-то пропало чувство,
что она моя сестра.
