Saya and the others are to make their way to Darkness Embrace, the Black World. They have confirmed that the energy “Extra,” important to the worlds, is being lowered there. They are ordered to investigate, but someone’s there waiting for them…
Amane-san, I'm going to be your onee-san.
أماني-سان، سأكون أوني-سان خاصّتكِ
Amane-san,
Amane-san, yo seré tu hermana.
Amane-san, yo seré tu hermana.
Amane, je vais devenir
comme une grande sœur pour toi.
Amane, d'ora in poi ti farò da sorella maggiore.
Amane-san, eu serei a sua Onee-san.
