英文あらすじ（Synopsis）：

Chihaya's anxiety is growing again. Aya has been under for well over three minutes without air. Something may have gone terribly wrong - and it may be that only Chihaya can save Aya in time. She is scared, remembering the bitter pain of saltwater gushing down her nostrils and throat. But after a while, Chihaya manages to have her courage up. She dives in with a big splash, looking for her younger cousin and friend in distress.

　すると突然、何か速くて硬いものが、千早の身体にぶつかってきた。

　ぼやけた視界の中ではあったけれど、それは確かに、口元を手で押さえながら泳ぐ華奢なショートカットの少女だった。

All of a sudden, something hard and with tremendous velocity came out from the mess hall and struck Chihaya's body. The collision seemed to make it fall back, but only briefly. Its motion soon resumed, flipping and speeding down the corridor and toward the air-pocket Chihaya had come from.Chihaya's sight was too blurred to make it out, but she knew what it was. It was Aya.
