What we're supposed to do is to fight, you know?

Yet, what is this farce you're saying that you're fine with doing only expeditions?

...Aren't you weird?

Kasumi-san, after saying those words,

resigned herself from the expedition squad.

...And then, after several times of combat she was not accustomed to,

she sank, according to the rumors.

Shiranui is afraid of sinking.
