Isuzu, This is a sortie, So don't forget it. Consider the formation of the fleet. Unexpected things might happen, so, To prepare for them, Expect the unexpected... I'm taking a lot of liberties here. Essentially, the joke here is that the initials of each sentence read out "It's very cute". The original sentence is more or less: "Isuzu, don't forget that we're in the middle of a sortie!! If we don't consider unexpected situations without compromising the fleet's formation, when that time comes, we'll be in trouble."

Look, Hatsuzuki!!

What do you think of my swimsuit?

Ufufu, thanks!
