The destination: W Island!
I am the Abyssal Admiral! Battleship Hime! AKA - Teetoku!
Ep 3 - Operation W-Island Picnic!
Yeah, but you didn't have to head straight off tomorrow...
Teetoku-chan... she wanted to come along with us!
The sea is apparently beautiful!

And hence, prepare yourselves with resolute hearts!
Snacks are to be limited to 300 yen!
It is sudden, but you all shall be taken for a picnic on the morrow!
And yet! A picnic it may be, but if you let your guard down, you shall be the ones being rescued! She actually makes a double-error: The standard phrase is "足を掬う" (to trip up/pull the feet out from under). Not only does she use an incorrect varient with "足下" (at one's feet/underfoot), she uses "救われる" (to be rescued) instead of "掬われる" (to be scooped up). From Pixiv comments, at least one of these may be author error.
It is simply not proper for solely Fubukin's lot to go on a picnic.
