She and the girls go to swim in the beach, unaware of what's to come.

"Oh hi Chie!, Rise!, i see that you got changed fast!", commented Yukiko as she arrived to her friends on the beach.

"More like, you took more time than usual to change", Joked Chie.

"Oh sorry, it's just that the booth was full of sand, and for some reason there was loud sound coming outside of the booths", Yukiko explained.

"Yeah, i know what you're talking about, i heard that sound too", Exclamed Rise.

"You too Rise ?, in that case, what it could be ?", asked Yukiko Suprise.

"I don't know, but whatever, let's go swimming, for that's why we came here on the first place", Exclamed Chie with an smile.

"Yeah, you're right, let's go swimming!!", replied Yukiko happily, upon which, she and the girls went inside the beach's waves to swim.

_"Wow!, it has been ages since i last swum on the beach", said Yukiko to her friends as she ventured further into the ocean.

"I'm happy that you're enjoying this, but you should be more careful", said Chie concerned.

"Careful ?, of what ?", exclamed Yukiko confused, unaware of the impending threat against her.
