Intro
Jeez! Guest, you're so slow! We're gonna leave you behind!
A deep blue sky and white sandy beaches stretching forever. Under the mercilessly pouring sun, Minato was the first to raise her voice. She strikes a huffy, angry pose while her brown twin-tails sway, but her face is melting into a grin.
Honestly, Minato, you could at least help out a little.
Mio laughs as if exasperated, bouncing a beach ball in her hands. Her short black hair sways lightly in the sea breeze.
Come now, Guest. We'll help you, so let's catch up quickly. I get worried leaving Minato by herself.
Nagisa approaches while elegantly holding down the hem of her pareo. Wearing a mature smile, she peers up into my face.
Uuu, everyone, please don't leave me behind...!
From the very back, Shizuku walks up timidly and unsure of herself.
Shizuku, you can't be alone either. If you're by yourself in a place like this, guys will start swarming you.
Mio catches Shizuku firmly and brings her in front of Guest.
