[1] Suzuna's nickname for Yuuki is ヒデサイ (hidesai), which comes from her first character episode. It's a misreading of 秀才 (shuusai), which means "prodigy."
[2] Suzuna addresses Io as ちゃんイオ (chan-io), which is just an inversion of "Io-chan." I translate it as "Io-io" to convey the peculiarity and familiarity of the address.
At the Lucent Academy, summer vacation was only a couple weeks away. The classroom was abuzz with the atmosphere of the semester's end, as all the pupils shared their summer plans with each other.
Misaki
Everyone's getting ahead of themselves with all this talk of summer. Honestly, they're all like little kids... It's still half a month away, after all.
Suzuna
Hey, hey, Misaki, do you have any summer plans?
Misaki
Me? Um, well...
Suzuna
Sounds like you don't! Then, you're coming with me!
Misaki
H-Huh!? Don't just decide that on your own!
Misaki
What are you talking about, anyway?
Suzuna
Oh, yeah. Well...
Suzuna
I'm gonna be a model for an event! It's a seaside event, on an island that's super far from Landsol!
Misaki
Wow! That's amazing!
Suzuna
Ehehe, thanks!
Suzuna
After the end of my job there, I'll have some time off, so I thought I'd stick around and enjoy the island for a while!
Suzuna
And I figured I could invite some of my friends to go have fun together. I heard that the beach there is really pretty!
Misaki
Huh!? Then, you're basically going on vacation there!
Suzuna
Yeah, so I thought I'd ask you, Misaki. But it sounds like you're actually kind of busy, so...?
Misaki
Huh!? Umm... W-Well, let me check my calendar.
Misaki
Hmm, I wonder...
Misaki
... Ah, looks like I've got a gap right around then! And only around then, you hear? So, I'll just have to take the occasion to go with you!
Suzuna
For real? Nice, I'm super happy!
Suzuna
I don't know when's the next time I'll have such a huge gig, so I really wanted you to get to see me up close, too! And isn't it awesome to get to vacation with your friends?
Suzuna
Ah, it's you, Smarty![1] Yo! You're just in time! You're coming too, right?
Yuuki
1. "To where?"
2. "Of course!"
Option 1.
Suzuna
Whoa! Haven't you heard? We're going on vacation to an island!
Suzuna
You seem like you'll be free, so you could come, too!
Option 2.
Suzuna
Huh? Wait, did I already tell you about this?
Suzuna
Well, it's no surprise that you already know everything about everything, Smarty!
End of branches.
Suzuna
I feel like this summer is gonna be exciting!
Io
My, are you all going on a trip for summer vacation?
Misaki
Suzuna said she's going to an island for an event! We're going with her to cheer her on, and after that, we'll all go on vacation together.
Io
My, how wonderful. Congratulations! You're very impressive, Suzuna.
Io
How nice... I wonder if I could come along...? But maybe it would be awkward if your teacher went with you.
Suzuna
No way! I'd love to have you there too, Io-io![2]
Misaki
I think so, too! The more the merrier, right? Oh, but you're not allowed to tell us to study in the middle of vacation, okay?
Io
Ha ha, I'll be sure to watch myself. I'm very much looking forward to this.
Suzuna
I was a little nervous at first, but with everyone there, I think this'll be the most fun job ever!
So that they could enjoy their summer vacation to the fullest, Suzuna and her friends endured the rest of their classes.
