Translation
Nagisa ：“Swimsuit Invention.”

Rei ：[depressed] Why won’t my time go down… Makoto ：[walks up] Rei! What’s wrong? Rei ：Makoto-senpai. I was wondering what to do about shortening my time… Makoto ：Oh. Like I tried to say before, while you’re improving your form, your time is– Nagisa ：I know! It’s your swimsuit! Rei ：…Where did you come from, Nagisa-kun… Nagisa ：Don’t look at me as if I’m a maggot, that’s so rude. The cause of all your problems has to be because of your swimsuit! Rei ：Swimsuit? Nagisa ：Yeah. I saw on TV the other day that they invented a swimsuit with fish slime on its surface. Rei ：…Already, I’m getting a bad feeling about this… Nagisa ：That’s the sort of swimsuit you need, Rei-chan! Rei ：So, wait, let me recap. You’re saying it’s a swimsuit with gel on it that replicates the outer mucus layer of a fish, right? That’s not the kind of swimsuit a high school student is able to afford. Don’t be foolish. Nagisa ：The surface just has to be slimy, right? So… here. [takes out a bottle and squeezes onto his palm] Slime! Rei ：N-Nagisa-kun… where did you take that out from? Nagisa ：Never mind the minor details! <font color=>Rei ：It isn’t a “minor” detail! What do you intend to do with that hand? <font color=>Nagisa ：[grins] Come here, Rei-chan! I’ll make you slimy! <font color=>Rei ：[runs away] No! Get away from me! <font color=>Nagisa ：[chases] Rei-chan, wait! I swear this will help you reach your best time! <font color=>Rei ：Why is it that everything you come up with is insane?! <font color=>Nagisa ：I bet it was thanks to crazy ideas like this that Edison and Watson got their inventions! <font color=>Rei ：Watson is a molecular biologist! He’s not an inventor! <font color=>Makoto ：H-Hey! Nagisa and Rei, stop it, the both of you! <font color=>Rei ：You have to stop Nagisa-kun, Makoto-senpai! <font color=>Makoto ：Nagisa, stop it! <font color=>Nagisa ：Then I’ll make you slimy, Mako-chan. <font color=>Makoto ：Huh?! [backs away] Eh– wa– Nagisa– Wait!! <font color=>Nagisa ：[pours slime] Slimy slimy! [Makoto screams]

<font color=>Rei ：[claps his hands together in prayer] Makoto-senpai… I will never forget you! <font color=>Makoto ：I’m not dead! [Nagisa claps a hand on Rei's shoulder] <font color=>Rei ：! <font color=>Nagisa ：Heh heh heh. Rei-chan. I’ve caught you. ♥ <font color=>Rei ：N-Nagisa-kun… <font color=>Nagisa ：Here you go! Slimy slimy! [Rei screams]

<font color=>Nagisa ：All done! Now you’re definitely going to reach your shortest time yet, you two! <font color=>Makoto ：[slipping] I-It’s slippery…! <font color=>Rei ：Look ou– This is pretty dangerous– [Makoto and Rei struggle to keep standing] <font color=>Nagisa ：[giggles] You two look like baby fawns who are learning to walk for the first time. <font color=>Makoto /<font color=>Rei ：And whose fault is that?! <font color=>Nagisa ：Calm down. <font color=>Rei ：Nagisa-kun…! This really will… help to shorten my time… right?! <font color=>Nagisa ：You won’t know until you try! Try swimming, Rei-chan! <font color=>Rei ：But… this is… too slippery… I can’t… reach the diving board…! <font color=>Haruka ：[walks up] Hey, you guys. <font color=>Makoto ：[wails] Haru! <font color=>Nagisa ：Haru-chan! I invented a new swimsuit! <font color=>Haruka ：A new swimsuit? [pause] Rei… do you intend to go into the pool like that? <font color=>Rei ：Eh? U-Um… yes… Nagisa-kun said that with this swimsuit, I’ll reach my best time… So I’m about to give it a try… <font color=>Haruka ：Don’t. You’ll ruin the pool. <font color=>Makoto ：[whispers] Haruka is really angry! What are you going to do about this, Nagisa?! <font color=>Rei ：[whispers] It’s your fault he’s mad at me, Nagisa-kun! <font color=>Nagisa ：Eh?! You’re mean, you two! It’s not all my fault! <font color=>Rei ：It’s UNMISTAKABLY all your fault! I told you I didn’t want to– [slips] I’m falling! [Rei grabs onto Nagisa] <font color=>Nagisa ：Wai– Rei-chan! Don’t grab onto me when you’re all slimy like that! <font color=>Makoto ：[yells] Nagisa! Don’t push me! I-I’m slipping…! <font color=>Nagisa ：B-But Rei-chan grabbed me…! [slips] <font color=>Rei ：It’s not like I can help it…! <font color=>Nagisa ：Rei-chan…! Let go…! Of me…! <font color=>Makoto ：I said, don’t push me Nagisa! <font color=>Nagisa ：But Rei-chan won’t let go of me! <font color=>Rei ：I’m trying my best here too, you know…! …Wai– Nagisa-kun! Don’t move! Look out! [All three go sliding into the pool] <font color=>Haruka ：[sighs] They’re all idiots.
