Haruka ：FREE! Drama CD. Iwatobi High School Swim Club’s Activity Log. Nagisa ：“Nagisa and Rei’s Invention Series.”

Rei ：Why. Why won’t my time shorten?! Makoto ：This again, Rei? As I said, while you’re improving your form, your time isn’t– Haruka ：Don’t be so consumed by your time. Let the water embrace you. There, you will find your answer. Nagisa ：Oooh, you sound so cool, Haru-chan! Haruka ：Don’t be so consumed by your time. Let the water embrace you. There, you will find your answer. Rei ：You don’t have to repeat yourself. I know time isn’t important to you, Haruka-senpai, but as a new member, it’s important to me. I have to catch up to the same level everyone else is before the tournament! Nagisa ：That’s it! I have an idea! Rei ：No thanks. We’ve never produced any good results with your ideas. Not after how you covered me with slime and made my legs silky smooth… [shivers] Nagisa ：No, it’s not like that this time! We just have to invent a new way of swimming! Rei ：A new way of swimming? Is it okay for us to just come up with one? Haruka ：I only swim freestyle. Nagisa ：Right, freestyle! Freestyle means swimming freely. Since the crawl is the fastest, there aren’t many swimmers who swim otherwise, but according to the rules, it’s okay for you to swim any way you want! So, we just have to invent a stroke that’s faster than the crawl! Rei ：That’s easy for you to say, but… Nagisa ：It’ll be fine. With the help of your muscled body and your perfect brain stuffed with all sorts of theories and calculations… <font color=>Rei ：Heh! You do have a point. The theories for Newtonian mechanics, Hamiltonian mechanics, Lagrangian mechanics, fluid mechanics, mechanism, quantum mechanics, human factors and ergonomics are all perfectly arranged in my head. Finding a new swimming stroke will be no trouble at all. <font color=>Nagisa ：[claps] As expected of Rei-chan! <font color=>Rei ：Very well, Nagisa-kun! Follow me! <font color=>Nagisa ：Yay! <font color=>Makoto ：[laughs] This seems a little interesting. <font color=>Haruka ：Rei. Find your own freestyle. [plunges into the water]

<font color=>Nagisa ：Then let’s get down to it! <font color=>Rei ：Where should we start first? I recommend developing a form that reduces the water’s viscosity to its utmost– <font color=>Nagisa ：I think we should start first with the drill. <font color=>Rei ：Drill? <font color=>Nagisa ：Yes! Plunge through the water while spinning around like a drill! <font color=>Rei ：I see! That does sound fast. <font color=>Nagisa ：Then try it out the way I tell you to. First, stretch out your arms all the way up over your head… and place your fingers together. <font color=>Rei ：Like this? <font color=>Nagisa ：Yeah, that’s it! Good, Rei-chan! That’s very good! <font color=>Rei ：To add more for effectiveness, I’ll imagine myself as a spiral and add in a 75 degree angle turn to the right! <font color=>Nagisa ：Wow! You look like a real drill! <font color=>Rei ：Call me the Human Drill! <font color=>Nagisa ：Let’s work on your legs next! Try it using the form for the flutter kick! <font color=>Rei ：Like this? <font color=>Nagisa ：Rei-chan, that’s perfect! <font color=>Rei ：Hahaha! You just leave it to me! <font color=>Nagisa ：Then, while keeping that perfect form, try twisting only your upper body around really hard to the right. <font color=>Rei ：[twists] [twists] [twists] [cracks his spine] [screams] There’s no way any human can do that! What do you mean, twisting only my upper body around?! <font color=>Nagisa ：Ehhh, I thought you would be able to pull it off. <font color=>Rei ：I can’t! <font color=>Nagisa ：But you said all that snooty stuff about Hamiltonian mechanics and Lagrangian mechanics and whatever. <font color=>Rei ：I am human! I can only move like a human! <font color=>Nagisa ：Aw, too bad. Then keep your arms that way and twist your legs around at superspeed to make them into the shape of a screw! <font color=>Rei ：I can’t do that either!!! <font color=>Nagisa ：Boooooo. Rei-chan, you’re so selfish saying you can’t do this, you can’t do that. <font color=>Rei ：I’m the selfish one? Give me actions that only humans can accomplish! <font color=>Nagisa ：Hmm… in that case, how about doing it like a flying fish? <font color=>Rei ：A flying fish? …It doesn’t sound all that beautiful. <font color=>Nagisa ：What are you talking about?! Flying fish are really beautiful! When they glitter silver as they sail over the water, they’re like a butterfly soaring through the ocean! It’s perfect for you, Rei-chan! <font color=>Rei ：[giggles] A butterfly soaring through the ocean, is it? That does sound perfect for me. <font color=>Nagisa ：That’s right! Also, the fastest speed at which flying fish travel over the sea surface is 70km/h! They’re really fast! <font color=>Rei ：Very well! I will show you that I am the Butterfly of Truth who soars over the ocean! <font color=>Nagisa ：Nothing less from you, Rei-chan! Then let’s start with the butterfly stroke first! <font color=>Rei ：Just leave it to me! [swims] <font color=>Nagisa ：Okay! Now spread out your wings and fly! <font color=>Rei ：[tries] I CAN’T DO THAT! Do you see wings on me anywhere?! <font color=>Nagisa ：I thought you’d be able to pull it off somehow… <font color=>Rei ：I can’t, I’m human! <font color=>Nagisa ：Then… here’s our last resort. Want to try altering yourself? <font color=>Rei ：A–Altering? <font color=>Nagisa ：Yep. We’ll alter your body so you can swim faster. You know, like how pianists cut the bottom parts of their fingers so they can stretch out their fingers wider? The swimmer has to reshape his body just like that to be able to swim faster. Like putting webbing on your feet, for instance. <font color=>Rei ：Are you being serious? Isn’t that non-ethical?! <font color=>Nagisa ：Everyone does it in competitive swimming. <font color=>Mikoshiba ：THAT’S RIGHT! <font color=>Rei ：That’s… Samezuka’s captain? <font color=>Mikoshiba ：Hey there!

<font color=>Mikoshiba ：At our Samezuka Academy swim club, undergoing surgery to put webbing between our fingers is a basic move for all new club entrants! Just look at my hands! <font color=>Rei ：It has webbing! <font color=>Mikoshiba ：That’s not all. Once I take my clothes off, you’ll see something even more amazing! <font color=>Rei ：You have a shell on your back?! <font color=>Mikoshiba ：I even have a plate on my head! <font color=>Rei ：Ehhhhhh?! <font color=>Nagisa ：See? So, Rei-chan… here. <font color=>Rei ：W–What do you mean “Rei-chan, here”?! I don’t want to do this… T–There’s webbing on my fingers, when did that happen?! I have a plate on my head! A shell on my back! And my entire body is green?! <font color=>Mikoshiba ：That’s it! Now try it out by going against me in a sumo match! Ready, and… begin! <font color=>Rei ：W–Wait, why are we fighting with sumo?! <font color=>Mikoshiba ：Isn’t it obvious?! With kappa, it’s gotta be sumo! And the one who wins sticks his hands into the loser’s anus — the loser’s anus — and takes the mythical ball that contains his soul! <font color=>Rei ：Mythical ball…? Wai– No– Stop! [Rei screams]

[Rei wakes up] <font color=>Amakata ：“In spring it is the dawn that is the most beautiful. As the light creeps over the hills, their outlines are dyed a faint red and wisps of purplish clouds trail over them.” <font color=>Rei ：[gasps] (It was all a dream…? This sucks… Or rather, why was I in hijinks again with Nagisa-kun even in my dreams?! I even named the dream “Nagisa and Rei’s Invention Series”!)

[School bell rings] <font color=>Nagisa ：Are you okay, Rei-chan? It was rare seeing you fall asleep in class. <font color=>Rei ：Indeed. I can’t believe myself. <font color=>Nagisa ：You must be really tired! I mean, you’ve been working so hard lately on shortening your time! That’s it! I have an idea! <font color=>Rei ：W–What?! <font color=>Nagisa ：We just have to invent a new way of swimming! Freestyle means swimming freely. Since the crawl is the fastest, there aren’t many swimmers who swim otherwise, but according to the rules, it’s okay for you to swim any way you want! So let’s try it! <font color=>Rei ：Wai– Wait! Stop! I don’t– [screams]
