Utsubogi-san put her two hands together.

And swiftly dove into the water.



It was at that moment.

The entirety of the water that filled up the pool, in an instant, really in the blink of an eye—froze over.

The whole surface.

Turned into ice.

“Eh… Eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeehhhhh!?”

I unconsciously let out a scream of confusion and shock—to think that the entire pool would freeze over as soon as Utsubogi-san dove in!

「It’s what they call, supercooling, you see.」

Kumagawa-kun slowly stood back up as he spoke.

It seemed that he’d shrewdly removed his hands from the pool at some point—and, with that, he took a step onto the pool.

He began to walk on the frozen ice.

Without sinking, and especially without drowning.

Supercooling… If I remembered correctly, if you put a bottle full of water in the freezer and cool it down calmly without any sort of shock to the system, then the water would remain in liquid form even past the freezing point. But when you introduced a shock to it, then the water would freeze up in an instant. Was that what he meant?

He’d performed supercooling.

On a pool of this scale?



「Basically—from the water of the pool, I made its 'temperature’ as if it never existed.」



Kumagawa-kun began to explain as he walked over the ice.

「By taking away only the 'temperature’ of the water, it basically became the ultimate way of cooling it down calmly, which just happened to accidentally supercool it, you see. So in order to freeze it over, I needed some way to shock the system.」

“You needed some way…”

Don’t tell me…

Utsubogi-san’s dive…?

So Kumagawa-kun had noticed her “tendency” of entering the pool by diving in, all the way back when he had been drowning… No way, he utilized Utsubogi-san’s beautiful, breathtaking dive for a purpose like that…?

Ah, but if I remembered correctly, when you wanted to take a bottle of water that underwent “supercooling” and freeze it in one go, you could drop a marble into the water—in that case, was the role of the marble taken up by Utsubogi-san…?

So saying that the sword was about halfway out was just an excuse to get her to dive in… Or rather, it was just a big fat lie!

How could this person do something like that to a girl!?

You can’t just pretend it was an accident!

「What are you saying? It’s the lifelong dream of any boy to be able to preserve a beautiful girl in ice.」

He wasn’t even showing any signs of guilt.

In fact, he almost seemed boastful.

「Water is quite a strange liquid, after all, since its volume increases when it freezes. But although it’s in a solid state, as you can see—even if it rises out of the water, it doesn’t spill over or overflow. So it wouldn’t fall under the definition of “draining”, right?」

Indeed… Even if it had turned into “ice”, the “water” was still “water” in the end—it was even more of a direct approach than hardening it with cement or mixing it into mud.

Without even needing to add anything.

Just by subtracting something—he achieved his goal.

It was very much a Minus worthy of Kumagawa-kun.
