Hey, listen!

I just realized something amazing!

Something amazing?

For example, say there's two nights left until New Year's. That means we have to sleep twice.

But if you don't sleep one night, then that means there's only one night left. Do it twice and it means New Year's is right now! How cool is that?!

Which means pulling two all-nighters. That sounds pretty taxing...

More importantly, saying a day goes away if you don't sleep is just nonsense.

Heehee. It's called “logical thinking”.

Alright, fine. Let's put your theory to the test.

Test?

We'll do an experiment to test if what you're saying is right, Rin. You won't sleep for the next two days in order to see if it feels like one day to you.

Actually, we may not be able to call it a proper experiment since it's going to come down to her perception...

Wait, that means I get to stay up late!

Alright, you're on! Test me all you like♪

She might actually succeed based on her current energy level.
