9S is faring pretty okay. The first few arrows, he scores Good! and Great!, but as he figures out the timing of it, then it's basically maths to him. Though the music is audible, he isn't using the music to assist his steps, going purely off what he's seeing on the screen.

But... something he's noticed is that the animated character dancing in the background of the screen is using a different technique to Yuya. Where the character stands in the centre, Yuya is standing on the arrows. Why? He doesn't see why Yuya would use a different technique to what's being dictated on the screen...

When the song finishes, 9S has scored reasonably well; after the initial learning phase of Goods and Greats, the rest of his score is filled with Perfects. The song was easy, after all.

"Let's try something harder. That was too easy!"
