It is very intuitive! Mostly! There are some button combinations.

He tries to memorize them and get a feel for how all the things combine!

After he beats his enemy Takuma instructs him to do a series of controller button presses in quick sequence.

Uhhh okay he can try that.

Takuma laughs as Anthony's character proceeds to very gruesomely tear their opponent in half, with gore and blood to spare.

Yay! (He thinks!)

Does it work if he does it again and can he just keep using it to win?

No it only works after he's defeated his opponent.

"I think you're ready to play for real."

"Mmmaybe?"

(Ugh, annoying.)

So they can play!

Anthony is not amazing! Hopefully Takuma is taking it easy on him.

Not too easy. But eventually he does leave the boys be.

Anthony tries to smile very nicely and politely and nonweirdly while Takuma leaves.

He looks over at Kaede.

The relief is not visible.

"Should we play another game?"

"Please," he says, removing that game from the console.

"Pick any or some specific –?"

"Anything but that."

He picks a platformer near him and puts it in the console.

"… Sorry."

"Whatever for?"

He gestures vaguely at where Takuma left. "… That."

"Been dealing with it all my life. He's being nicer now—I haven't been visibly a girl since I got back."

"Yeah." (Ugh.) "That'd – probably help."

Anthony looks a bit awkward.

"Does help, yes." He looks around, determines his sister is not relevantly spying, and leans forward to plant a kiss on Anthony's cheek.

Anthony smiles, trying to suppress the awkwardness.

"Anyway –" He gestures at the screen. "Let's?"

"Do let's!"

They are let.
