Page 4:
She's got a number fetish. Okay.
Page 5:
Damn, calm down. They're just cards. What did the Jack do to you?
Page 6:
Rentarou investigation time. Does she have no empathy at all? Rude.
Page 7:
Okay, still rude.
Page 8:
Rentarou trying. Is she good at math?
Page 9:

Page 16:
She's diggin' it.
Page 17:

Page 19:
He's the 0. ( ͡° ͜ʖ ͡°) Know what other number we could make? ( ͡° ͜ʖ ͡°)
