Can... Can she not count?

I wouldn't go so far as calling her a Stepford Smiler. She's genuinely nice and happy, she's not even depressed she can't count, maybe just a little regret. But she's the kind who would button down and work hard to learn, not get depressed.

Kyouko is miserably bad at math.

In hindsight, the 3rd panel really gets to me.

if Cirno see this, she might (with smug face) said "Eye can count to 9"

Kogasa and Kyouko. It's time to see Keine-sensei
