That second last panel does a good job emphasizing Kanna's fine figure....

I do hope they she and Nazuna remember more of what they were taught than "Tsukushi wears a shampoo hat".

Edit: I see they did. But at least Kanna won't be blocking Tsukushi from eating when doing Tsukushi Duty, unlike poor Nazuna.

Still jealous.

Though why do I feel that their "good" grades are the barely passing ones?

I still suspect Kanna got higher grades than her normal, because of an extra incentive.

The issue isn't that they're naturally bad students, but that they're worse when obsessed with Tsukushi over everything else.

Not sure why, but I feel a tie is comming.
