This one seems to be forcing a concept harder than mathematic cooking. Only this time it does not make much sense. During the teleportation girls' bags were not moving towards the ball or towards the... Wherever the ball was going. Then after the teleportation (which somehow separated Rina, but that's just a trope, I guess), there were several occasions when the girls moved some distance without carrying the bags, but they just magically appeared near them. The "fight" with the balls also defied physics, because the ball just jumped from the ground straight to the guys' faces.
They are trying too hard. Probably just like Rina, who felt extremely uptight, even though I do understand her frustration to some degree. I mean, one of the girls have not learnt to play in a year, apparently. Don't get it how that's possible. Blonde and four-eyes looked potentially interesting, but not enough to keep me watching.
