What happens tomorrow?

What else? Makoto freaks out.

When our duo wakes up in the morning, they are greeted by the smell of Ultimate breakfast, a tangible benefit of having Chisa in the house.

"Let's go, Mako-kun." After they get dressed (obligatory flustered Makoto), they notice something that causes Kyoko a wry smile and Makoto to pull her aside.

"Um, Kyoko? Were Chisa's...chest bumps...always that big?" Chisa's T&A had indeed grown, being affected by Kyoko's rule the previous night.

"Hmmm. I suppose you could see it like that, but there are a lot of reasons why they'd appear that way."

"Do any of these reasons involve a magical notebook?" Makoto really didn't like the prospect of altering someone he looked up to, even if he did, on some level, approve it.

"My primary theory is that we're significantly younger than the last time we saw her. She's younger too, but she had still finished puberty and most of her growing, while we have a way to go. We are smaller, so everything, including her breasts, appears bigger."

"That can't work! I mean, look at them!" Makoto whispered as to not gain attention. 'substantial' was indeed subjective, and the rulebook had decided that, in Chisa's case, it meant six cup sizes. This gave the future teacher a whooping J-cup bust with a complementary thiccening of her rear.

"It's the best theory I can come up with right now. And besides, my chest looks normal, doesn't it?" She knew this would cause Makoto to relent for a while. Hopefully, by the time he notices the changes to the world, he'll used to the benefits of having so many busty women around.
