You don't remember the episode where Kagami gets miffed about Tsukasa forgetting to deliver the shopping list and Matsuri being an asshat about it, then trekking across the city looking for some ingredient while Tsukasa hunts her down so she can go all tsuntsun when they get back and Tsukasa mentions how hard Kagami worked for it?
Then again you may have just read the manga...which I know nothing about.
The Manga goes past the anime. Either way, the sisters will have to show up eventually. I find it hard to believe anyone could skip past all those parts.
