The manga is an adaptation of the anime, so the anime is "borrowing" from the manga, it's the other way around. I'm not sure how much of the anime you've watched, but I can't think of anything that would leave you confused if you hadn't read the manga, so all I can say is that it would be explained in the end. It's not necessary to read the manga to understand the anime, and vice-verca.
Also, has anyone else listened to the K character songs? I find Kuroh's song hilarious.
"Kitchen's my space so nobody can invade!" XD
