Momoka Nishizawa

Like most of the other human characters, she isn't particularly changed too much... just somewhat exxagerated (to the point of stalking Fuyuki even in episodes where she doesn't appear). Compared to the other human characters though, she's the least changed out of all of them.

Relationships (Yes, we're skipping straight to this)
Fuyuki - She's probably the only one who actually likes Fuyuki... but it wouldn't hurt for her to back off a tad. If you can't already tell from that statement, she obsesses over him 24/7. Unlike the show, where Fuyuki is [seemingly] oblivious to all of this, Fuyuki is now completely aware of this and just views her as a creepy stalker.

Tamama - Tamama seems to live with Momoka, in her mansion, but this is only really touched upon in a single episode. In spite of this, they don't really interact with each other very often (due to Momoka infrequent appearances), but they're on good terms with one another (in Taruru's debut, at least).

Kululu - Due to her crush on Fuyuki, Kululu is insanely jealous of her and relentlessly insults her... whenever he happens to be around her, anyway (or if he's narrating, which only happens in earlier episodes, where he doesn't appear).
