To put it mildly, Jeri is a strange little girl who likes to pass
her time talking to her puppet. She became a Digimon Tamer when Leomon
appeared; however, Leomon's death at the hands of Beelzemon changed
her, and allowed the D-Reaper to get a foothold on Earth.
Still, there definitely seems to be some budding puppy love between her and Takato Matsuki (Well, there is...if you didn't see it I don't know what show you watched...)
