Seiko Hata

Rika and Kristy's maternal grandmother, Seiko Hata, is quite open and acts as a balancing force between her daughter and granddaughter, with mixed results. From the beginning of the show, Rika's grandmother tries to connect with her, but Rika refuses to let her.

Later, Rika's grandmother discovers Renamon's existence and calls her Rika's "guardian angel." She doesn't seem at all surprised that Rika is a tamer and promises to keep her departure for the Digital World a secret from Rika's mother. Rika is surprised that her grandmother is so understanding and, from that moment on, becomes kinder and more open about her feelings toward her.
