Ginko (silver child) is the younger of the Echigoya sisters. She attends the same elementary school as Asu and is also a class representative, but considerably less popular, since her personality is more domineering than Asu's. Ginko has troubles understanding her older sister. She feels that she is a constant disappointment to her older sister and that Kinko must dislike her. Eventually the troubled Ginko manages to understand her sister a little better and patch their relationship somewhat thanks to advice from Asu and her covert observations of the Yamada sisters' homelife - through a telescope. At one time, the sisters kept a pet alligator named John in their garden, who had been visited with the indignity of a bow ribbon.
