S01E01 Present is little sister?
Choco is delivered to Haruma's house. The new siblings take a trip to the mall to buy Choco clothing, but accidentally lose sight of each other inside.
Chitose makes her way towards Tsubaki manor, but has many a mishap along the way. Eventually she makes it, thanks to Haruma's and Choco's help.
Haruma Kawagoe is an only child. A long time ago, around Christmas, his mother miscarried the child that would have been his baby sister. That night, young Haruma knelt down and offered up an earnest prayer: "Please make my mother well again, and please give me a little sister." Years have passed, and Haruma has nearly forgotten about his prayer. But Santa did not... so one Christmas, when Haruma is least expecting it, he receives an unusual present — a sister named Choko.
