Kira Finster is Kimi's beautiful biological mother. At first, she was single. Then, she became Chaz's second wife, and most importantly, Chuckie's new mother. In the series' big film, she worked as Coco LaBouche's secretary at Euro Reptar Land but apparently became unemployed after marrying Chas, and moving to America. Her first American job as revealed in The Fun Way Day was as co-owner of "The Java Lava Coffee House", with Chas co-owning as well. She is a very motherly woman which Chas quickly noticed.

Like Chas and Didi, Kira is an active reader of Lipchitz. In fact, she tried using a Lipchitz book, "A Step Up to Step Parenting" in order to help her bond with Chuckie better. Her Japanses heritage plays a big part in her life as evidenced by her use of Japanese words and honorifics when addressing Chas and sometimes with Kimi. Both her parents are Japanese and their favorite holiday is Children's Day, because they all go see their grandchildren on that day.

Chuckie came to love Kira very quickly and refers to her as, "Mommy".
