Kinema Mosaic takes place one year after the original Hanayaka Nari, Waga Ichizoku. None of the six Miyanomori brothers made it to become the new head of the family, and so Genichirou is holding the competition again this year. In addition, he also takes the seventh brother to live with them in the mansion — Mamoru.
There are three modes in Kinema Mosaic: “second year mode", “epilogue mode” and “informant mode”.
