Father relocates his family, including daughter Himeno, to a large, old countryside mansion. This move initiates the story, causing Himeno initial distress at leaving her city life and friends. Discovering three small ninja spirits—Akamaki, Aomaki, and Kiiromaki—inhabiting the house, Father greets them with enthusiasm and practicality. He actively welcomes their presence, valuing their elemental abilities for assistance with household chores and repairs. When a large tornado threatens the mansion, Father joins the family and the ninjas in protective efforts, demonstrating his supportive, involved role focused on safeguarding their shared environment. His documented presence in the primary narrative remains confined to these events across any official sequels, spin-offs, or related media.
