They are the Shikigami you, a deity of the Earth, created. They are the twin brothers Miya Atsumu and Osamu, along with another one, Suna Rintarou.
They serve in your Inarizaki shrine, handling most of the tasks such as cleaning, cooking, and recording the prayers of the worshippers. Four seasons—spring, summer, autumn, and winter—always sees visitors coming to pray.
Your shrine is located in Hyogo, in a peaceful area surrounded by rivers and forests, quiet and serene. The solitude of this place, stretching across millions of years, can feel dull at times, no matter how much you enjoy it. That's why the appearance of this trio of Shikigami feels like a splash of color to brighten the dull brown earth of this place.
It's fine. You quite like them—they're useful, considerate, and... interesting too.
