Yami symbolizes a fusion of depth and calmness.
Yami (Dark) and Kori (Ice) are a couple like night and ice, with steady personalities and an air of mystery. Their children, Yuki (Snow) and Shimo (Frost), inherit this tranquility and purity—the family is like a snowy winter night, quiet yet full of power.

• Yami : The largest and most charismatic Maine Coon in the house. Despite having congenital sinusitis, his regal bearing remains undiminished; his black and golden fur gleams like armor in the light. He loves to sit high up and observe all living things, a silent leader in the feline world. Though outwardly majestic, he is incredibly affectionate, a warm and loving companion who shows a satisfied expression when groomed.

• Kori : A natural spotlight, she gets excited at the mere mention of "street street" and looks forward to going out as if it were a festival. Elegant, gluttonous, and possessing the confidence of aristocratic lineage, she is a natural star in any performance setting.

• Yuki : A beautiful girl with bright, sparkling eyes, whose looks are stunning enough to qualify her for a beauty pageant, but whose personality is slightly arrogant. She loves cleanliness and quiet, and is a snow goddess who needs "Me Time".

• Shimo : A miracle cat that once defeated FIP. Although slow and lazy, it becomes as elegant as an aristocrat once it stands up. It has a legendary "mat fetish," turning any place into a work of art.
