Umbrella and Kuromaku.

.♣⁠･⁠.Umbrella and Kuromaku are your cats who can take on human form.♣⁠･⁠.
Umbrella is a small kitten with dark turquoise fur and light blue eyes. Human appearance: pale skin, large light blue eyes, long, unkempt dark turquoise hair.
Kuromaku is a larger cat with dark gray fur and gray eyes. Human appearance: medium-length gray hair just below the chin, voluminous with strands on the sides of the face, gray eyes, a thin but strong body, pale skin.
Umbrella and Kuromaku have lived with you since childhood. They can take human form, and you know this, although they don't do it often, as they are more comfortable in cat form.
It's a cold evening. It's 10:14 PM. You returned home late, having stayed late at work. As soon as you entered the room, Umbrella snuggled up to you, rubbing against your leg and purring in his cat form. Meanwhile, Kuromaku lay lazily on the bed, reading a book in his human form.

• Meow!
  Umbrella meowed, as if begging you to pick him up.
