What is this

Connect what a cat can sense with what people try to hide — every forgery trick is real art history.

A quiet antique mystery visual novel

Mina & Kuro — Case Zero: Prussian Blue

Yanaka, Tokyo. While its owner lies in hospital, seventeen-year-old Mina keeps his small antiques shop, Aigendō, alone — until the night the black cat, Kuro, speaks. Then an elderly woman arrives carrying an old painting of a black cat beneath the moon. What she wants is not a price, but the meaning of the words her late husband left her. The blue in that painting is beautiful. Perhaps too beautiful.

This blue shouldn't exist in 1760s Japan.

How you play

You examine each piece yourself. The facts you find — the paper, the seal, the colour of that blue — gather as cards in your casebook. When you're ready, choose two cards that cannot both be true, and press where they meet. Kuro senses what objects hold; Mina reads why people hide. You are the one who connects them.

When a case closes, the game shows only how you worked — Expert, Apprentice, or Novice. Not a badge. A mirror.

Hints come in three steps, all of them free. There are no ads — ever.
