"If I could use magic, what would I wish for?"

A title blending TRPG-style adventure, deck-building card mechanics, and puzzle gameplay.

Two narrative threads intertwine: a coming-of-age story centered on a card game rumored to grant the wishes of anyone who reaches the top rank, and a bizarre mystery involving a series of suspicious deaths in Kyoto. Decipher the works of Robert W. Chambers and step into the Cthulhu Mythos abyss lurking behind these events.

The King in Yellow, Hastur, The Yellow Sign... and the prophecies inscribed in The Prophets' Paradise will guide the characters.

These two threads eventually converge; as the true intentions of each character come to light, the story races toward its conclusion. Transcend countless time loops to uncover the truth behind the mystery.
