The Spirit Weaver is a visual novel game set in the beautiful and mystical realms of the spirits. A strange darkness known as The Entropy is threatening the realm, absorbing the spiritual powers of its denizens and causing many to disappear. You play as a Tarot Reader, summoned by your Spirit Guides to bring aid to the realm. Your mission is to meet and get to know the various confused spirits, help guide them by using the power of Tarot, and ultimately restore balance to the Spirit Realm.

This is a bittersweet story about love, grief, and finding ways to keep moving forward. To progress, you must listen to the characters' stories and empathize with how they think and feel to find the best solutions for their problems. The core gameplay revolves around performing Tarot readings. Much like real Tarot, there are no "wrong" or "right" interpretations of the cards, just better and best ones. The quality of your readings determines the fate of the Spirit Realm and your own story.
