The Sword of Seven Stars (Hànzì: 七星剣, Pinyin: Qīxīngjiàn, Onyomi: Shichiseiken) is a sword that belongs to Yuan's family. Ryo and Shenhua find it in the Stone Pit of Bailu Village. It appears to be made with a strange material and its grip is engraved with the constellation of the Big Dipper. In the Stone Pit, it seems to magically react to Shenhua's touch. After discovering it, she carries it with herself.
- Shenmue II designer, Norikazu Hirai declared in an interview that actually Yu Suzuki's original concept was a dagger. That's probably why in Shenmue III the sword looks a bit shorter than in the previous game.
- Many Chinese swords were marked with seven stars. According to Daoism, this was meant to protect the owner and ward off demons.
- In the Chinese classic novel Journey to the West, the two demon kings own a sword with this name.
