Er Gua is the second paper figure created by Chang Ming, accompanying Sha Dan on the same mission. He is more laid-back and philosophical, often lying on the ground and pondering questions. He assists in the search by directing the other constable. He shares a playful dynamic with Sha Dan. Both figures melt away at dawn after successfully leading the constables to the dismembered body. His contribution, though less direct, is still vital to the operation.
