In the Heaven's Feel trilogy, Rho Aias is specifically identified as Archer's shield. After Shirō loses his left arm protecting Illya from the Shadow, the dying Archer transplants his arm to save him. Shirō later risks self-destruction by using Archer's arm, which grants him access to Archer's abilities, including Rho Aias. The shield is deployed during the climax of Spring Song when Shirō, having reaffirmed his desire to save Sakura, forms a temporary pact with Rider. Together, they combine Archer's Rho Aias with Rider's Bellerophon to defeat the corrupted Saber Alter.
