The Robot Romance Trilogy (長浜ロマンロボシリーズ, Nagahama Roman Robo Shirīzu, lit. Nagahama's Romance Robo Series) were three Super Robot anime series created by "Saburo Yatsude" (a collective name for the staff at Toei) and directed by Tadao Nagahama from late 1976 through early 1979. The trilogy, consisting of Chōdenji Robo Combattler V, Chōdenji Machine Voltes V, and Tōshō Daimos, was a co-production between Sunrise and Toei Company with Sunrise providing the animation work on their behalf. The series are notable for developing ideas from Brave Raideen, helping the super robot genre evolve from a series meant mainly to sell toys with little to no plot or character development from episode to episode, into a series capable of telling dramatic stories of human conflict and compassion.
