The Nagahama Romance Robo Series (長浜ロマンロボシリーズ Nagahama Roman Robo Shirīzu) is a series of 4 Super Robot TV shows created by Saburo Yatsude and directed by Tadao Nagahama from late 1976 through early 1980 as co-production between Sunrise and Toei Animation, with Sunrise providing the animation work on their behalf.
The franchise was rebranded as the Robot Romance Trilogy by the Western fans, minusing Daltanious.
The series are notable for developing ideas from Brave Raideen, helping the mecha anime genre evolve from a subgenre 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.
