Trivia, insights & behind the scenes
This retells the entire 50-episode series as a standalone tragedy, not a summary — Kyoda wanted to explore what Renton and Eureka's love would look like under existential threat from frame one.
The title references the WWII-era song 'Goodnight, Sleep Tight' — a lullaby for children facing air raids, which explains everything about this film's emotional terrorism.
