Casshern Sins

The Paradise of Lost Hope (1x21)

:

Luna tells Casshern's group that her blood can grant eternal life, but her outlook on death has changed negatively, completely shunning it. She wants them to stay but Casshern and the others leave. Later Casshern changes his mind and wants to bring Ringo for Luna to heal, against Lyuze's protests. They reunite with Ohji, who tells them that Luna is not salvation; she grants death. A long time ago, humans found a way to live eternally, but Braiking Boss found it revolting and started exterminating humans, eventually giving the order to assassinate Luna. Ohji explains that the old Luna and the current Luna are different. However, upon witnessing Luna's results, Ohji forces Ringo to see Luna, but the girl refuses. Casshern reaches Dio and Leda's army who has come to get rid of Luna, but he allows himself to be brutally attacked by them.
