Casshern Sins s01e22
Titre original : Drops That Are Named Eternity
Dio captures Casshern and brings him back to Luna's castle. Leda wants Dio to be healed along with her by Luna, but he refuses. Leda finds Luna and orders her to heal only those that are chosen, like her. Meanwhile, Braiking Boss is followed by robots on the verge of ruin. Leda receives Luna's healing, but it is not enough as she starts to break down again. She demands more healing from Luna, who complies. However, the increased healing she receives is much more painful than the first one. Dio takes Casshern away for him to regenerate so that he can battle him again in a fair fight. Casshern learns that Dio's reason to live is to defeat him. After a painful regeneration, Casshern prepares for one final battle with his arch-nemesis.
