Aa! Megami-sama! Tatakau Tsubasa

Synopsis

A dark force causes several angels to collapse. Lind attacks it, resulting in an explosion. On Earth, Belldandy, Peorth, and Urd have a tea party with their angels. Lind, the legendary Valkyrie, arrives and declares a state of emergency. The Angel Eater has escaped, forcing Lind to investigate the temple thoroughly. Urd and Peorth are both attacked and incapacitated when they lose their angels. Lind, reminiscing about her past failures and her warlike nature, is comforted by Belldandy. Belldandy agrees to act as a lure for the Angel Eater while Lind stands guard, but once Lind loses consciousness and Belldandy is attacked, Lind realizes that the Angel Eater is within herself. Hild appears and reveals her plan to force devils into goddesses by consuming their angels and replacing them, turning them into demonesses.
