"Choose ～A Song of Joy～"

 is the eleventh episode of the Kämpfer anime.

Shizuku invites Natsuru over to her house to tell her about Kaede, getting her Burnt Alive Lion to spill the truth. She recalls that her friend Tamiko was killed due to the Kämpfer battle and has since sworn vengeance against whoever responsible for the establishment of Kämpfer combat. When Natsuru confronts Kaede about this, he once again falls under Kaede's hypnotism. With Natsuru under her control, Kaede and the White Kämpfers trap and capture Shizuku, Akane and Mikoto. Kaede tries to get Natsuru to finish them herself, but he spots a keychain he previously bought for Shizuku and snaps out of it, declaring that he will not betray his friends despite his love for Kaede. This declaration encourages Shizuku, Akane, and Mikoto to fight with renewed resolve, letting them easily defeat the White Kämpfers. Kaede tries enticing Natsuru once again, but he transforms back into Normal form, forcing her and the White Kämpfers into retreat. With the battle over, Shizuku, Akane and Mikoto turn their attention to Natsuru.
