Nanatsu no Bitoku EP6 - No! That's Immoral!

Gabriel (Chastity) is lecturing a crowd against engaging in sexual activities when she spots her candidate. She immediately moves in with him and tries to clean up all of his immoralities - ranging from stealing his porn to dictating what foods, clothes he can have. On his day off, the candidate takes Gabriel to the amusement park, where she finally reveals her true angelic form and invites him to a "wholesome relationship" with her.
