Kadokawa has released a new trailer for Shinmai Maou no Keiyakusha (The Testament of Sister New Devil), a work based on the light novel by author Tetsuto Uesu (Hagure Yūsha no Aestetica). The video features the opening theme song "Blade of Hope" performed by the group sweet ARMS. The premiere is scheduled for January 2015.
The story of Shinmai Maou no Keiyakusha revolves around high school student Basara Toujou, a boy who is disturbed by a sudden question from his father, "Hey, did you used to say you wanted a little sister?"
His father announces that he is going to remarry and will bring two beautiful half-sisters, but then embarks on a trip abroad. However, the two sisters, Mio and Maria Naruse, are actually two demons. Tetsuto began publishing the light novel with illustrations by Nekosuke Okuma (Nitroplus) in 2012.
A manga adaptation is set to be launched in Shounen Ace by Kashiwa Miyako.
