Shinmai Maō no Tesutamento (The Testament of Sister New Devil) Review!!


Hey J1 Fans, Devildriver1313 here. I’ve been checking out some new manga and anime and came across a story that I found kind of interesting. Shinmai Maō no Tesutamento or “The Testament of Sister New Devil”, is a light novel series written by Tetsuto Uesu and illustrated by Nekosuke Ōkuma. The story follows Basara Tojo who has recently acquired two new sisters, Mio Naruse and Maria Naruse, when his father remarries. However, Mio and Maria are not as they seem. Mio is a Demon Lord with incredible power who is being hunted by the current Demon Lord who is the successor of her late father. Maria is her succubus guardian. Together, they tricked Basara and his father Jin into becoming a family so they can have a place to live while in hiding. Basara reveals himself to be a “Hero”. At first he banishes Mio and Maria from his home until Jin tells him the whole story. From then, Basara decides to protect his devil sisters from the dark forces pursuing Mio.

At first glance, Testament of Sister New Devil closely resembles Ichiei Ishibumi’s series “High School DXD” mainly with the protagonists. Both Mio Naruse and Rias Gremory are red-haired Devil Lords, both Basara Tojo and Issei Hyodo are their male interests who possess great power. And they are constantly thrown into awkward perverse situations. What separates Testament of Sister New Devil from DXD is that Basara already has incredible fighting skill and unlike, Issei or any other similar male character in a harem type serial, he really is not vying for Mio though their master-slave pact does lead to some uncomfortable and interesting situations. But this isn’t just all sexual innuendos, the action that occurs when the main cast encounters the demons sent by the Devil Lord makes for good plot movement and the story behind Basara and his past serves as a great way to develop an understanding of this character, who he is and why he does what he does. Mio’s story is atypical with being a powerful heir, but her story is no less intriguing. Overall, Shinmai Maō no Tesutamento is still entertaining series with great action scenes and light comedy that shows the budding yet awkward relationship between the two main characters Basara and Mio. I recommend giving this series a shot. While it does bear semblance to High School DXD and the like, Shinmai Maō no Tesutamento presents itself in a way that is unique and fascinating.

Shinmai Maō no Tesutamento, “The Testament of Sister New Devil”, gets 3.75 out of 5.

The series is currently available for viewing on Crunchyroll!!
