About The Testament of Sister New Devil

When Basara Toujou's life is turned upside down by his father's sudden introduction of two new stepsisters, he's shocked to discover that Mio and Maria Naruse are not only beautiful, but also demons - Mio being the daughter of a former Demon Lord and Maria her loyal succubus servant. As Basara's instincts scream for him to flee, he's unexpectedly drawn to his new sisters and decides to use his own powers to protect them, forming a master-servant contract with Mio to watch over her.

As Basara navigates this treacherous new world, he's constantly under scrutiny by the Heroes, a clan sworn to destroy demons, and faces threats from hostile forces seeking to harm his new family. But Basara's own demons, both literal and figurative, threaten to consume him. Haunted by a dark secret from his past, he must confront his inner turmoil to have any hope of safeguarding Mio and Maria.

With the stakes higher than ever, Basara must balance his desire to protect his sisters with the danger that lurks around every corner. Can he overcome his own personal demons and emerge victorious, or will his new family be torn apart by the forces of darkness?
