The Testament of Sister New Devil

In 2016, Seven Seas Entertainment brought Tetsuto Uesu's light novel series to comics, with Miyako Kashiwa's art and a script team including Wesley Bridges and Steven Golebiewski. Over nine issues, this action-fantasy manga follows a high schooler whose new family life is upended by demonic sisters and a pact that awakens hidden powers. It's a compact, complete adaptation of the fan-favorite story, delivering supernatural battles and ecchi humor in a brisk, standalone run.
