Testament of Sister New Devil

In this German manga-style comic series from Egmont Ehapa, Basara Toujou's ordinary life is upended when his new stepsisters reveal themselves as demonic beings bound by an ancient pact. Over nine issues published from 2015 to 2018, the series blends action, ecchi comedy, and fantasy as Basara navigates his role as a master—and protector—of the powerful Mio and Maria. While the original Japanese light novel and manga inspired the story, this adaptation stands as a compact, self-contained chapter in the franchise's international reach.
