The Testament of Sister New Devil Departures

The Testament of Sister New Devil Departures is a special episode that follows the second season of the series. After resolving the conflict in the demon world, the cast finally gets the chance to take a vacation and enjoy some peace.

At the center of the story is Basara Toujou, a former member of the Hero Clan who ended up living with his two stepsisters: Mio Naruse, the daughter of the previous Demon Lord Wilbert, and Maria, a mischievous succubus. Bound to Mio by a master-servant contract, Basara has sworn to protect her from everyone who seeks her power, while his childhood friend Yuki Nonaka and the other girls around him have grown just as close.

With the dangerous battles behind them, Basara and the girls set off to relax and spend time together, and their getaway is filled with the series' trademark mix of comedy and steamy fan service as the bonds between the heroes grow even deeper.
