Hiro Shimono & Rikiya Noyama Join TV Anime Sleepy Princess as Brave & Monster

The official website for the forthcoming TV anime adaptation of Kagiji Kumanomata's fantasy comedy manga Maoujou de Oyasumi / Sleepy Princess in the Demon Castle has announced its two additional voice cast members.

Hiro Shimono (Connie Springer in Attack on Titan) is cast as Brave Akatsuki, who is a brave man who stood up to save the kidnapped Princess Syalis. He is a hot-blooded and straightforward, a true brave man-type person. However, the princess calls him "A-Nanaka-kun" and is not able to remember his name and existence for a long time.

Rikiya Koyama (Klaus Von Reinhertz in Blood Blockade Battlefront) plays Haritoge Majiro, a monster of a demon beast tribe. He works at the Demon King Castle as a lower-class soldier. He is two-meters tall and looks like a violence-loving person, but he has many friends because he can't say no to people who ask him to and good at reacting to people's jokes.

Synopsis (via: the manga's English edition publisher VIZ Media):

She decides to while away the hours by sleeping, but getting a good night’s rest turns out to be a lot of work! She begins by fashioning a DIY pillow out of the fur of her Teddy Demon guards and an “air mattress” from the magical Shield of the Wind. The princess’s hapless demonic guards soon discover that their captive expects to be treated like, well, a princess. Things go from bad to worse—for her captors—when some of Princess Syalis’s schemes end in her untimely—if temporary—demise and she chooses the Forbidden Grimoire for her bedtime reading…
