English Translation

The manga is fun to read and had the fans laughing out loud, but there is still no confirmation on exactly when this will come out, but we are expecting it to be out in fall 2020. Viz Media had licensed the series in September 2017 for North America, and the first volume was released on June 12, 2018.

Viz Media officially describes the story as follows:

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.
