Cast: KUMANOMATA Kagiji

Fuwa Wataru is a high-school age boy who loves cute stuff like stuffed animals. He's at an arcade one day, trying to win a cute new stuffed bear, when bullies show up to torment him. In fleeing from them, he happens across a very special toy-catching game---one that has a naked man in it. The man calls himself "Mofu-tarou" (after the name of the stuffed bear) and insists that he is a stuffed animal. He does seem to have genuine stuffed animal ears and a tail, at least. He follows Wataru home, determined to be his new stuffed animal. Wataru's life gets even weirder as his Mumu-tan stuffed bear starts talking, and he has to figure out how to hide his new Mofu-tarou "stuffed animal." 

The Demon Lord Tasogare's castle is a dark and frightening place, filled to the brim with various monsters. Any soul unfortunate enough to be imprisoned here is sure to be terrified by the horrors within. However, the human princess Aurora Suya Rhys "Syalis" Kaymin is a different case. Rather indifferent to her situation, Syalis worries about one thing and one thing only—sleep. Ever since the demon lord kidnapped her from her kingdom, she has not had a single good night's rest.
To alleviate her dozen dozing issues, the princess makes do with what she can find in the castle. Whether it be the fur of fluffy demonic teddy bears or the silky, blanket-like bodies of ghost shrouds, everything is but a means to ensure a peaceful slumber. With so many potential materials to craft items that can help her sleep at her disposal, nothing will stop the sleepy princess—not even death.
