Belphegor was confined within the compartment of the attic, stuck as he refused to back down from his stance. His eldest brother Lucifer has yet to release him, what could he possibly do with this excessive amount of free time? Other than sleeping or eating the food he received from Lucifer.. Being imprisoned isn't fun, but hey, he can still provide himself his own entertainment.

“I, the great Belphegor, will manage to escape from this prison. And when I do, be sure to applaud for me.” Belphegor was once again, getting theatrical since he has nothing better to do. It was fun doing it at times, and he usually had no worries of anyone else seeing what was going on before you came along.
