Eiro walked into the large open room that everyone here usually spent their time in when they wanted to be together. It was directly adjacent to one of the doors leading to the gardens, hence why the Demon chose this place to settle down for now.
He dropped onto one of the soft couches that was there and stretched out a bit. His whole body was completely sore after he used that new muscle-building method for only half an hour. Well, he managed to make improvements worth a couple weeks, so that was to be expected.
And of course, these 'improvements' didn't mean that Eiro built more muscle-mass, just that he he had developed certain strands of his musculature a bit more, and let others wither down just so slightly, so that he could move around better for his style.
