"A ghost in the forest? And you went to see it alone?" Howl was not usually an overbearing kind of sister. If her brother wanted to explore on his own, he had the full freedom to do so as long as he promised to take care of himself.
And Shou was not weak. His innate magic was stronger than some of the fully-grown magicians Howl had the pleasure of meeting. It made Shou well-protected and also well-established in the social hierarchy. Some so many people had their eyes on Shou already.
But something about this situation bugged Howl. She was not sure what it was about, but there was an unsettling feeling inside her heart when she heard about the ghost of the forest. Maybe it was just because of all the talk about the 'killer' that was floating around the royal chambers.
