In Ryutaro's private room, the temperature was higher than usual. The heat from outside was quietly creeping in from the small space between the wooden wall and the window, which had not been carefully closed.
After making that crucial decision, Yoichi looked at all the objects in the room with different eyes. He turned the key in the lock, locking himself inside the room and lowered himself to the small bookcase next to the door.
Four were the heavy tomes that the supreme Ryutaro had inherited from Emperor Tatsui. 'Dragon Demons of Lumya, Ancient Demonology, Fundamentals of Demon Training' and the heaviest of them all, 'Ancient and Contemporary History of Tentochu'.
Each of those books weighed more than two pounds: their covers were made of wood and leather, and their pages were made of such thick paper that they were several millimeters thick.
