The next day Ryuusei, who had regained consciousness, told Chiro that yesterday he had found a mysterious book that had a black aura. 

"Hey, Chiro yesterday I found a mysterious book in the forest" For not believing Chiro to laugh at his brother.

"Huh, did you find a mysterious book in the forest? ... Did you joke yesterday when you fainted I didn't see any books around you ... Are you delirious, you better rest and calm your mind".
