Katsuo brought the paper with him as he immediately leaved the room right after learning that one of the puzzle piece was hidden behind the school building. He rushed to the stairs. Skipping one every time he take a step. In less than a minute, Katsuo reached the back of the school. He was catching his breath as he search for the puzzle piece. He was under the shade of the building's shadow. The back of the school building was clean. But there, he found another piece of paper taped on the wall. He plucked it and read the paper's content.
"This is not a treasure hunt but you will find me deep within the dirt."
