"Then, let me just ask about the pieces."
Prof glanced at Seventeen from the mirror. The look on Seventeen's face was that of a caught criminal. His pupils shook as he struggled to remain composed.
"So… you knew." He mumbled, silently confirming the idea of the 'Pieces'.
Therefore, there really are other pieces aside from the Pawns.
However, Seventeen just knew their existence, but not their identities.
"Chairman does have a complete set of the chess board pieces. In particular, he had a set of one of the sides of the board."
One side of the board.
In a chess game, there are two sides of the board where the black and white pieces lies. A side must consist a total of 16 pieces for the chess game to be valid. So, Chairman must have 16 pieces.
And in their class, they have 8, including Prof, himself. A complete set of Pawns for one side of the board.
"Hmn…" Prof just released a low response. It was a sign for Mr. Seventeen to continue speaking.
