but where is something about its existence ? there wasnt single line like "hey btw there is no king piece" or oposite "hey you got high class promotion you get king pawn". i have done research and read again vol 1 - 5 for info. please dont take my uncertainty as ignoration of your responds and if you find some reliable info please just put it on wikia or in one of blogs (unless its something in new books)

"I become a 'King' in the future, for Buchou’s game I shall still be a 'Pawn'. "- pawn for old master game. :)
