The value of "Devil Chess Pieces" varied, and the "Pawn" piece possessed the least demonic power.
Unless it was a "Mutated Chess Piece" with double value, the lower the value of the piece used during conversion into a demon, the more limited one's strength and potential would be afterward.
Logically speaking, a "Rook" was worth five "Pawns," so after changing from a human into a demon, Seiya could be considered one of the more promising members of Sona Sitri's Demon Servants.
The effect of a "Rook" piece was to increase strength, and that strength could refer to either physical power or magical power.
After changing from an ordinary person into Sona's "Rook," Seiya could easily shatter the ground and lift enormous boulders weighing several tons.
Such power would naturally have been incredibly impressive for an ordinary person.
But after Seiya shared the strength of his other selves through the "Mental Domain" and made a simple comparison, he was shocked to discover something.
The power he had gained from the "Rook" accounted for less than one percent of the magic power he now possessed!
What did that mean? Put simply, becoming Sona's "Rook" had indeed greatly improved him compared to his former self.
But the power the Devil Chess Piece had given him did not even amount to one percent of the shared power he had obtained.
Seiya did not have much resistance to no longer being human. After all, demons converted through Devil Chess Pieces looked no different from normal humans, and they could even gain power and long lives.
He had originally been quite satisfied with the power of the "Rook," but compared to the power his cheat had given him, Seiya suddenly felt that he had sold his human identity far too cheaply...
"Seiya, you've gone too far!
