This piece is the only one that's so distorted.

That's because it's from long before June 1983.

Therefore, the existence of this piece has no effect whatsoever in the game we're playing on this board.

But is this really a useless piece?

The identity of Rule Y has been completely exposed by now.

With the backing of a mighty organization, it is powerful enough to swallow up the small solidarity of individuals.

I almost gave up on this game because of its irrational power.

That's why I'm thinking...

that maybe there's a piece hidden somewhere that's strong enough to fight against such a formidable enemy.

Mamoru Akasaka works at the police headquarters in Tokyo, and might have the power to stand up to such a vast conspiracy.

Can his power withstand even Rule Y?

Just like Keiichi Maebara defeated Rule Z, will he be able to defeat Rule Y so easily?

...We need everyone's strength.

So Akasaka's strength is needed as well...
