Do you noticed the kanji on the head of the bald man? (抹茶)

It means "Matcha" (green tea).

Do you noticed the kanji on small guy's puppet?

It means "Curse". The puppet is Mr. Cursey, but presumably not of Kain because the colour (white).

And now to Gray. It can be he isn't evil (a spion), but Frosch is a hidden evil. I know, can be confusing, but this is a another reason for Gray to kill Frosch.
