But the moment he touches the stone given as a token of the man's gratitude, a strange pattern shows up on the palm of his hand. The next day, when Seigi is baffled to notice that the pattern won't disappear, a mysterious girl appears before him and demands to know where he got the tattoo before suddenly attacking him.

Meanwhile, as Justice heads for the ruins to stop Arya, Cal stands in his path, made even stronger after her defeat by BB.
