Rodney: What do you know about the tower?

Shuji: Well, from my studies, there appears to be Guardian Shadows that follow Arcana numbers 1 to 12. If you hunt them down, then you should be able to remove the seals that now separate the blocks of Tartarus. I heard about rumors of people being kidnapped.

Rodney: They're true.

Shuji: Oh my, then they must be inside of the tower.

Rodney: How do we get the Guardian Shadows to appear?

Shuji: Well, you would have to wait for them to appear on nights of the ful moon. That's when the strongest Shadows appear.
