|Images of Three Keys|
With the existence of three keys further shadowing the true identity of the promise girl — in the midst of the confusion — Marika invites Raku to her home to pay respects to her father. Upon visiting Marika's father, Raku fears him and learns how much her father wants to throw Raku's father in jail. Raku also learns Marika's flustered side to her when Raku compliments her.

On both that and another console, the word "Shaft" is written, which is a reference to the shows studio.
