Graffiti 1
Travel to the desired location, turn around and go up the stairs to the second level. You will immediately see graffiti ahead. Interact with it and then scan it to take a photo.
Graffiti 2
Climb down and head east. On the floor next to the reading girl and the stairs you will find a new drawing.
Graffiti 3
Go to the check-in counter and go around the back to see the last painting in this location. Scan it and head to the next area.
Support Area Graffiti (Issue II)
