Rin let out a small sigh while the calling card pointed out the jeweled branch from the tale of the bamboo princess it was nothing special in the long run rather the calling card was to get people to focus their attention at a lesser things than her true goal which already had a calling sent to it. This was one of the few times she went after multiple treasures but the one she was after was to much of a target so getting attention away from her true objective was best so the jeweled branch of Kaguya was the best option it had little to it beyond being part of a strong legend. In front of her was a large mansion a bit old and decrepit but despite the age you can see its former grandiose state was still obvious behind the ivy and the rubble. While no one lived her for awhile it carried a item she sought but the mansion was often patrolled by cops and the so she sent a calling card to draw away attention away from it. She was still wary however she felt a presence nearby probably due to the close proximity to the museum where the jeweled branch was located. So it definately supernatural in origin.
