Yes, well...However, with her burial to become a shikaisen, the whereabouts of the mokkan were lost.I do have these strips, but...When Her Highness was still young, the clan head Mononobe no Moriya suffered a grave defeat in a religious war and became a vengeful spirit, so she sealed him away with the power of the Four Heavenly Kings.They may have been once used by the Crown Prince.

She used a method of sealing the vengeful spirit inside a number of mokkan.But I believe it was a seal that got stronger the more the knowledge that "Moriya was sealed" was spread through documents or word of mouth.
*rustle*
I was not present at the time, so all I can do is speculate based on what you said, Keine-dono...
