- This card is based on the Yata no Kagami, one of the three Imperial Regalia of Japan. The other two are "Sword of Kusanagi" and "Orb of Yasaka".
- This is the only Imperial Regalia card that does not appear in another card's artwork.
- This card's effect is likely based on the fact that in Japanese mythology, Amaterasu once sealed herself inside a cave, and once she was baited into looking out, she became entranced with her reflection in the Yata no Kagami.
- The Spanish lore of this card uses the word "regresar" instead of "devolver" for the term "return".
