Yata Mirror

Yata Mirror (八咫鏡, やたのかがみ, Yata no Kagami) is a Spectral Armor Spell.

Description
The Yata Mirror is a shield which has the unique ability of reflect some elemental spells. According to legends, the mirror is compound by water, fire, earth, air and lightning, reason to it reflect this elements. The mystic defense of this shield can take powerful magical attacks without being even scratched but is completely useless against physical attacks. Non-elemental magics and other elements (ex.: iron, wood, ice) aren't reflected by the Yata Mirror, but are blocked by it.

According to Kazuki, the shield is powerful enough to block even extremely powerful magical attacks, as Urano Metria, although taking considerable damage. The few spells that can break the Yata's shield are immensely powerful, as Fairy Law and Grimoire Law, or Fairy Glitter (when full charged).
