Three Imperial Regalia of Japan is the National Treasure of Kyoichi Kusanagi. So far, only two have been shown, the Kusanagi Sword and Yata's Mirror.

Appearance

Yata's Mirror

Yata's Mirror takes the form of a massive circular, translucent shield.

Kusanagi Sword

Takes the appearance of a long sword extended from within Kyoichi's hand with ribbons of blood surrounding it. When fully equipped, the sword changes form into seven branched-sword

Abilities

Yata's Mirror

Shielding: Yata's Mirror provides nearly absolute protection from direct attacks. However, with extremely powerful attacks such as Dante's Energy Wave, it can be broken.

Kusanagi Sword

It acts as a measure of control against Yamatano Orochi that has been sealed inside the firstborn son of Kusanagi clan. It is considered a god-slaying weapon.

Summoning: When slashing something, the sword can summon Yamatano Orochi out of the slash. This is the result of Kyoichi Kusanagi having Yamatano Orochi sealed inside his body.

Trivia

• Kusanagi's form as it's fully equipped might be inspired by Shichishitō (七支刀, Seven-Branched Sword), a sword of korean origin gifted to a ruler of japan in Yamato Period.
• When fully equipped, the webtoon refers to Kusanagi by its original name, Ame-no-Murakumo-no-Tsurugi (天叢雲剣, Heavenly Sword of Gathering Clouds).
• The final regalia of the three, unrevealed, is the jewel, Yasakani no Magatama which represents benevolence.
  • The sword represents valour and the mirror represents wisdom.
