An extremely powerful weapon born between the union of the Kusanagi-no-Tsurugi, Aeroga, and the five Lost Swords. In addition to it being a Lost Sword, it retains the Mythical godlike properties that are present in the Kusanagi-no-Tsurugi; i.e, Aeroga contains the souls of Kintaro ,Shiro's Father, and Googolplexio(The First Separation) and Kusanagi-no-Tsurugi contains the Soul of Yamata-no-Orochi

Due to this, it has the ability to produce a Soul Armor that is far more powerful than the Troy's Gaikishin's Soul Armor
