Legend says that whoever controls the Orochi will be granted limitless powers.

Suddenly, "Unknown" storms into the exhibit, shooting at everyone in sight and slashing Chizuru Kagura in the stomach with the Kusanagi Sword before running off with all three relics. He uses his blood and that of Chizuru to open a portal and disappear before he is captured. However, the sword does not vanish with him. It is revealed to Mai by Chizuru that the sword is a fake, and only Saisyu Kusanagi knows the whereabouts of the real sword.
