Yasakani no Magatama (ヤサカニノ禍魂, Evil Soul of Yasakani) is a special unit of Hades: Izanami.
While inactive, Yasakani no Magatama floats behind Izanami in a circular shape, breaking only when Izanami uses the bits to attack and throw her opponent.
When the unit is activated, the ring disappears, and Magatama appear and form a triangle around Izanami. They are connected very weakly.
The Magatamas can also shoot energy attacks at Izanami’s opponent.
The type and origin of the weapon are unknown.
