Kanuchi - Shiroki Tsubasa no Shou

In an ancient land once known as Naotsu, two rival families, the Takamahara and the Yasuna, were locked in constant conflict. A son from the Yasuna family, Izusami, and a daughter from the Takamahara family, Kayana, developed a forbidden romance. During the war's final confrontation, Kayana, with white wings, faced Izusami, who had black wings, resulting in his death and the end of the war. Kayana then assumed rule, but her once-white wings darkened to black. Two millennia later, in the region of Takamahara, where this legend is still remembered, a girl named Aki experiences a sudden and strange accident.
