One Hundred Years

Born in a world riddled with Demons and a thirst for revenge, Yozora Kougetsu takes it into her own hands to find the one behind her family's demise by joining the Holy Peacekeepers of Japan, an organization founded on the sole mission to exterminate Demons and their creator. Along the way, she finds out things about herself that are completely unexpected, meets people she never thought to befriend, hate, and much less fall in love with─a love that lasted a lifetime and came once every hundred years.
