Akane and Azami Kiryu are hostile female spirits in Fatal Frame II: Crimson Butterfly. They were twin sisters residing in All God's Village and previous victims of the Crimson Sacrifice Ritual. As Twin Shrine Maidens, their duty was to perform the ritual and ensure the village's survival. Although they succeeded in this, their love for one another ran deep and Akane, the surviving twin, suffered from serious trauma. Both of their spirits remained following the Repentance, trapped within the lost village.
