The Ten of Swords represents disaster and martyrdom. One has reached the very bottom misfortune, with no direction to go but up.
This card shows Kotori bound by wires, about to be hoisted to the cross upon which she will be killed. In her prophetic dreams, she decides to "shatter" in place of the Earth, making her one of the many martyrs in the series. Even before, she could evoke pity in others because of her weak heart and because of the brave front she put up in spite of it. Her entire life seemed to be one long tragedy from her mother's death to hers. Yet afterwards, she revisits Kakyou and departs in peace, with a message of hope for those still living.
