Khane

Khane (카네, Kane) is the younger sister of Dowon, a war hero who sealed herself within the Wall of Peaceful Coexistence. She is a Ranker. She's the only one who remembers her sister and her sacrifice as the other people of her town had their memories of her erased. She is also the only one that knows how to unseal Dowon.

History
Following the war history of FUG against the Zahard Empire, Khane and Dowon was still a child when Zahard declared himself as the King of the Tower. Their father is a Ranker and warrior of Dohwa. Their family could control Flower Shinsu for generations. One day, their father was ordered by the King of Dohwa to go into the battlefield to fight the Zahard forces. In the end, their father died in the battle. After their father's death, Khane and Dowon trained so hard to become Rankers to fill the empty spot their father left behind.

After becoming a ranker, Khane and Dowon quickly become one of many outstanding Rankers from many countries who opposed Zahard to become king of the tower. In order to stand up against Zahard and 10 Great Families, these countries will send their outstanding rankers to receive special training under the masters at FUG. Khane and Dowon also were sent to receive training at FUG. They were trained under a master/teacher who knows the story of a great man and woman (possibly refers to V and Arlen Grace) and also the story of how FUG was created. Their master also knew about Arlene's prophecy.

Before her sister was sealed away at the Wall of Peaceful Coexistence, Khane spent her time with her sister in their house. Khane has convinced Dowon not to seal herself within the wall and stated that the people are just simply exhausted and tired of the war. In the end, Dowon said that she doesn't mind as long as it can bring peace. After Dowon was sealed at the Wall of Peaceful Coexistence, Khane stayed to protect the people of Dohwa which later eventually become people of the wall.

Tower of God: Part 3 - The Wall with a Sleeping Forget-Me-Not
She visits the chamber where her sister is visiting daily, but the day Kallavan infiltrated the wall she was denied access. She was later visited by Kallavan, with him trying to convince her to undo the seal, but she refuses. Kallavan further tries to influence her but to no avail. She is at a later point arrested by Teb and put on trial by Chairman Koer for collaborating with Kallavan, which breaks her resistance and she joins Kallavan in order to undo the seal on her sister.

Appearance and Personality
She has pale skin with long flowing pink hair and pink eyes.

As shown, Khane's mot defining trait is her deep love and devotion to her sister Dowon. As shown where she would loyal stay in the Wall of Peaceful Coexistence for centuries and regularly visiting her sister's seal and give flowers to her in remembrance to her. Dowon herself feels strong resentment for the people of Land of the Peach Blossom, both for the people of ancient past who agreed to seal away Dowon and their current descendants who have begun despising and hating her sister despite her efforts as a war hero and began using her as a scapegoat for their frustrations over the state of their kingdom. Later, with encouragement from Kallavan, Khane would choose to betray her people and free her sister from her prison despite it directly going against her sister's will due to no longer seeing any point in continuing to protect their people and kingdom due to the gradual loss of their dignity and pride as a nation after being defeated by the Zahard Empire and segregated to the Wall of Coexistence and of how they now hold Dowon herself in contempt and returning her selfless sacrifice with ungratefulness.

Powers and Abilities
She is confirmed to be a ranker, with the same type of flower Shinsu as her sister Dowon, as it is a trait of their family. Although she admits to not having fought for ages, Khane still proved to be powerful enough to effortlessly dispatch the guards in her way when she decided to free her sister, with even Kallavan admitting to being impressed by her ability to make it to him without a scratch and so quickly.

 * (To Kallavan) "Mind your own business. You don't exactly seem like the person who'll bring us the peace my sister hoped for either."
