Hokoto – Sister
Hokoto is the eldest sister of Nanase. She had a very happy childhood. They were close family, and they trained diligently in the legendary Mizugami style of fighting. This all comes to an end the day that Kairi suddenly disappears without a word. Hokuto seeks to find him, but her clan warns her that Kairi is a danger to the clan, and orders her not to attempt a search. With no further explanations provided to her, Hokuto defies the orders of her clan and travels the world to find him, with her lover Hayate by her side.
Kairi – Brother
Kairi is the eldest brother of Nanase. He is a student of the legendary Mizugami style of fighting. He loved his sisters and would do anything to protect them. One night he began having nightmares in which he harmed and even killed them. He began to fear that this would come to pass in real life. With his mind beginning to fray, he left his clan in order to protect his loved ones. He wandered the world, and as he did, his memories became more tattered and broken, slowly replaced by the nightmares he continued to experience.
