Amnesian
Probably derived from Kannanzuki but Miko. Himeko, a pious Christian in the church, lost her mother, father and older sister Chican, when she was younger. When he removes the chapel, he meets a girl like his sister on the face and name pierced by the sword. Chemeco thanks to God for giving her another chance to see someone like her sister, but then another girl attacked her, who says that she has a "dragon cry" inside her body. Chican promises to protect it.
