Subaru  

, スバル

Subaru was a skilled Blade who served as Haruka's mentor in the past. She was very disciplined and devoted to the principles of the Crescent Moons and her master, the Dragonian of her time. Although she cared for Haruka, she remained strict and serious. Despite facing many difficult events after losing to Ittou Hagane, Subaru stayed determined in her mission. However, this experience made her more cold and harsh, especially when she felt that those around her were not living up to her expectations.
