Subaru

About
Subaru is an experienced Blade from the past who served as Haruka's mentor. She is a serious individual with strict discipline and great devotion to the Crescent Moons and their ideals, as well as her master, the Dragonian of her original era, though she was still a caring mentor for Haruka. Despite experiencing many traumatic events following her defeat against Ittou Hagane, she managed to stay utterly resolute in her mission. However, it did make her colder and harsher, particularly when faced with what she considered to be complaisance from her modern associates.

Skills
She is a veteran Blade, and as such possesses great fighting skills as well as a wealth of sexual experience. In combat, she wields a katana and her attacks are empowered by ice, and she has shown to be extremely precise with both, able to hit a precise spot with the former and incapacitating large groups with the latter even after the loss of her arm. Though it was lost forever, the Crescent Moons did provide her with a replacement mechanical arm that can even pass as normal when covered up. Her special attack Ice Thrust Impact takes away a percentage of the enemy's remaining health.

Takamaru
She initially finds him too weak for her to accept him as her master, but after seeing his devotion both to her and the rest of the Crescent Moons, she starts growing attached to him, with his qualities reminding her of her original Master to whom she was very close to.

Haruka
Subaru has long been the mentor and comrade in arms of Haruka. Though she was strict with her during her training, they were quite close and she along with the Dragonian respected her wishes to not undergo the full Dragon Ritual.
