Was looking through Haruka's CS again and this made my mind laugh at the possibilities:

"Will of Steel

Haruka's will of steel is something that is believed to be inherited by the Hagane blood that flows in her veins. She is stubborn like few and once she gets an idea into her head, she will not stop until her goal has been accomplished."

For some reason I've now got in mind a Naruto-Sasuke kinda relationship where Haruka makes it her goal to be Ryuu's friend. lmao.
