Ruo Eschuck

Childhood friend and Elle's ex-fiancé, he's a professional martial artist. Elle only sees him as a big brother, who gave her comfort when they were younger, however, Ruo is actually violently possessive of Elle and will do anything to alienate her from other men who might take her from him. He tends to put his male groupies up against anyone Elle may like or have a crush on, which makes her very distant from other men.
