Thief

Thief (シーフ; Shīfu) is one of the main antagonists in Tsubasa no Higeki. He is quiet and confident; most of the time independant, but more violent than everyone else. Thief would be described as 'tsundere'; except he isn't tough, but quiet. He would threaten to kill anyone in his way, or anyone hurting his allies (Crow and Ritsu). Thief seems to have feelings for Ritsu, as seen in chapter -no#- when he nervously told her to hold on if she was afraid. Thief is also seen overprotected as he would protect her and Crow with his life; he isn't afraid to take all risks.

Childhood
Thief ran away from home when he was 8 years old. Having lost the only joy of his life; his twin brother, who's name he doesn't remember due to major brain damage from a severe disease. Derp Devestated him enough to give up on life. He left home when his parents were at work and wandered around the city, in hope of finding his brother or at least someone who will care for and about him just as his brother did.

Until the day he met a boy the same age as him running along the street with bread in his mouth, he didn't look stressed at all. That boy was called Crow, who also apparently doesn't have a home either. They grew up together for months, moving everyday and having to steal off shops and people to survive. As they travelled, they eventually found a spare room in what seems to be a half-abandoned building. The two stayed there and refered to it as 'home'.

One night, Thief decided to go exploring around the city, if there was really anything worth looking at. As he was walking, he saw a girl sleeping in front of a shop. She, too, looked like she was homeless. But there was a strange aura about. Curious, and in pity, he stopped walking and carried her back.

Promising himself not to let Crow or Ritsu down, he swore that he won't lose any loved ones ever again. He wears Ritsu's red scarf showing that he's accepted her friendship.
