Siri

Siri is Van Maximo's bodyguard and most capable assassin. He found her as a young girl, after killing her abusive father, he raised her to become a ruthless killer. Maximo eventually had her join SENTINEL where her talents made her a natural addition to the Black Legion which 
trained her as a spy and an assassin. As Maximo intended, she was 
eventually assigned to the 43rd Legion to watch over him. Since she had
 always been his agent from the beginning and regularly fed positive 
reports back about him.
Having served him since childhood, Siri is 
completely devoted heart, mind and body to Van Maximo. While she served
 all of his needs, including sexual, she was actually madly in love with
 Maximo's enforcer Luca with whom she was often paired during missions. 
Despite her obvious infatuation with him, the dull Luca never looked at 
Siri as anything more than a valued comrade. Maximo is aware of this 
attraction and finds it hilarious and will sarcastically advise Siri on 
what she can do to catch Luca's eye.
