Elfriede "Sakamoto" Cabrera is a attack class sinner, the daughter of Uwe Cabrera and one of the companions of the protagonist.
Elfriede is a very mature person even for her age, considering herself more experienced than most of her fellow sinners (for much of Mattias's dismay), she claims that her ultimate goal in life is to surpass her father one day to which her father gladly waits.
The protagonist and Mattias first met her during their search of a mysterious girl that was apparently causing troubles to the Fraternity when she was getting "bullied" by two older sinners until she scared them away and them walked away but not before scaring Mattias with her mature attitude.
During a secret operation led by Natalia "9" Woo of OPS, they are attacked by the infamous Abel from the Hourai Panopticon and she is the first one to attempt to hit him but fail miserably and is knocked out along with her father.
After either Ann or Hal dies during an invasion on the panopticon, she tries to comfort the surviving sibling after Ann/Hal swears revenge against her/his sibling's killers but manages to calm Ann/Hal down for the sake of her/his fallen sibling.
Later, she led the reinforcements sent to the Nog Panopticon during an invasion from the Hourai Panopticon and its allies, after getting intercepted and barely surviving the enemy attack, she is one of the first to feel that they were betrayed by someone.
After returning, she begins to suspect Carlos was the traitor, mostly due to his shady personality and the fact that he wasn't present during the battle, when he returns to the panopticon, he claimed that he went to the remmains of Nog to pay his respect, however, she still had her doubts about him.
When the traitor was exposed and arrested and Beatrice was kidnapped by Hourai sinner Abel "Strafe" Balt. she, alongside her father, Mattias, Carlos, Natalia and the Protagonist were the ones sent to rescue her.
