Beruka, raised as an assassin committed to executing her cold-blooded duties with no emotion, generally comes off as very cold, stoic, unfeeling and distant. She’s neither sadistic or cruel; viewing killing simply as something she has done all her life and thus something she cannot leave, or possibly as a way to feel needed by others. Due to being fully devoted to her duties as a master assassin, Beruka does not seem to devote any energy towards activities outside of her duties.
