Chelsea is one of the newest members of the assassin’s group, Night Raid. She is an assassin working for the Revolutionary Army, having successfully carried out countless missions. While she is somewhat aloof and carefree when not on the job, she is also extremely objective and is often quite blunt when voicing her opinions. Her town was eradicated by the Empire upon suspicion of harboring rebels.
She has a mischievous personality, but this may be only an act. She has also has a cold and calculating side which can often lead to her making a blunt (but accurate) analysis of a person or situation. Chelsea is shown to have good intentions and tried to help the Night Raid members to become more realistic, as she was shown to deeply care for them and didn’t want to lose them like she lost her old team. She is shown to have a love for lollipops as her Teigu was filled with them and Chelsea is usually shown having one in her mouth.
Chelsea seems to insult both Sheele and Bulat at first in episode 12, which ticks off Mine and Tatsumi. However, she later shares with him that the last group she was with died except for her, and was hoping their unit cohesion was strong so they could assist each other and survive.
Her Teigu, “Gaea Foundation,” is a cosmetics box that allows her to instantly change her appearance and build at will.
Chelsea is a veteran assassin who is on equal footing with Akame in terms of experience and number of kills. In addition, she was built up as one of the most genre-savvy characters in the series.
Despite this, she is killed off on her first major mission with Night Raid which she took an active role in. Although in her defense, she was killed as result of a combination of unforeseeable factors.
