Chelsea

Chelsea was one of the two new members that joins the Demon Army. She later died in the line of duty.

Appearance
Chelsea had pale skin, auburn hair (pink in the anime), and red eyes (pink in the anime). She wore a butterfly headphone accessory on her head. She wore a vocalist-like clothing consisting of a white long sleeve shirt with the collar tied with a red ribbon under a black vest a red checkered mini skirt, and black leather below-the-knee boots. She carried her Teigu, Gaea Foundation, wherever she went. She was almost always seen sucking on a lollipop.

Personality
Chelsea had a mischievous personality, but this may have been an act. She had a cold, calculating side which can often lead to her making a blunt (but accurate) analysis of a person or situation. In the end, she was shown to have good intentions and tried to help the protagonists 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 was shown to have a love for lollipops as her Teigu was filled with them and she was usually shown having one in her mouth.

History
Chelsea worked under a cruel viceroy who took joy out of hunting people. Under this oppression, she started becoming nihilistic until she found Gaea Foundation, which had been stored away because no suitable owner could be found. Using the Teigu, she assassinated the viceroy, who was replaced with a kind and competent one. Realizing that she had caused a change with her Teigu, she ended up joining the Demon Army.

Teigu
Chelsea possessed a Teigu named "Gaea Foundation" that allowed her to change her appearance at will. While her Teigu is a support type, Najenda has stated that she had gotten almost as many jobs and assassinations as Sidero, suggesting that Chelsea was quite skilled in combat (or at least assassination).

Other Abilities
She mainly used stealth in battles, waiting for her enemy to get close before killing them in a single hit by using needles. She excelled at deception to trick people and let their guard go down.
