So if you have to make dolls and masters together, why is there an uneven number?

Personality: Charles is above all a professional, putting his job before himself. Since his job is police sergeant, that means he's often putting himself in danger to save others. Underneath the iron shell is a side few people glimpse outside of his home: His true compassion.
Backstory: At 20 Artemis enrolled in police academy, eventually graduating on his 21st birthday. Since then he lives alone, spends his time either working or reading, and his solved over 80 cases ranging from vandalism to homicide. He doesn't have anybody he could call a real friend, but he gets along with almost everybody on the force.
Skills: Firearms, unarmed defense, interrogation, investigation, cooking.

Doll:

Name: Melody
Gender: Female

Personality: Melody is normally gentle and happy, a sweet girl who tries her best to be brave for her master, but at the sight of blood (Or when she gets damaged enough), she loses all of that gentleness, becoming a single minded killing machine who's only goal is to protect her master at all costs. Until she calms down from this state she is dangerous to everybody else, seeing anybody approaching her master as a direct threat, and treating a child with a doll as harshly as a grown man with a sword.
Abilities: Normally Melody has the power to create shields and swords out of energy. Normally she only uses her swords on Puppeteers, but when she "loses her soul" she can turn those blades on anyone.
Weapons: None (Her swords are created and controlled by her magic. she has no permanent weapons.)
Misc: Melody has a perfect singing voice, which is what gives her her name.
