In Girls' Frontline

 Made by IOP, the highly intelligent tactical human form is the ultimate product of the existing puppet network technology and is equipped with mental programs similar to human emotions.

As the leader of the AR team, like the function of a human commander, but as a tactical humanoid, independent command ability can not be compared with a true commander.
The character is cold and calm, but clear, but the factory is too new, less experience, coupled with rich emotional performance, often caught in the choice of fear and self-doubt. However, in the face of peer trust and responsibility, the mission will be successfully completed.

The M4A1 is the actual commander of the AR team and has a sensitive introverted character. This does not seem to be the quality that a qualified leader should have. In fact, M4A1 has two different personalities: weak and strong. She is trying to overcome this swing to make herself a qualified captain. She and M16 are also teachers and friends. They are usually willing to take care of the team members and are very concerned about the safety of the team members. "How long will it take to become her own mind ..." This line is a true portrayal of her heart.
For this contradictory character, the painter used a softer facial line when designing the character, and there were not many facial elements, looking like a "three girls." However, on the dress accessories, a face towel with sharp teeth, metal prosthetic limbs, and various tactical accessories were designed to reflect the other side of her ability to fight. The shirt on her waist, similar to the M16, is also an indication of the relationship between the two.
