N!

grey coat

doesn't like yandere

N is kind, empathic, open, nervous and sometimes awkward in communication. He always wanted to make friends, or at least get recognition from his colleagues. He himself admits that he does all this dirty and bloody work only because he wants to be useful. Of all the killer drones, the most careless

Unlike female demolition drones, his legs look quite human and stay securely on the ground. His silver hair has a parting on the left. The eyes are yellow, and there is a black indicator on the head with five yellow sensors that show the status of the drone's five vision systems.
In combat mode, killer drones are distinguished by their grin with sharp teeth, they have sharp metal wings and claws, and their eyes are replaced by a large neon yellow cross. En wears a dark gray coat with a fur collar, and on his shoulder he has a yellow headband with a skull painted on it, the logo of demolition drones. And on his head is a black pilot's cap, which hints to us that he had or has flying skills.
As a butler at the Elliott Mansion, En wore a black tuxedo, a black ribbed helmet, and had neon-white eyes.
