Ashlin Graham: She is the older sister of Aster Graham, previously when they were young she has the same rank as Aster Graham but after he was transferred to the Assault Drop Unit thus she was promoted through the rank quite easily as Aster is no longer Mech unit with her this as she was given the command to lead the company herself which later Aster would return to afterward.

Chris: One of the soldiers that fought in the Assault Drop Unit that lead a frontal assault directly on the enemy frontline head-on, he is one of the private who served together with Aster but later on when they met again he will have the rank of Lieutenant Corporal and leading the squad who will be under his command.

Elia Graham: She is a cousin to Aster and Ashlin to them she is like a young sister due to her personality of being a bit spoiled and tend to cling to either one or two of them but mostly when she in public she always distanced to them as her discipline was drilled to her as not to embarrass the family.

She is one of the ace pilots of the MIU after Ashlin becomes the leader of the company even though she looks ignorant and easy-going but her skill is never been doubted during her time in the battlefield so she was given custom pilot and off duty outfit she wanted which has rabbit decoration on it and was made official as her characteristic clothing.

Lucy Q-AI (Quantum Artificial Intelligence): An AI who managed to obtain a free will unlike its predecessor or its kinds, normally this kind of AI would be destroyed because it threatened humankind of possible revolt and existence that the higher up once ordered the search and destroy had caused the human race to a great civil war that almost torn it apart but because the few numbers of the sympathizer the war were won by those who feared them thus the AI was later then be downgraded to normal operating AI with almost no free will to the public.

Lucy and its remaining kind were carefully protected by the remaining sympathizer as they get in cover from the government except those who are truly loyal to the government and Aster were one the later ones.

Oriel Scepteris: She is one of the Lieutenants who is part of the MIU company serving under Ashlin's command before Aster returned to the company at first she felt extreme disgust of how Aster was disrespect towards Ashlin previously which made her gloat at him, she was first entranced to join the MIU company because a certain event where she meets the silver mech the first time that had saved her life during a colony attack when she was young but sadly she did not recognize Aster as that very pilot who saved her later on knowing the reason of his retirement out of the company put her in emotional guilt that would haunt her every time she is with him.
