Millium

Millium has the appearance of a small girl with turquoise blue hair of a short length with two antennae like hair strands sticking up. Millium has vivid amber eyes.

In her Special Ops uniform, Millium wears a close-fitting waterproof jumpsuit with exposed legs, matching thigh high boots and a series of belts all paletted in the same colours as Airgetlam. She wears protective guards around her hands and feet. Later on, she later wears the standard Class VII crimson uniform of Thors Military Academy, with a teal tartan pleated skirt, black beanie and lilac cravat. Millium has also attached several badges and stickers across her uniform.

During the October War, she switches to her wartime clothes styled as a sailor uniform with a beret. She wears a long-sleeved monochrome shirt with a belt around her chest styled like a ribbon, with a thin black shirt and brown shorts on the inside, as well as dark turquoise patterned stockings in white boots.

Later on, Millium travels around in her new white and dark blue intelligence uniform with a new beret. The back and underarms of her new outfit are exposed, and she wears black-striped stockings with white boots.

Millium is a cheerful little girl that is usually a ball of boundless energy wherever she goes. She is a bit ditzy and can have no common sense regarding how to act for her age, on multiple occasions summoning "Lammy" in public, but gets better over time.

Millium loves Claire, who treats her like a younger sister, and considers the Ironbloods more or less like family. This can be said about her relations to Class VII as well, most notably Jusis, whom she forms a special bond with during her time at the academy and well after graduation.

Millium also has a habit of realizing things too late. She can however have morbid thoughts to situations as demonstrated when she suggested to Rean that a cookie that she made could have easily been poisoned and could have killed him. She dislikes haunted places such as Lohengrin Castle and panics in situations where she's restricted and unable to call on Airgetlam.

Millium is an artificially created human, a homunculus, that was created in the Black Workshop along with her sister Altina Orion. She was adjusted to link with Airgetlam, a combat shell. Millium gained consciousness in S.1199 when she woke up in the care of Giliath Osborne, Lechter Arundel, and Claire Rieveldt. Altina had not been out of incubation yet, but Millium considered her to be her sister. Her memories of the workshop were erased, and she then joined the group known as the Ironbloods.
