First Contact with Class VII
Millium first meets Class VII on a special training trip to Nord Highlands. She helps them solve a crisis between the Empire and the Republic and becomes friends. Later, Giliath Osborne arranges for her to transfer into Class VII officially.
At first, the classmates are unsure about Millium, but her cheerful personality quickly helps her fit in. She is happiest accomplishing things together with her friends.
The Civil War and Reunion
During the civil war, Millium and her puppet Agartram help Rean, Alisa, and Gaius regroup in Nord Highlands after Class VII is scattered. She fights against Altina Orion, who pilots a similar puppet called Claiomh Solais, nicknamed "Kuu-chan." Millium wonders if Altina is her sister—and the truth is revealed later.
Her new super move, "Galaxy Cannon," sees her and Agartram flying into space and firing a giant beam back at Earth.
Working with the Ironbloods
Millium graduates from the academy early thanks to her achievements. She returns to her job as an agent but continues to join missions with Altina and keeps meeting Class VII. She cares for Altina as a big sister and always brings some fun wherever she goes.
The Truth About Her Origin
Millium is one of the "Oz" type artificial humans, built to become the sword to defeat the "Black Holy Beast." This means she has a fate she cannot escape, and she herself cannot grow much older. In a brave moment, she protects her friends in front of the "Black Holy Beast" and sacrifices herself, turning into the "Great Sword of Emptiness" to save Rean and the others.
Becoming a Sword and a Spirit
As a sword, Millium becomes the new weapon for Rean's partner Valimar. Later, she appears as a spirit inside the sword, staying cheerful and supporting her friends in spirit form. She even spends time with Eusis before the final battle, surprised at how honest he became after losing her.
The Final Battles
In the end, Millium helps Rean in an epic battle against strong foes, including Giliath Osborne and the Black Holy Beast. In one ending, she disappears along with Crow after their roles are finished. In another, after the curse is defeated, her soul is brought back to the real world by Franz Reinford using a backup body. Millium regains her life, and finally, all of Class VII can be together again.
She later attends Prince Olivert and Scherazard's wedding, wears a matching dress with Altina, and happily catches the wedding bouquet.
Later and Extra
In later stories, Millium gets a new mechanical partner after her original is destroyed. She continues to work with friends like Eusis, Rean, and Altina.
Even though she doesn't appear in the newest game, she keeps meeting Altina as a loving sister. Her body keeps growing, and she starts to worry about things like weight and appearance—just like a regular teenage girl.
Millium is a powerful front-line fighter thanks to Agartram. She has high physical defense and attack power, but her HP and speed are low. Give her accessories that boost those to make her super strong.
Her attack element is "Steel," ranking S, and her fixed elements are Mirage x2, Earth x1. It's best to use accessories and equipment that boost those stats.
She is always ready to protect her friends, no matter what!
