Altina Orion is a mysterious young girl introduced in Trails in Cold Steel II. She is a supporter of the Noble Alliance who goes by the code-name “Black Rabbit,” and manipulates a jet black combat shell called "Claimh=Solais". From observance she shares the same traits as Millium Orion, it was revealed in the civil war's climax that she was an undercover Ironbloods agent. In Cold Steel III, she graduated as one of the main characters in the new Class VII when she enrolls in the Thors Military Academy's Reeves II Campus through unknown reasons.
Altina appears as a little girl with silver long hair tied in two ponytails that danger on the front side, and lawn green color eyes. She apparently wears a dark-grey sleeve shirt with different design line marks, short shorts hidden beneath the long-sleeve shirt, and a diamond pattern in the middle that shows her belly while the mid-chest area is covered. Also with the outfit comes a hoody with two rabbit-like ears. She wears the same color style of boots up to her knees, has a metal armor knee pad on her right, fingerless gloves. Accessories are two gold hair bees around her dangling ponytails, and one around her neck collar; like a cat’s bell. Attach to her outfit, she has a long thread tail with a metal circle shape with three metal tail-feathers from shortest to longest. On an appearance scale, most don’t take her seriously in such a sketchy outfit, but one look at her little; friend, and her cold presence might say something differently.
Despite Altina's little girl appearance, she seems to have somewhat a more mature personality yet all the while emotionless which is the opposite of Millium. She acts seriously with a pre-program behavior of escalating her situation, matter of targets, and objectives as described robotic. But little by little Altina shows emotion within her outer shell, as Rean seems to have her experience more from when he lectured her about her actions. At first Altina was unable to comprehend about her conflicted feelings at while most times, but admits the obvious actions Rean has done to say something he isn’t that causes mis-confusion.
- Like Millium, her name "Orion" has several etymologies upon character and primary affiliation.
- Orion is the prominent constellation visible throughout the world, named after Orion, a hunter in Greek mythology.
- All the Ironbloods (plus Chancellor) are somehow referenced from The Wizard of Oz. In both Millium and Altina's case, the last syllables in their last name is "rion" ="Lion".
- While unconfirmed to be actual sisters, Altina's real name is "Model 0z74", while Millium says she's 'one up' on her; stating she would be 0z73, thus clarifying the aging difference
- That fact that Altina and Millium are sisters while the latter has the irresponsible playful kid side while the younger one is a bit more responsible, similar to Neptune and Nepgear from the Hyperdimension Neptunia Series.
