Description
Aes Machias is a passenger encountered aboard a luxury cruise spaceship traveling from Mars to Earth. He is the twin brother of Alice Machias, and the two are implied to share a single body, manifesting as two distinct personalities within one individual. While the series does not explicitly confirm his nature upon first appearance, narrative clues suggest that Aes is one of the Nine, a group of powerful artificial beings central to the story's conflict.

Personality-wise, Aes presents a gentle and somewhat sensitive demeanor. He is shown to have an appreciation for old-fashioned, sensory experiences, particularly a love for the smell of paper books, which he describes with evident fondness. This interest reveals a thoughtful, perhaps nostalgic side to his character. His reaction to criticism is notably delicate; when the protagonist Rouge recoils from the smell of his books, Aes looks crestfallen, indicating he is easily hurt by negative feedback and may possess a degree of insecurity. However, he also shows a capacity for quiet endurance and a desire for connection, as he patiently waits for Rouge to offer a more balanced opinion. In contrast, his twin sister Alice is described as being reliable and strong-willed but also blunt and poor at communicating. She regards her brother as pitiful due to his perceived weakness, yet she also takes her responsibility to care for him seriously, suggesting a complex, protective, and perhaps critical internal relationship.

Within the story of Metallic Rouge, Aes plays a significant role as a fellow passenger whose quiet presence intersects with the main characters' mission. His cabin is located next to that of Rouge and her partner Naomi. A key interaction occurs when he shows Rouge his collection of paper books, which are an unfamiliar object to her. This moment allows for a small but meaningful exchange where Rouge initially finds the scent unpleasant but then admits she does not hate it, leading Aes to smile. This scene serves to highlight the cultural and experiential gap between different types of beings in the series' world. His primary motivation appears to be personal and unassuming, centered on the simple act of returning books to the ship's library, which belies the larger, more dangerous secrets his identity likely holds. His role in the narrative is intertwined with the mystery of the Nine, and his unique existence as a dual-personality entity is a key element of his development, hinting at internal conflict and the theme of fractured identity.

In terms of notable abilities, the most prominent is his existence as a dual consciousness sharing one physical form with his sister Alice. While the full extent of any combat or specialized powers is not displayed during his initial appearance, the very nature of being one of the Nine implies he possesses abilities far beyond those of a normal human or standard android. The dynamics of how he and his sister alternate control or interact within their shared body remain a defining and mysterious aspect of his character.
