Mail Al Mehelim is a supporting character in the anime Heroic Age. She is a young woman of the Iron Tribe, humanity’s faction in the series, and serves as an attendant to Princess Dhianeila Y Leisha Altoria Ol Yunos, the story’s heroine and the leader of the human forces. Mail is easily recognized by her youthful appearance, characterized by her purple eyes and brown hair that falls to her neck, often styled with a distinctive loop.

Mail is one of twin sisters, with her counterpart being Tail Al Mehelim. Both siblings are identified as possessing notable psychic powers, a rare and valuable ability within the human race. These abilities allow them to assist Dhianeila in various capacities, especially given the princess's own powerful telepathic and psychic talents, which are central to the Iron Tribe's strategy. Their close service to the princess indicates a high level of trust and responsibility placed upon them. The twins are the daughters of Mobead Oz Mehelim, the capable and loyal captain of the starship Argonaut, which serves as the primary vessel for Dhianeila and her crew. Through their father, the Mehelim family is established as a military family deeply dedicated to the protection of the Yunos royal family, and the sisters inherit this legacy of service.

Mail's primary role within the narrative is as one of Dhianeila’s closest aides and confidantes. In this capacity, she is consistently present on the bridge of the Argonaut and during key diplomatic or strategic meetings, contributing to the functioning of the command staff. Her tasks likely involve utilizing her psychic abilities to support ship operations, gather intelligence, or facilitate communication, as is common for such characters in the series' universe. Her twin, Tail, shares these duties, and the pair are often seen together, functioning as a unit that serves and protects their princess. Mail’s relationship with her father, Mobead, is professional and defined by their shared loyalty to Dhianeila, as his primary objective is also the protection of the princess.

In terms of development, Mail remains a steadfast and loyal figure throughout the story, with her character focused on her supportive role rather than a personal, dramatic arc. Her abilities and dedication are a constant asset to the human cause as they navigate complex interstellar conflicts with other races. Her notable abilities are her psychic powers, which place her among a special subset of humans capable of feats beyond normal physical limits. While the full extent of her specific powers is not detailed in all sources, she is acknowledged as part of a twin pair with such capabilities, making her an integral part of the Argonaut’s crew and the inner circle around the princess, who herself possesses powerful telepathic abilities.
