Aoi is a mysterious, self-proclaimed 16-year-old girl who Otoo meets on his travels to find his missing wife. He brings her back to Wagnaria where she starts working as a waitress and living in Wagnaria's attic. While she has great confidence in herself, during work she is an unhelpful troublemaker who gets yelled at by other staff members, especially Souta. Since she is in training, her position among the staff is low, which she complains about. She is bad with dealing with Souta's constant complaints about her, but she does write down some of his suggestions (along with idle complaints). She yearns for the idea of having a family, especially towards Otoo whom she sees as an ideal father figure, and goes as far as to apply to be adopted by him. Her favorite food is natto. It is later confirmed that she had indeed ran away from home, and Yamada was a fake name. Souma finds this out and continues to try and keep them from meeting due to him realizing Aoi probably has her own reasons for having run away.

Takumi is the little brother of Tokiha Mai.
Mashiro first appears unnamed during episode 2 in the flower garden with Fumi when Mai Tokiha passes by and asks them as to where Mikoto Minagi scampered off to. Mashiro and Mai formally meet in episode 3, when Mashiro tells Mai that she is gathering the HiMEs to defeat Orphans. Mashiro tells her to decide what she wants to do on her own, which later becomes a recurring theme in Mai's story. Mashiro's true body is revealed in episode 25, encased in a crystal star. She is also further revealed to be the winner of the previous HiME carnival as well as the former user of Kagutsuchi, Mai's Child. In the final episode, Miyu's anti-materializer frees Mashiro, and she floats up to the Crystal Shrine. She revives the fallen HiME, resurrecting them and their loved ones, and restoring their HiME powers. In the ending credits, Nagi and Mashiro (still in a wheelchair) enter the large doors at the far end of the library. Powers In episode 21, Mashiro displays two abilities: the ability to create a barrier preventing eavesdropping, and the ability to transform into a Child. As Fumi's Child, Suishou, she radically changes appearance and wields a double-sided blade, and bears Kagutsuchi's crest of three tomoe on her robe. In her true body in episode 26, she is able to appear in spirit form to multiple people, revive the dead, and restore the powers of fallen HiME. (source: Wikipedia)
Marie's protégé. After Marie saved her life using alchemy, young Elfir Just knew she'd follow in our goofy alchemist's offbeat footsteps. Elfir may be young and naive, but rumor has it that she might be more capable in some matters then her eccentric mentor. Source from Atelier Marie and Elie Zarlburg Alchemist Volume 2.
A high school student. She tends to be strict and somewhat unfazed at the strange behavior of her co-workers, except when they fail to do their jobs properly. Hana tends to punch the manager in the face and encourages Higashida to do the same so he does not become as miserable as the manager. Despite being rough on the exterior, she can quickly change her personality to look friendlier (albeit to customers only). She enjoys making chocolates, although they are terrible enough to make people "meet Saint Valentine from down the Heavens". (Source: Wikipedia)
