Not much is known of Aki Brightcaster, except that she is a weak mage, and often referred to it. She is currently the Grand Master of Dark Unicorn, her illegal dark guild. She often uses her favorite phrases such as in battle; "Dark Ecriture: Darkness!" to activate her darkness magic. She currently has two other magics, including Darkness, Solid Script, and various kinds of Letter Magic. She is a fangirl to yaoi, and often ships many of the Grand Masters of guilds, and spreads it to many S-Class Mages and Mages. Her combat skills are poor, therefore her using magic 3/4 of the battle.
Her current Partnership within Dark Unicorn is Vladmir Lykos, the co-Grand Master of Dark Unicorn in case if she dies. Other members, Kyla Dragneel (Center, Left) and Solomon Haruaki (Center, Right)
