Mana Takamiya

After the sealing of Yoshino, she was assigned as a replenishment personnel to the Tengumai Garrison with the rank of Third Lieutenant. She is also a seconded employee from DEM Corporation, and her call sign is Adeptus 2. She is a girl around 14 or 15 years old, with a smart-looking face and a tear mole under her left eye, and her hair tied at the back of her head, bearing a similar atmosphere to Shidou. She often uses peculiar honorifics such as "Not impressive at all" and "It's decided, isn't it."

She is said to be among the top five in the world in handling manifesting devices, and indeed, even ten AST members including Origami cannot match her. Additionally, she wears a CR-Unit developed by DEM Corporation, which requires her entire body to be treated with magical power. Despite her young age, she possesses abnormal combat abilities, but the cost is significant; according to Rei's analysis, she is diagnosed to live only about another 10 years. Moreover, she has lost most of her memories for some reason and was unaware of her own body's condition.
