Ada Clover

Ada Clover (エイダ＝クローバー) is the oldest child of the Clover family, the child of Relius and Ignis Clover, and the older sister of Carl Clover. Her soul is sealed within the Nox Nyctores - Deus Machina: Nirvana. Level-headed and kind, Ada calmly watches as her brother tries to find a way to reverse her condition.

Appearance
Ada was a tall young girl with blonde hair that comes down to her lower back, bright blue eyes, and fair skin. She was always seen in a long navy dress that came to her ankles and had multiple lighter blue stripes running vertically across it. The dress ended in frills, had white cuffs at the end of its long sleeves, and a white cravat with a singular purple jewel in its center.

Personality
Despite being largely mute within Nirvana, Ada's personality shines through. According to Carl, she is witty, feisty, kind, loving, and enjoys vulgar jokes. Ada is a voice of reason to her younger brother, and has been known to get upset at certain events. As Carl's morality slowly yet surely leaves him, Ada has been shown to deny his orders to kill, and will even protect others from her younger brother. Despite this, she will still follow him loyally.

Powers and Techniques
Although as a human she was never seen fighting, Ada has an incredible soul since she is not just the core of Nirvana, but is also in control of most of its actions. Her identity has seemingly permeated throughout the Nox, and her remarkable willpower allows her to outright defy her master's wishes. Within Nirvana, she gains all of the Nox's abilities. She's immune to seithr, can cause wounds to the soul with her nails, and is capable of generating balls of Ars Magus to launch at opponents. It is shown that she is also immune to Phenomenon Intervention.

''Carl's sister. She has hair blonde enough to rival even Carl's. She is kind, and loving, but parts the world of mortals, when implemented into the Nox Nyctores: Nirvana.''
