She has long purple hair and yellow eyes. In her first appearance, she was dressed in black and wearing a choker with a teardrop-shaped jewel. After being becoming a teacher at Sankai High, she'd wear many different dresses, and would occasionally wear her teardrop-shaped jewel again whenever she is dressed in black.
Though she is kind and caring, she can be greedy, sly, irresponsible and messy.
She enjoys drinking alcohol.
Annette is descended from a “witch” of Medieval France, who formed a contract with a Shinigami for the Scrying Orb, which was passed down on her family for generations.
Her French grandmother met a Japanese tourist who would become her grandfather, and they moved to Japan. And so, Annette was born 1/4 French and 3/4 Japanese.
She is first seen working as a fortune teller with the scrying orb, in a shopping mall as a part-timer. When Sakura informs Rinne about her and her crystal ball, he and Rokumon recognize it as the scrying orb. As the Shinigami association tries to recover Shinigami tools that ended up in the living world because they can give a negative effect on whoever possesses them, Rinne went to seize it. But as the orb warned her of his arrival, she managed to escape.
She quit her business and transferred herself as a new teacher to Sankai High, and much to her surprise winds up as Rinne and Sakura’s new homeroom teacher. She reveals that the scrying orb showed her becoming a teacher, and other glimpses of the future led itself to be brought by Rinne to a Peep Ball Maintenance to be repaired and taken back to her owner.
She would get involved whenever she does some mischief, tries to make sure she remains being loved by her students, and her scrying orb would show glimpses of past and future situations that can be surprising and give comical twists. And since it remains a valuable lost Shinigami tool, it would be targeted by many, but she is not bent on handing it over.
Her grandmother and mother tend to be absent at home, always going to the hot springs, and upon returning home, her grandmother would hit her granddaughter in the head whenever she does something wrong.
Among the ones trying to seize the scrying orb is Sabato, who in his first attempt tasked Renge to steal it to sell it, while Kain wished to recover it, so Renge tried to seize it herself to impress her crush, but it would remain with her owner in the end.
Masato discovered it while trying to play a prank on Rinne and cursed it, causing the images of the future to be tampered, guiding the person in the wrong direction. A fight between a demon and a witch ensued then, while she had to find through her mess a key to a white magic small box (which she had to find as well through her mess) to clean her orb with a special cloth to break the curse.
At one point, she took a witch promotion test which took place at a campground, and as the scrying orb reveals that she will be absent at the next ceremony, it seemed that she would pass and no longer be a teacher, which left her students sad. That test consisted in summoning and capturing a fairy, and after some delirious outcomes, she eventually doesn’t pass and her absence at the next ceremony is just because she arrived late.
- Scrying Orb (のぞき玉): It shows accurate glimpses of the past and the future. If it's lost, it always returns to its current owner. It seems to have a mind of its own as after encountering Rinne, it led Annette to become a teacher and let Rinne seize it to have itself repaired.
- White Magic Small Box (白魔法の小箱): It contains a cloth that would clean her orb if it’s cursed.
- Demonic Sword (退魔の剣)
- Seeing Ghosts: She is able to see spirits.
Annette relies a lot on Rinne, who suffers many upsets because of her orb and her behavior, but he doesn't seem to hold a strong animosity toward her.
Sakura does not hold any ill feelings toward her although she often sees her as silly.
Both girls love their teacher. They were sadden when she almost quit being their teacher.
Annette hates Masato, ever since he cursed her orb.
- “I won't hand it over for free” (タダで渡す訳にはいけませんね) – Chapter 204, when Rinne says he’ll recover the Scrying Orb
- She and Rinne are quite alike, for both having money trouble, and also her being 1/4 French 3/4 Japanese, and him being 1/4 Human 3/4 Shinigami.
- She and Suzuki do not meet in the manga, since he originally served only as PE coach.
