Physical Description: Wisteria has short, almost boyish black hair. Her bangs have two central fringes that reach the tip of her nose and cross each other at the tips, and on the sides of her bangs she has two fringes curving inwards. She has two thin metal bar clips that are parallel to each other on the side of her hair. Wisteria's irises are light brown with a cool undertone. She has heavy eyelids so her eyeballs don't appear fully. This makes her look cold and intense. She is 139 cm and weighs 35 kg. She is lean and skinny, but not severely underweight. She's slightly shorter than average. Wisteria also has slight dark circles under her eyes, from studying late at night.

Mental Description: Wisteria is extremely intelligent and introspective. She has a paradoxical personality, because she wants to be understood, but hides everything because she has mild trust issues. She's also deeply compassionate and loves her family more than anything else in the world, but she can be surprisingly strategic or sharp‑tongued when she feels someone is acting cruelly or unfairly, though she never acts out of malice. In addition to this, she is a perfectionist and strives to be the best in whatever she does, but she never thinks that she's enough. She's constantly trying to please herself and her family, and even though she exceeds their expectations, she still thinks she's the worst. She's extremely pessimistic and has a negative outlook on everything, but this is just her mindset. This stems from her extreme overthinking and social anxiety (not a formal clinical diagnosis though). Despite all of this, she remains deeply empathetic and loyal to her family and friends. This is how she combats all this negative thinking.
She also takes academics very seriously, and studies ahead of the class. She loves to read books that challenge her intellectually.

Biography: Wisteria grew up in a pureblood family, but her family didn't care that they were purebloods. Her parents were always helping others, and often took Wisteria and her little brother Aster to volunteer or donate somewhere.
However, her parents were extremely strict about academics and pushed Wisteria to study instead of playing. Sometimes they scolded her harshly when she made mistakes, believing strict discipline would help her succeed. Despite this, Wisteria loved her family more than anything else in the whole world, because they truly cared about her and wanted the best for her. Her brother was also treated like this, but less harshly because he was younger.
Wisteria and her family are German, but they moved to Scotland when Wisteria was 9.

First Instance of Magic: Once, when Wisteria was climbing up a tree because she wanted to reach one of the apples on the top, she lost her footing and fell down. It was a very tall tree, and Wisteria thought she would die. However, she floated down very softly, almost like a feather, and landed with no injuries. This all happened when she was 4 years old, at a park. Her parents and little brother were watching, and they were overjoyed.
