Hannah England is a student at Luna Nova Magical Academy, where she is frequently seen in the company of Diana Cavendish and their mutual friend, Barbara Parker. As a student, she hails from England and wears the standard academy uniform consisting of a dark blue skirt and vest over a white long-sleeved shirt, paired with a dark blue tie and long socks of the same color. In terms of appearance, she is of average stature with wavy auburn hair that she typically keeps tied up in a ponytail with a yellow ribbon, complemented by hazel eyes and somewhat thick eyebrows.

Initially, Hannah is characterized as a bully who takes delight in picking on witches she considers weaker or those who do not come from magical lineages. This antagonistic behavior is most frequently directed at Atsuko Kagari, often referred to as Akko, whose lack of magical competence and admiration for the performer Shiny Chariot Hannah views with scorn and mockery. She is generally disrespectful towards Akko and her friends, and she also judges her own friend Barbara for secretly enjoying the Night Fall book series. Despite this mean-spirited exterior, she is not portrayed as sadistic, and she possesses a notable fearful side. In dangerous situations, such as when facing monsters or venturing into treacherous locations with Diana, Hannah often becomes easily frightened and cowers, contrasting with her usual smug demeanor.

Hannah's relationship with Diana Cavendish is central to her role in the story. She begins as a sycophantic follower, acting as a loyal assistant and speaking on Diana's behalf to highlight her prestigious family background. However, this dynamic deepens over time, and Hannah gradually comes to view Diana as a genuine friend. This evolution becomes particularly evident when Diana leaves the academy, an event that leaves Hannah devastated. This loyalty marks a turning point for her character, as she and Barbara ultimately thank Akko for helping Diana return to Luna Nova, admitting it was something they could not accomplish themselves. By the end of the series, Hannah has reconciled with Akko and the two become friends.

In terms of magical abilities, Hannah possesses the standard magical wand used by all witches at the academy. She has demonstrated proficiency in offensive magic, such as casting a lightning spell to attack a dragon. She also owns a magical stopwatch that features a fairy construct attached to it, which moves the clock hands. In the manga adaptation, she further demonstrates her skills by using magic to manipulate the trajectory of a volleyball during a game and conjuring a chain with a shackle to capture a creature.
