Hozuki is a significant supporting character from the anime Witch Craft Works, primarily recognized as a dedicated guardian and classmate of the main heroine, Ayaka Kagari. She is a teenage girl with an appearance marked by gray eyes and short, blonde or yellow hair that reaches her ears. Her attire typically consists of a school uniform complemented by knee-high socks, and her design features an ahoge, a single strand of hair that stands out. One of her distinct visual traits is that she is often depicted with only one eye showing.

Hozuki’s role is deeply intertwined with the social development of Ayaka Kagari. During their time in middle school, Hozuki, alongside her friend Touko Hio, acted as one of Ayaka’s primary caretakers. In this capacity, she helped the powerful but socially isolated Ayaka learn how to interact with society. Her responsibilities function on a level similar to that of a manager, overseeing Ayaka's daily interactions and well-being.

Her dedication continues into the present story as she becomes a key figure in the group of students devoted to protecting Ayaka. She is the head of Ayaka Kagari’s official fan club, a group that actively works to shield her from what they consider "bad bugs" or unwanted nuisances. Her commitment is not just that of a fan but also of a responsible peer, as she holds a position as a member of the student council. This dual role as both the leader of a fan club and a member of the student council demonstrates her organized and proactive approach to ensuring Ayaka's safety and maintaining a proper environment around her.

Hozuki’s personality is defined by her loyalty and a strong sense of duty towards Ayaka. Her actions are motivated by a desire to protect Ayaka from disturbances and to help her navigate the social world of school life. Her key relationships are primarily with Ayaka, to whom she is fiercely devoted, and with Touko Hio, her partner in their shared history of caring for Ayaka since their middle school days. While her own individual abilities are not the focus, her influence and notable power come from her social standing as a student council member and her leadership of the fan club, which allows her to mobilize others in her mission to protect Ayaka.
