Honoka Sawada is a second-year student at Katagiri Senior High School. She possesses waist-length black hair with bangs and chin-length strands framing her face, blue-grey eyes, and a mole under her left eye. Standing about a head shorter than Izumi Miyamura, she shares a noted resemblance to him, particularly in the anime. She consistently wears her school uniform with her shirt tucked into her skirt, gray Converse shoes, and gym shorts underneath.

Honoka displays a clingy and deeply affectionate demeanor towards Kyouko Hori, often hugging her out of jealousy or excitement. This attachment fuels her view of Izumi Miyamura as a rival for Hori's attention, leading her to frequently push him away when he's near Hori. Her feelings for Hori are romantic, establishing her as a canon WLW character. Though initially perceived as having a crush on Miyamura due to stalking him at school, it's later revealed she monitored him solely out of jealousy over his closeness to Hori.

Her personality includes introverted tendencies and difficulty connecting with classmates, coupled with a pronounced fear of adult men (androphobia). This phobia causes her to freeze, hide, or flee when approached by men. She startles easily, particularly around loud or outgoing individuals like Shuu Iura, and actively avoids frightening situations. This fear stems from the loss of her beloved older brother, leaving her profoundly lonely. After his death, she sought companionship by climbing through Miyamura's balcony at night, gradually coming to see him as a brotherly figure and hiding behind him when uncomfortable around other men.

Over time, Honoka develops significant trust in Miyamura, aiding her acclimation to his male friends. Their relationship evolves from rivalry into a sibling-like dynamic, reducing her isolation and fear. This growth marks her broader character development as she learns to navigate social interactions more comfortably.
