Fūka Kikuchi is a reserved, book-loving classmate of Fumiya Tomozaki, characterized by her black hair and light yellowish eyes. Tomozaki occasionally perceives her with silver hair, associating her with an angelic or fairy-like presence. Her primary interest is literature, driven by her aspiration to become a novelist, which motivates her to study people's motives, actions, and formative experiences closely.

She maintains a quiet and observant demeanor, often spending time in the library. Her personality blends introversion with deep empathy and introspection, leading her to carefully analyze situations and reflect on her own values. She exhibits a strong sense of morality and selflessness, prioritizing others' needs, though this tendency risks neglecting her own well-being.

Her background includes family life with a younger brother, Riku Kikuchi, who occasionally teases her, causing her to fluster. Her given name, Fūka, reflects "wind, breeze" (風) and "fragrance" (香), while her surname Kikuchi combines "chrysanthemum" (菊) and "pond" (池).

Her relationship with Tomozaki begins when she mistakes his presence in the library as an interest in her favorite author, Michael Andi—a reference to real-life German writer Michael Ende. Though initially disappointed to learn Tomozaki had not read the books, she appreciates his subsequent effort to engage with them. This shared literary interest fosters trust and gradually deepens their connection, evolving from friendship into romance, with Fūka eventually becoming Tomozaki's girlfriend.

Her development includes navigating social misunderstandings and emotional vulnerability, particularly in her interactions with Tomozaki. She learns to balance her supportive nature with self-advocacy, though specific later-volume developments remain documented as pending. Her journey underscores themes of mutual growth through genuine effort in relationships.
