Kawana Misaki is a third-year high school student blinded in an elementary school accident. She maintains a relentlessly positive and sociable demeanor, showing no wariness toward others and resisting excessive caution. Living directly opposite the school enables her independent commute, aided by pre-blindness familiarity with the campus. Her favorite place is the school roof, where she experiences sunsets through sensory perception rather than sight.

Misaki possesses a remarkably large appetite, especially for the school's katsu curry special. She famously consumed five plates of curry followed by two additional plates of katsu curry in one meal with Kohei Orihara. Her friendly nature draws her frequently to the theater club to support best friend Yukimi Miyama. She communicates effectively with mute underclassman Mio Kouzuki by placing a finger on Mio's mouth to interpret words through lip movements, overcoming communication barriers.

Her blindness once led to childhood suicidal contemplation, but she overcame those thoughts through an unwitting friend's influence. However, she harbors a deep fear of graduating high school, apprehensive about navigating the sighted world. Interactions with Kohei Orihara include his attempts to understand her experience, like struggling to return library books in complete darkness—immediately revealing daily challenges.

Though Misaki generally avoids dwelling on her disability, her personal journey explores future anxieties and emphasizes reliance on strong emotional bonds for support. Her storyline culminates in Kohei prioritizing a promise to witness her graduation, underscoring his commitment.
