Anzu Hoshino, a first-year high school student, is characterized by her pronounced aversion to real-life romance, prioritizing video games, chocolate, and her pet cat Momohiki. This focus is disrupted when the magical entity Riri confiscates these three cherished possessions, compelling her into romantic scenarios designed to counter Japan's declining birth rate by matching her with partners. She possesses red hair, red eyes, a medium height, and a slim build. Her typical attire features casual clothing, often adorned with cat motifs, later evolving towards more conventional outfits and occasional makeup under Tsukasa Kazuki's influence. Her school uniform consists of a white collared shirt, a dark blue plaid skirt, knee-length socks, and red-and-white sneakers. Anzu's personality blends logical thinking, blunt honesty, and a deeply caring nature. She remains indifferent to strangers' opinions yet adheres strictly to her moral principles. Initially resistant to forming connections, she gradually cultivates genuine friendships. She demonstrates significant courage, confronting Yukana Kishi (Tsukasa's stalker) despite sustaining injuries, standing against Tsukasa's victim-blaming father, defending friend Saki from false accusations, and supporting Hijiri Koganei's development into a more empathetic person. Her journey transitions from actively avoiding Riri's orchestrated romantic entanglements to forging authentic bonds with the "romantic candidates." She becomes instrumental in their personal growth: inspiring Tsukasa to regain confidence, motivating Junta Hayami to pursue baseball, and encouraging Hijiri towards self-reliance. Her relationship with Riri evolves from antagonism—frequently expressed through physical comedy—to mutual reliance, culminating in her exploiting a loophole to keep Riri by her side after their replacement by another wizard, Kate. Key relationships include Tsukasa Kazuki, whose trauma from stalking she helps alleviate; childhood friend Junta Hayami, whose genuine feelings she acknowledges but tactfully avoids; Hijiri Koganei, whose initial arrogance she challenges; and Riri, whom she eventually considers a companion despite their contentious dynamic. Trivia notes detail her intense fear of insects (especially cockroaches), a July 11 birthday, a height of 5'6", and blood type O. She is designated an "anti-heroine" for rejecting traditional romantic tropes. Her name means "apricot" (杏子), with her surname translating to "star field" (星野). Anzu Hoshino's story will be portrayed in an upcoming live-action film adaptation scheduled for release in December 2025, though specific deviations from the source material remain unspecified.
