Background

Utaha is a renowned second-year student whose beauty makes her one of the school's celebrities. She first encounters Fushimi Makoto outside a bookstore while speaking with Matsukaze Mayu, who recognizes their shared interest in stories and introduces them. Utaha is immediately intrigued upon learning that Makoto writes fiction and asks to read his work the following day. 1 8 9

After reading Makoto's story, Utaha praises its ending as “hair-raising” and brilliant. Their discussion of adapting it into a novel or screenplay establishes their connection, and Utaha accepts Makoto as a friend despite acknowledging that she is not especially skilled at maintaining interpersonal relationships. 11 12

Utaha later writes a new novel whose male lead is based on Makoto. Her drive to improve—both creatively and personally—becomes closely tied to her growing interest in him and her rivalry with Yukino Yukinoshita. 48 212

Appearance

Utaha is a tall, curvaceous girl with long, straight black hair, red eyes, and a mature silhouette. Her most recognizable style is her school uniform paired with black stockings. 8 97

  • Tall, slender frame with pronounced curves.
  • Long black hair, usually worn loose.
  • Red eyes.
  • Frequently wears black stockings, which become a defining part of her public image and personal style. 8 97 241

Personality

Utaha is intelligent, proud, and highly proactive. She openly pursues opportunities that interest her, whether that means approaching Makoto, seeking information about his other relationships, or inserting herself into a production project. She is capable of subtle social maneuvering, but her plans often fail when Makoto or Yukino sees through them first. 21 22 268

Her strongest trait is her competitiveness. Utaha treats Yukino as both a benchmark and a rival, refusing to accept being left behind in writing, filmmaking, observation, or physical ability. Even after losing a contest or confrontation, she redirects her frustration into a promise to improve. 220 221 229 269

Utaha also has an intense creative temperament. Once inspiration takes hold, she can become completely absorbed in writing, producing days' worth of work in a single evening and struggling to stop until her ideas are exhausted. 97 98 418

Meeting Makoto and Pursuing Writing

Creative Breakthrough

While visiting Makoto's home to discuss writing, Utaha is affected by Yumiko's Queen Aura and enters a state of intense inspiration.
