Izumi, Sagiri

和泉紗霧

Sagiri learned to draw from her mother at a young age, and by the time she was about nine, she had become Masamune's illustrator. A year prior to the novel's events, Sagiri met Masamune, although she failed to recognize him as the author she was collaborating with, despite their similar names. Following her mother's death, she temporarily ceased drawing and leaving her room. After watching a live video of someone drawing and receiving feedback, Sagiri developed an interest in live streams. She began drawing on camera while concealing her face and voice to prevent anyone from recognizing her or discovering her identity. She eventually began interacting with viewers of her stream (while remaining disguised). At one point, Masamune was too occupied to cook, and she chose to go hungry rather than leave her room to obtain food.
