Sagiri's mother was the mother of Izumi Sagiri and the second wife of Izumi Kotetsu. Through her marriage, she became the stepmother of Izumi Masamune. Her full name has not been revealed. Like Sagiri, she has long silver hair that she ties into a long braid with a pink ribbon and draped over her left shoulder. She also has blue eyes. She is shown usually wearing a pink sweater over a purple one piece dress and a necklace with a mini pink ribbon on it. She is shown to be a caring mother, showing concern when Sagiri refuses to go to elementary school and making sure to comfort her after she caught a cold. She also praised her daughter for her drawing skills, even offering to teach her. Like Sagiri, she has a perverted side and particularly enjoys drawing erotic images, even becoming excited as she draws a pair of panties before Sagiri interrupts her and asks her to teach her to draw. She is also a bit surprised when Sagiri points out that she learned her panty fetish from her.
Eromanga-sensei
Masamune Izumi is a light novel author in high school. His artist, known only as "Eromanga Sensei" is reliable but Masamune has never met him and assumes he's just a perverted otaku. Masamune's little sister is Sagiri, a shut-in girl who hasn't left her room for an entire year. She even forces her brother to make and bring her meals when she stomps the floor. Masamune wants his sister to leave her room, because the two of them are each other's only family. One day Masamune discovers that Eromanga Sensei and Sagiri are one in the same. Further chaos erupts between the siblings when a beautiful, female, best-selling shoujo manga creator becomes their rival.
