Level Upper Arc

 * Main article: Level Upper Arc

In the anime, she first appears in class listening to a lecture about Personal Reality. She later appears alongside Mako and Akemi, wondering about the Level Upper and why she seemingly has never heard of it before. They then run into Saten Ruiko, who has obtained the Level Upper and shares it with them. She then uses the Level Upper, allowing her to improve her abilities, but she never demonstrates her newly-heightened power. Her next appearance is in a park, watching her friends practice their newfound abilities. Akemi forgets that she was using her abilities on Muu and drops her on the ground, making Mako-chin worry about Muu. In the anime, she continues to watch her friends practice their powers when Akemi suddenly collapses, prompting her to run towards Akemi and aid her. She eventually also collapses as a result of using the Level Upper and is sent to a hospital.

She reappears in the anime alongside her friends in a special class for users of the Level Upper. Later, she joins the rest of the students in running laps around the track as part of training under Yomikawa Aiho. During Ruiko's confrontation with Elder Sister, Mako-chin is concerned about Ruiko's well-being but doesn't do anything. After Elder Sister leaves, Mako-chin commends Ruiko for not backing down and comments that she saw sparks flying between her and Elder Sister. She agrees with Akemi's statement about Ruiko saying that cheating is wrong. After the special class, she tells her friends that her statistics rose a little but is dismayed that her Level is still 0. She later joins her friends for a party to celebrate.
