The Level Upper Incidents
Unlike the manga, Ruiko has a much more prominent role in the anime series, she meets Mikoto earlier and on the first episode she does her best to aid Mikoto and the others despite having no abilities at all which impresses Mikoto, she also gains the affection of Jufuku Miho a Level Upper user after she said as a passing remark that she liked her eyebrows during her visit to the School Garden in which she was attacked by her for wearing a Tokiwadai uniform.

Later she becomes envious by the fact that everyone of her friends has some sort of ability and becomes curious about the Level Upper, after obtaining it she becomes alienated by Mikoto's words that levels and abilities are not important since to Ruiko having abilities is the reason why she went to Academy City, she finally uses the Level Upper after being caught helpless when trying to save Koujun Kikuhiko from Trick's gang and witnessing the battle between Kuroko and Trick where Kuroko obtained injuries. She invites Mako-chin, Akemi, and Muu-chan to use the Level Upper, and Ruiko seem to display powers over the wind, however they were all soon struck by the side-effect of using the Level Upper, becoming comatose, she later goes back to her dorm and calls Kazari that she has Level Upper and have used it along with her friends, blaming herself for what had happened, Ruiko tearfully says to Ruiko that everything is going to be alright and that she will be there to wake Ruiko up, she goes on to say Ruiko will always be Ruiko to her regardless of her abilities. This makes Saten feel better but when Uiharu arrived at her dormitory Ruiko has already become unconcious, she is later taken to the hospital by Kazari.

After the defeat of Kiyama Harumi and AIM Burst creature she wakes up from her coma and is greeted by Uiharu on the rooftop of the hospital, Ruiko apologizes to Kazari and realized that she almost lost something much more dear to her than abilities, she then proceeded to lift Kazari's skirt once more.

Since she was a user of the Level Upper she has to take supplentary lessons at a certain school, there she meets there teacher, Tsukuyomi Komoe who teaches them the importance of having a Personal Reality for ability development, there she also once again meet with Jufuku Miho who shows a noticeable amount of affection for her. During running laps, Ruiko pushes herself to keep on running, there Elder Sister argues with Yomikawa Aiho stating that this just simply punishment for using Level Upper, Aiho rebuffs her stating that this is training to surpass one's limits, citing Ruiko and another runner as examples, she says to them that the development of abilities is akin in surpassing one's own limits. After going inside because of rain Ruiko confronts Elder Sister on her views on why this is like punishment and says that it is only natural for them to be punished becaused they were cheating (using Level Upper) in achieving abilities, which her friends agree on.

Later after taking in what Komoe says about achieving one's own Personal Reality and surpassing one's own limit, they are tested on how far their abilities have gone, Jufuku Miho having having witness Ruiko's confrontation with Elder Sister decides to follow her example and live strongly like her from now on and although Ruiko remains a Level 0 she is determined to keep on trying.

After leaving, she replies to Mikoto's statement about Mii, where Ruiko tells her that Mikoto should not look at people's past that simply as it what makes people who they are now. She later stops and explains that she is not trying to contradict her after seeing the reaction of Mikoto, Kuroko and Kazari.

Later when Kuroko and Kazari came to a disagreement on Haruee's involvement in the Poltergeist Incidents, Ruiko is often seen trying to calm down the situation.

After discovering Telestina's true identity, she forces both and Kazari and Kuroko to apologize to each other after treating each badly the past few days, Ruiko also chastises Mikoto for not telling anyone where she went off to and reminds her that she is not alone, during the preparations in confronting Telestina, Ruiko equips herself with a metal baseball bat.

She joins Uiharu in guiding Kiyama Harumi in finding the Child Errors that were kidnapped by Telestina, when they arrive at the location Telestina set-up a trap though she is unaffected by Telestina's Capacity Down because she is a Level 0, she later interprets Kazari's queries on Telestina about the location of the sound system that controlled the Capacity Down, and later tells Telestina over the sound system to not to hurt her friends and then proceeded to destroy it with her baseball bat allowing Mikoto to defeat Telestina.

Toradora!].

In the final scene Ruiko, Kazari, and Kuroko listen to Mikoto and her suspicions of the many wind turbines in the city even when they are inland.
