After Gentaro reveals his identity as Kamen Rider Fourze to her, she reveals that she had known the fact that he is a Kamen Rider all along and attempts to convince him to quit by stealing the Fourze Driver, but she is persuaded afterwards by both Gentaro and Yuki to return the Driver, when the Libra Zodiarts attacks the last altar keeping The Hole above Kyoto from collapsing.

breaks down when Sugiura disregards her loyalty all these while altogether and chooses to punish her for her inability to capture Tomoko instead. She indirectly help to bring an end to all the madness happening in the school by telling Gentaro all she knows about Sugiura and Sayaka.
