In Episode 140 it was revealed that Kourin had become Reversed during a fight with Aichi. But during the fight she found herself unable to ride her "new ace" as she did not want to harm Aichi and respected him too much. As a result she ran into the forest. She is soon seen returning to Miyaji Academy with the Student Council Secretary stating that she will not hesitate any more and proceeds to fight Kamui revealing her new ace Broken Heart Jewel Knight, Ashlei "Reverse" as well as her new Quintet Wall Sentinel which managed to save her and claim her victory in the end thus Reversing Kamui just as Aichi and the others had just gotten back.
