Tsubasa Nanase/Relationships

Kiyotaka Ayanokōji
Tsubasa seems to hold an interest in Kiyotaka ever since she was first shown in the series as she frequently looks at him as if she was trying to learn who he was. While Tsubasa keeps her polite facade around everyone she sometimes slips when she is talking with Kiyotaka and reveals her true feelings without realizing it. At the end of Volume 1 after Housen had stabbed Kiyotaka she looked at him with eyes of hatred and admitted that she helped Housen because she believed he didn't belong in this school.

In Year 2 Volume 2 her polite attitude returns when she talks with Kiyotaka again but before she left she told him to make sure not to leave any regrets in his time left in school with a strong determination in her eyes.

Suzune Horikita
Tsubasa and Suzune seem to have a cooperative relationship in Year 2 Volume 1 as they both understood that they need to work together in order to have both Year 2 and Year 1 D Classes cooperate and survive the Special Exam with no dropouts. They helped each other through most of the volume until it was revealed that while Tsubasa did want the cooperation of classes her and Housen's main goal was to expel Kiyotaka which caused Suzune to be more suspicious of her afterwards.
