Yumi Suzune

Yuna's older brother, who is a cross dresser being mistaken ironically to be a girl. He really hates liars, saying he would tear out Kenji's throat if he broke their engagement, which is why he has a yandere personality. Though it is unknown if he is gay or just enjoys acting like a girl. Though he looks very girly, he is actually much stronger than Yuna. He is still currently Kenji's fiance with a wedding ring on his finger, however later calls it off stating he was just teasing, and he hates the student council president because he calls him male even though he calls himself female. He was the Student Council President, but after he started to give attention to Tadashi, both Saya and Saki spoke against it. He renounces the position after figuring out that his sister has a crush on the Student Council President, believing that would be more enjoyable to exploit. In chapter 50 it is revealed he has been living with Kenji after forcing him to marry him, but only using that position to boss him around and use him as a chair. He then divorces him so he could marry the Student Council President (where throughout the entire time the Student Council President was completely unaware of what was happening) as a way to get his sister to dress more girly like when they were younger. He later forces Kenji to remarry him.
