Mikaela Hyakuya. I just don't like him. He's too bipolar, and annoys me to no end with his constant mothering of Yuu. I don't think it helped that my ex-friend used to idolize him; she asked me to start calling her Mika and she would talk about nothing except her "precious cinnamon roll". I think that just embedded a firm dislike for Mikaela in my blood.
