What is your MOST HATED ship and why?
I, myself, despise every Blue Exorcist Mephisto ship, as Mephisto is heartless and wouldn't fare well in a relationship, and he's mine.
I also despise Yukio x Rin because there's no way in hell that would happen. Rin just wants Yukio to be más like a brother and less distant from him, and nothing romantic. Also, Yukio is terrified of Rin and his blue flames. And Rin obviously has a thing for Shiemi.
And then SoMa from Soul Eater...they'd both argue so much. The relationship wouldn't last with how vastly different they are.
