Mits-kun, it's no use hoping that a sword will care about your feelings, or the lives of your friends. Probably, we can't be anything beyond teammates. But even if we got on a losing streak, or you got really annoying, no one I replaced you with would balance out to the amount of damage it would do to my reputation here. Not to mention that there's a good chance other teams would decide I was too dangerous and take me out similarly, or that the people you were replaced with would hear how they arrived and, again, decide I was too dangerous.
Simply put, if I thought it was worth it, I would've done it. But I decided against it weeks ago. Anyway, unlike the rest of you, I'm not in any kind of hurry.
