( ●`▽´● ) Since this would have gotten long otherwise, I went with just the “kill anyone else” type!
Shuu:
-It’s amusing that you’re so obsessed with him, and he doesn’t really do anything to stop you. Prey that practically throws itself at his feet means that he has to do a lot less work, after all. The obsession is entirely one-sided, though, and he does nothing to get any closer to you.
Reiji:
-That kind of behavior is far from proper, and he’ll put a stop to it early. You should be firmly under his control, not striking off on your own to do whatever you please, and he wont put up with your disobedience. The killing doesn’t bother him so much as the fact that you’re acting on your own.
Ayato:
-He thinks it’s more funny than anything at first, especially if he gets to see you do something violent. He will get mildly creeped out once the behavior doesn’t stop, but so long as you make sure he feels like it’s only because you think so highly of him, there’s a good chance he’ll let it continue.
Kanato:
-While he is against the idea of you doing anything on your own, that kind of obsession is exactly the thing he’d interpret as love. Your relationship will become one that feeds off of each other, and, likely, both his and your violent tendencies will only increase as they please the other.
Laito:
-Well, killing is a vampire’s way of showing love… He’s pleased that you’re so passionate about him, and, as long as you entertain him with your actions, will encourage them. He’s likely to find ways to manipulate you even further, twisting your violent tendencies in a way that benefits him.
Subaru:
-Despite how violent he tends to be, he doesn’t like you being so vicious. It’s amusing for a little bit, but gets old quick, and he’ll try to force you to stop if you don’t take the hint. He wouldn’t have expected a human to be so violent in the first place, especially not over someone like him
Ruki:
-He doesn’t appreciate you acting on your own, especially not in a way that will cause him so much trouble, and attempts to correct the behavior as quickly as possible. He won’t tolerate you acting out, and, even though the specifics of what you’re doing don’t bother him too much, the initiative does.
Kou:
-He wouldn’t care too much, if it wasn’t for his life as an idol. If anything like that gets out, it would be bad for his career, so you can’t be allowed to do those things. He wouldn’t care about the killing other than that, though, and might even find a way to manipulate you through it.
Yuuma:
-He actually finds it pretty funny that you’re willing to go to such lengths for him, and doesn’t have any problems with your killing. As long as you’re still properly his prey, it doesn’t hurt him if you get a little violent. And anyway, your dedication to someone who’s done nothing but hurt you.
Azusa:
-As one would expect, he’s nothing but pleased that you care about him so much. The only part of what you do that really bothers him is that you could be hurting him instead. He doesn’t see any problem with you killing other people to please him, and actually takes it as a sign of affection.
Carla:
-Again, you acting on your own is the biggest problem he has with the situation. It’s not becoming of his partner for you to do such things, and he’ll be against your killing if only because it would reflect badly upon him. He’ll have a harsh punishment waiting if you do anything that displeases him, of course.
Shin:
-He actually finds the killing to be pretty amusing, and allows you to get away with it so long as you don’t cause him any problems. As violent as he is, he has little problem with you hurting people, and actually might be amused that you’re willing to go to such lengths for his sake.
