Admin Mawile: (。・ω・。) This is a very interesting idea!!!
Shuu:
-He’s too lazy (depressed) to care much for the point system, but when he starts seeing that you’re serious about rewarding them, he might try to do a little better. While far from competitive, it’s just basic survival instinct to want to receive whatever kindness you’re freely giving to them.
Reiji:
-In his mind, this is the perfect opportunity to show his new owner that he’s worth keeping. He goes above and beyond to be flawless, and strives endless to achieve everything you ask of him. Rewards only serve to enforce that this behavior is correct, and that this is the way to get in your good graces.
Ayato:
-He also tries ridiculously hard to be on top of your chart, but more for the reason of being the best among his brothers. He’s horribly competitive, and will do nearly anything to prove that he’s the well-behaved one. Unfortunately, this doesn’t always go so well, and tends to end in clumsy mistakes.
Kanato:
-If any of the rewards are direct, non-painful attention, he can be just as competitive as Ayato. He doesn’t care about being better than his brothers, specifically, but staying in your favor is the best reward he could imagine. He also gets jealous of the others very, very easily.
Laito:
-So you’re going to play that game? Unfortunately, he only sees the attempt at offering them rewards as a way of tricking them into striving for nothing, and while he cooperates on the surface, he’s not likely to believe that you’re being honest for a long time. It just doesn’t seem like something a human would do.
Subaru:
-Well, there’s no way he’d ever be the good one. He pretty much gives up on ever being on top of the chart from the beginning, and allows himself to fall behind. However, the first time he actually earns a reward, that all changes. Suddenly, he realizes that you’re serious about thinking he can be good.
Ruki:
-As much as he’d like to be the best for his owner, he’s afraid that whoever falls behind in the point system will be punished for it. Out of a desire to protect his brothers, he ensures that he’s always the lowest on your system, so that if you have to punish one of them, it will never be anyone but him.
Kou:
-As soon as he realizes that the point system is a way to avoid being hurt all over again, he’ll do anything to be on top. He’s so scared of being hurt again that it doesn’t matter what he has to do to earn the reward, so long as it means you won’t be as cruel as the people before.
Yuuma:
-He’s also more worried about his brothers than anything, and even though he would like to earn your happiness, he’s too afraid that doing so would mean someone else getting hurt. He can’t stand that Ruki always tries to take the brunt of things, and winds up doing almost the same to protect everyone.
Azusa:
-In his mind, “reward” is often synonymous with pain. He’s delighted to be good for you and do what you want, but it might be quite the shock when you realize he thinks he was doing it all so you would hurt him. He doesn’t care if you hurt him or be kind to him, as long as you’re happy with what he does.
Carla:
-He already strives to be well-behaved, and a point system doesn’t do much to change that. For both his pride as a First Blood and simple survival when it comes to not being hurt, he’s good at being compliant and docile. A point system with actual rewards just encourages him to want to do well.
Shin:
-Even with just one other to compete against, Shin does everything to stay on top. He’s not fond of being bent to a human’s will, but the idea of being better than his brother even in this one thing means a lot to him. Unfortunately, his rebellious nature means he rarely manages to behave better than Carla.
