Raphael!
To be honest the main reason he comes in #7 is because of fighting style, it's very easy to use and can pack quite a punch, although he does have servants that follow his every whim which is kinda cool. So really isn't much to say I don't like his personality(he acts like the stereotipical rich snob) but his fighting style and possessions make up for up.
