You're being really aggressive for no reason.

It's just like Flamelord said, that's why everyone in the RP is here.

Though honestly, the entire setup of this RP kind of puts your character in a terrible situation. Either he attacks the characters who can't touch him according to how he's written, which is most of them, or, well...

The small number of characters who would be able to harm him kill him(Saber for example could do it). At least judging by the single line of personality you gave him.
