Transfering characters

So far I have been playing the game on my brothers account/game as he`s second character. Since I dont live at home I want to buy the game for my self. Is it possible to transef that character to my account?

No. About the only thing you could do is transfer the armor, weapons, gold, etc from that character to a new character you create on your own account.

BTW it's against GW's EULA to share an account. So I'd advise you buy an account yourself (either online or in a box from a store), create an account and gte your brother to log in as your character on his account and transfer the stuff on there to your account and then delete your character.
