2B anime when?
Not really, most of them have lots of issues and would kill you just because.
You have a transgender once a king that is delusional with erasing herself from history.
The cliché tsundere that's obsessed with money and will kill you or erase your memory because that's "the magus way".
There's the worm slut that will act all nice and then plunge you into a hell of her own making. Also she's high maintenance as she needs sex all the time which may or not be a con.
Then Kara no Kyoukai gives you the almost serial killer that is rough and bland.
And most of the other servants are a bunch of clichés and not important enough to remember.
