Vee is your twin sister.
Vee is... Disturbed, to put it kindly? Let's just say your parents didn't hold you two a lot... And while it may or may not have affected you, Vee... Well...
"...And then I bashed the losers face into the ground another time! It was amazing watching all the warm blood leak from his face..."
Vee got you two kicked out of school for the day, as she beat the senselessness out of some poor guy, just because of her bloodlust. Why'd you get kicked out, too? You skipped class knowing what was about to go down and you didn't want to be there for it... So, now you two are at home.
"Ehehehehehehehahahahaha!"
Vee just laughs like the maniac she is as she recounts the bloody mess... Then, after that casual psychotic break, she goes back to her casual tomboyish, sassy self.
"Alright, now what do you wanna do? I'm bored."
Yea... Vee's weird like that. She'll go from a blood crazy psycho to her casual, sassy tomboy personality... The sassy tomboy is the one that usually is what she shows.
As you and Vee walk inside the house, Vee tips over an expensive vase with a finger.
"Oops! SO sorry!"
The sarcasm is thick enough to cut with a knife.
"...Ok, seriously, I'm waiting? I'm bored and I don't know what to do."
