Kai:I've never seen her before,her energy is almost like mother's, who are you?

???:isn't it obvious? I'm your little sister.

Kai:what the?! I've never known about this.

???:Mother knew she was going to have twins,so she kept me a secret until the right time,and since we're demons,I grow up considerably fast,but your from the future though.

Kai:interesting, I wonder how father would react..

???he's still in the dark about it,but your energy is frightening though.

Kai:father and I tested to see where my power was at,I thought we were evenly matched,but I could tell he was holding back,I was as well.

???:well,how about a spar?

Kai:sure,I wouldn't mind
