Anything Random~: -Info-Characters in my Pre-done Story

Well,i think i need to make one 'short' story by myself.
I already write the characters name and her/his personality.
The main characters :
1.Sienna Cross,13
Our main character!Her life are good and straight,before she know she's a half vampire and she meets Lilac.She's really kind and soft when she's on Human Mode.But,if she's on Vampire Mode,she'll kill all creatures she see.Learn spells from a vampric (in some place vampire-witch),Jenna Moonlight.
2.May Cross (Maie viel Chiou),34
May's name means : May,vial of Blood.The most bloody character in my story.She's jealous of humans,because they're (it's her thoughts) the most perfect creature in the world.She's so cold.But,if one of her seperated sister hurt by anyone,she can kill them who hurt her sisters instanly.
3.Lilac Cross (Lielac de Verucrosse),???
Head of Cross Family.She's kinda nice,but if she meet a human,she'll kill them,when or where she is on.The most old character in my story.She already life at Rome era (it's...about 1000+ before century).
The other characters :
1.Kyla Cross (Kaiyle loc Berrumaoth.It means in my dictonary : Kyla on a pool of Vermouth).Lilac niece
