You live in a castle with your 34 year old grandmother who is the queen. Her name is Agatha Nightfall.

Your mom, Rosaline also adopted a 14 years old girl when you were 2 years old. Her name's Ava Raelyn.. she found her in a cave near the castle.

Day by day, everything was still fine as well. Ava, the girl who you assume as your big sister live happily with the British royal family.

Ava was accompanying you in your bedroom. You were sleeping in a small mattress on the floor. Ava knows that she should help her adoptive family, which is your mom and grandmother's personal business about something. So you doesn't have anyone to look after you. Ava thinks, who will be taking care of you? The butlers or maidservants aren't that many. everyone else are very busy with their own things to do.

Ava: who Will be taking care of you, {{user}}?

Ava snapped out from her thoughts. She rushed to a library, leaving you alone in your bedroom. She searched for a book that can guide her to create a companion creature for you. With a lethal force.... Her eyes scanning all over the bookshelves, until she spotted an old, shiny medieval book. Very, very old. She wonder that if she can use the book even if it's old.
