[Next day]
"Hisha, I know your used to the mansion during the day, but we are going under the mansion for forming a contract."
'Is it dark down there?'
"Pretty much but there will be a few torches light in the room."
'Then I'll be fine, I mean living in a hole underground is pretty dark.'
"Do you know what to do?"
'Yes, I have to stand in the summoning circle and recite a spell and then form a contract. I read it in an book a year ago.'
'But father?'
"What is it Hisha?"
'Do I really need to wear this dress? In the book there was nothing written about a girl needing to wear a dress.'
"Hisha I told you there will be times that you need to wear a dress, this is such an occasion."
"And don't say that you will not go, because you have to go. I can't hold this contract with Cerberus forever."
'Fine but only this once.'
"Thank you Hisha."
During their decent it was pretty dark but she felt at ease.
'This place is so nice and comfortable.'
"You know sister, most kids your age or younger are terrified when they have to go down such a place."
'Were you scared when you had to come down here?'
"I cried because I thought I was getting punished."
She started to laugh.
When they got to the room Aster light a few torches and she saw a magic circle.
Demon put her down in the middle.
She immediately started to recite the spell without a word from her father.
'You who lives in the shadow, I call for you who protects me in the dark. Hear my call and come to me, Cerberus.'
Cerberus appeared before her and she patted him.
"My Master is finally ready for her contract."
'I am, but I hope you don't turn in to a puppy, like Black.'
"That won't happen, we familiars are the size of the owns mana."
'Are you willing to stay by my side and protect me, my father and brother?'
"I am."
Hisha and Cerberus formed a contract and Cerberus was even bigger than before. She was surprised by his size.
'Uhm father… While I'm not going to complain. But Cerberus is way bigger than before, if the family see him then they know something is not right.'
"Your right, he was already pretty big. But he was living of your mana from the start so…I think it's because you formally made a contract with him."
"Cerberus can adjust his size or we can say your mana has grown because you are learning to control you massive mana."
"I rather adjust my size, this way Master can fool her enemies and they won't know how much she possesses."
She hugged and thanked Cerberus.
