Inside a big room of the castle.
A boy along with two girls. One was about the same age as the boy while the other was a little older than him.
There were also two ladies with them. Both of them were looking like sisters but they were mother and daughter.
The people in the room were none other than Eren, Lucy, Lilin, Lumila, and Aarim. They were getting ready for the contract.
Lilin came forward and made a small cut on her hand so that blood can come out. She also stopped her regeneration and recovery power of that finger so the wound doesn't heal.
She made a circle in the ground with her blood and told Eren and Lumila to stand in the center of it.
After completing the circle, Eren wounded himself to get a little drip of blood and poured it into the blood Lilin.
Aarim then came forward and canted about something that Lucy and Lumila didn't understand. But, Eren understood it clearly.
