The matriarch walked towards the closed door where Misaki entered earlier and unlocked it using the keypad. "We got everything for it on board of this ship. I shall explain how it works."
The matriarch entered the room followed by Emiko. She allowed Emiko to observe the room before she spoke again. "That is where you will take place." She pointed to one of the two pillows in the centre of the room. "One of the sisters shall sit on the other pillow and you will face eachother.
First a bowl of sake will be brought to the sister and then to you. Both of you will drink half of it, symbolising the unity of spirit. Secondly you will both use a small knife to draw blood from your thumbs, symbolising your willingness to shed blood for your sisters. And finally you will share a vial of cardamine, symbolising the unbreakable bond to the sisterhood."
