This chapter opens with a description of the battle between the two lesser cluster ships. The lesser cluster ship has entered the center of the great core of the sidonia, while the larger cluster ship is in the process of attacking it. The smaller ship is preparing to fire a cannon at the larger ship, but the cannon will not be able to stop the attack. If the smaller ship does not fire the cannon, it will be destroyed. Tsumugi is still alive, but she has lost a lot of her own body tissue. She says that she will fix her up just as she was before. The captain of the smaller cluster ship asks the captain if he is in command of the greater cluster. The man replies that he is. He says that he has been acting as the captain's proxy since the beginning of the meeting. He asks if there is anything he can do to help the captain. The ship raises its emergency level to ten.
