Mutta is assigned as Vincent Bold's backup for the next lunar mission, cementing him on a journey to the Moon. He is very tired on his first day, having stayed up late the previous night researching Hibito's disorder after their conversation. Kenji and Nitta, meanwhile, are assigned to zero-gravity training. While they are not yet given any details of a mission, Chief Butler assures them that they will understand why once assigned to a mission. Lowry and Dr. Olivia prep Hibito for his test to go back to active duty.
