White Ghost.In a flashback, Himiko was cast out by her former friends, so she retreated to the game world and met with Ryōta, who sensed her discomfort but chose not to inquire about it. In the mainland, Tyrannos Japan discusses the game's progress noting the psychological warfare between the participants. Ryōta and Himiko take refuge in yet another abandoned building at night. Ryōta explains that he views the game world more as reality, especially with his relationship with the Himiko he knew in Btooom!, hence his reason for saving her from Masashi. Himiko silently breaks into tears, not expecting to meet Ryōta in the real world and afraid of revealing her true identity as the Himiko in the game world due to her previous traumatic experiences. Himiko wakes up at the middle of the night and screams upon the sight of a ghost. Ryōta investigates and discovers a seemingly crazed woman living nearby, knocking her out when she attacks him. Ryōta brings Himiko with him to calm down the woman, recognized as Shiki Murasaki, who was a survivor from a previous iteration of the Btooom! death game and lost trust in men. Shiki was a nurse at an understaffed hospital, working with a doctor named Masahito Date, who blamed her for his medical malpractice. As they were both chosen to participate in the death game, Masahito blasts off her left arm after obtaining six IC chips and takes her IC chip in betrayal to leave the island via helicopter. Himiko, knowing full well that her loyalty with Ryōta will be tested, returns to Ryōta, who plans to get eight IC chips as a way to hijack a helicopter to free both them as well as Kiyoshi and Shiki. As Ryōta and Himiko say goodbye to Shiki, it is revealed that Masahito was sent back to the island to treat Kiyoshi's wounds.
