When Ikoma and Mumei was revealed to be kabaneris, Ayame defended them despite the persistence of those all on board, thanking them for saving the koutetsujou. She later held a vigil for everyone when the water tank of koutetsujou was being repaired. Ayame was bewildered. when a group of worried people was sneaking in to kill Mumei and Ikoma. To prove that they are on their side, she tried to provoke Ikoma into biting her. rather than bite, Ikoma vowed that he will never run again and explained that the purpose of his life is to destroy the kabane. Seemingly convinced, the people started walking away. She later apologized to Ikoma for the incident. As she was about to leave Ikoma suddenly collapsed and tried to attack her, she was close to being bitten when Kurusu came in and stopped Ikoma. As the koutetsujou advanced due to the approaching kabanes, she was later dismissed to take control of the koutetsujou.

Under new leadership, they head for the mountain which is a faster route but more vulnerable to attacks. As they head into a tunnel, they were ambushed by kabanes and among them was a wazatori. Ayame decided to join Kurusu and the others to fight the kabanes, which confused everyone. She watched helplessly as one of her bodyguard got bitten and more kabanes kept coming. She was terrified when the wazatori came and injured Kurusu. Much to her relief she heard Ikoma promising to take down the wazatori if someone would give him blood. Determined, she cut her forearm to let her blood flow, she forms a contract between Ikoma to drink her blood in exchange that he will fight for them. Ikoma gladly accepts and as he drink the blood start to pour in his heart, which starts to beat. Exhilarated, Ikoma pinned the wazatori down and pierced its heart with his steam gun. Ayame regained control of the koutetsujou and with her in command she declares that Mumei and Ikoma will travel with them and volunteered to offer her blood along with Takumi, Kurusu and the others as well.
