He is found by Tobio, who was searching for him along with Natsume and Lavinia. As Tobio follows him, he asks Tobio the reason for his presence, to which Tobio replies that he's trying to rescue their former classmates from the Utsusemi Agency. They introduce themselves to each other and make their way to the fifth floor, where they are confronted by Kazuhisa who overwhelms and subdues the both of them with a powerful clay doll. Kazuhisa tries to kill one of Tobio's friends in a, particularly cruel manner, making Kouki express rage. Kouki then watches one as Tobio's power increases and forces Kazuhisa back. They are subsequently joined by Natsume and Lavinia, and decide to make their way to the meeting with the Governor General. At the meeting, the Governor-General further explains the current situation to them and also their Sacred Gears.
Later on, the team decides to visit the house of Sae in relation to the current situation. Upon their arrival there, they split into groups of two with Kouki being with Natsume. Soon after, they find out that they have been ambushed by the enemy, with Tobio telling him and Natsume to escape. As they run away from the premises and reach a deserted factory, Kouki is confronted by an Utsusemi taking the form of his close friend's little sister. Letting his guard down, he is impaled and suffers a serious injury. Kazuhisa reveals himself as the instigator of the incident, appearing with Kouki's friend. His Sacred Gear, Byakusa, performs medical treatment on him. As the situation looks bleak, he tells Natsume to escape but their Sacred Gears suddenly evolve and defeat Kazuhisa, who tries to escape, only to be obstructed by Vali. As Vali attempts to handle Kazuhisa, Kouki tells him to wait and punches Kazuhisa himself, collapsing afterward due to his injury. He is subsequently teleported by Vali to the Grigori institute along with Byakusa.

As they rest at a park downtown, they are suddenly joined by a bespectacled young man who introduces himself as Seiryu Kushihashi. Quizzed on his intentions, Seiryu replies in a vague manner, making Kouki irritated as he summons Byakusa. He fights against Seiryu along with Tobio, but the match is interrupted by the arrival of Barakiel, Vali, and Suzaku Himejima, who asks for a meeting.
At the meeting, Suzaku apologizes for the incident with the Utsusemi Agency and informs them that they are searching for their former classmates, who are being chased by the Utsusemi Agency and the Wizards of Oz. She then asks for an alliance, much to the surprise of himself and some others. They agree to the alliance, resolving to rescue their former classmates. As they prepare and head towards the location, Barakiel warns them about the abilities of their potential enemies and Lavinia tells the team about her past, leading them to express their support for her. As they reach closer to the location, Sae raises an alarm, causing Barakiel to investigate ahead. He finds Shigune Nanadaru, one of their classmates, along with her Sacred Gear. She warns them to escape, just as they are confronted by a strange stone statue. Soon after Barakiel cautious the team to close their eyes, the statue releases an intense light that is revealed to be capable of causing blindness. A man soon reveals himself, expressing his desire to make them blind. Kouki attacks the statue along with Tobio, as the man is forced to retreat. Shigune then tells them that Koga, their other classmate, is fighting alone in the village.
Following that, they head towards the village. After they feel a powerful aura determined to be that of Satanael, Barakiel decides to pursue Satanael alone and gives instructions to the team. After they reach the location, they discover Koga who is surrounded by gruesome corpses, which disgusts the team. Koga acknowledges Kouki and the rest of the Ryoukou students. They notice Augusta and several other magicians, who have surrounded them. As Lavinia pursues Augusta alone with the approval of the Ryoukou students, Kouki tells Tobio, Sae, Natsume and Shigune to follow Lavinia while he deals with the other magicians along with Vali and Koga.
Later, Kouki and others are informed that Augusta managed to possess Lavinia's body. They receive instructions from Azazel on how to combat Augusta. Kouki then helps the rest of the team to defeat Augusta and safely retrieve Lavinia. Ten days later, the team is shown together in a hospital as they express their support for Lavinia in her future goal.
