While Yu attends his meeting, Guren meets with the demon Mahiru within his mind. He fairly quickly defeated Shinya in hand-to-hand and even could dominate Mikaela as a true Vampire wielding his sword while greatly empowered physically by Mahiru-no-Yo for a while using only his bare hands. Proceeding with the mission, Guren waits for his troops to arrive at the Ebina rest stop prior to leading the strike on Nagoya. He says that Yu may be able to contain the seraph by becoming a full demon. He feels relieved he left them behind because they would have been killed by the vampire. When Guren leaves, Shigure and Sayuri approach him and demand to know what he is hiding from them. During those four years, he also worked on human experimentation for the development of Shinoa informs Guren when Yu manages to overcome a Later on, Kimizuki arrives in Guren's office and asks him if he can receive a demon weapon since he is stronger than Yu, but Guren turns him down, warning him that he will be devoured by the demon if he has no bonds to pull him free from the demon's clutches. Guren compares Saitō's ability's to Ferid's.
Yu then awakens in his seraph mode. Guren arrives at Hikarigaoka Park at 1:30 a.m. the next morning, shortly before Shinya.
He tells her to shut up and drop it. He also plans to dethrone the In addition, he actually cares a lot about his subordinates and friends, considering them to be his family, both before and after the apocalypse.
Guren tells him there is no need and asks them to come play a game with him later. Shinya, Mito, Norito, and Guren leave to continue their examinations in the gym. Guren wird als ein Namanari beschrieben, ein Mensch mit zwei Seelen in einem Körper, er ist nur einen Schritt davon entfernt ein vollwertiger Dämon zu werden. He finally reaches the audiovisual room and finds Mito crying in the hands of Thousand Night soldiers. Mahiru gets up from the bed and gets dressed. Yoichi becomes possessed, and Guren orders Yu and Kimizuki to kill him. Tenri brings up how Guren deceived Seishirō in Book 1 but says it is Seishirō's fault for being deceived. Guren mentions drinking the blood of the sacrificial humans, the blood of demons, the blood of progenitors, and the seraph of the end. He calls Mahiru a beautiful monster. In Guren's condominium, Shinya is defeating Mito at shogi while Goshi and Guren watch while the 6 pm newscast reports at the scene of a fire. As Mahiru possesses him, he beheads the vampire. Ferid admits to Crowley that he was the one giving the information to humans, but he says someone even more twisted than he pulled the strings this time and points to Guren Ichinose, who lies beaten on the ground. Mahiru asks Guren if he were scared by the vampire yesterday. He also wears the uniform trousers with knee-high black boots which goes over his trouser legging. Yu counters by saying that Guren is late. Guren regains control and attacks Mahiru, stating it will not go as she plans.
They establish a rendezvous later at 5:30 p.m in apartment 501 located fifteen minutes from Ikejiri-Ohashi Station. Guren makes an expression of disgust, Kureto comments about it, and Guren says he hates torturing kids. Guren's squad takes on Once they reach Nagoya City Hall, Guren looks at the hostages being used through a telescope and knows that they are being used as bait to lure them. Guren naps while the others keep a lookout since they say it is impossible to sleep in the loud and shaking truck. She does this to emotionally hurt Sayuri and Shigure and subtly weaves illusions around them in order to tempt them with the offer of a demonic blade. He tells her he hates her, but she says she is the only one who can understand him now. Kureto grabs Shinoa by the neck, and Guren charges him. Guren does say that he is scared, and thinks that it began back when he was five years old. She and Shinya joke around, so Guren walks off. They tell each other to be careful and then split up. He dismisses Guren. She asks to speak with Shinoa. He notices there is no refrigerator, and the only things present in the kitchen are canned foods and a microwave. Shinoa comments that he is strong. Guren calls it out on being a suicide mission, but Kureto claims it is a vital mission instead. Along with that, he wears a pair of white gloves and a red standard belt. Mito struggles, but Goshi helps her understand the situation.
The demon's euphoria grows each time Guren kills people and saves his comrades.
