Volume 6
At Sakae Ichinose’s funeral, Makoto Narumi and Shūsaku ask Guren if the Mikado no Tsuki will be treated like this for the rest of their lives, and Guren tells them to endure it and support him for now.

Nagoya Arc
Narumi Squad pairs up with Shinoa Squad to exterminate vampire nobles in Nagoya. Sergeant Makoto Narumi introduces himself to Yūichirō Hyakuya, and Yu tricks Narumi into believing he is twenty years old.

When Shinoa's Squad faces off against Lieutenant Colonel Guren Ichinose, Colonel Mito Jūjō, and Major General Shinya Hīragi, and Guren announces their real ages after trouncing them.

Many discipline problems later, Sergeant Shinoa Hīragi apologizes for Yū.

In Fifteenth Progenitor Lucal Wesker's ward, their team waits for their mission to start. Narumi briefs the team and scolds Shinoa Squad for not coming prepared. Shūsaku keeps time before the mission. He briefs the team about their orders once again. Narumi becomes their team leader for this mission with Shinoa second-in-command. Narumi scolds Yu again for not remembering the name of their target, but Yu surprises him by listing the names of all of the members on their team.

The battle starts. When Lucal tries to attack Shihō Kimizuki from behind, Yayoi, Kagiyama, and Rika stab him from behind instead. Shūsaku takes the opportunity to bind Lucal's left arm. Unable to remove it, Lucal is forced to cut off his own arm in order to escape. They eventually succeed in exterminating him.

On the streets of Nagoya, Shinoa Squad and Narumi Squad wait for the survivors to regroup. Sergeant Aiko Aihara arrives with a bruised, battered, and bleeding face. Kimizuki notes that Aiko Aihara's squad only has seven survivors, so eight of them died. Yu offers to have his squad take watch while hers rests, and she takes him up on it. Guren and his squad come above ground, but they are all worse for the wear. Narumi reports that Shinoa Squad did very well.

Guren orders Shinoa Squad and Narumi Squad to join his squad and hunt down Thirteenth Progenitor Crowley Eusford, Seventeenth Progenitor Chess Belle, and Seventeenth Progenitor Horn Skuld and to rescue hostages. Guren orders them to stage an attack on Crowley that will last ten minutes. If they cannot kill him during that time, they will retreat and tackle the next mission with those numbers. Guren orders Aiko to hold position for thirty minutes and pass on orders to any late teams to report to Nagoya Airport. Anyone late is presumed dead.

They reach Nagoya City Hall, and after Crowley catches Gekkōin, Guren and his squad discuss what to do. After careful planning, Guren decides that his squad will take his squad to attack Crowley while Shinoa and Narumi Squads free the hostages. He gives them five minutes to rescue as many hostages as they can and act as a proper diversion for the main force in Shinjuku. As soon as the five minutes are up everyone has orders to retreat to the Nagoya Airport immediately.

Narumi Squad reappears after Kimizuki captures Yu, having already rescued the hostages. Shinoa Squad joins up with them and many injured soldiers. They flee, and Rika reports seeing a single vampire straight ahead. Shinya says they can handle one noble and orders them to keep pushing forward.

As Mika engages the Moon Demon Company, as soon as he sees Yu, he leaves his fight with Narumi, Rika and Tarō and jumps past Shūsaku and Yayoi.

Shortly after Mika flees with Yu, vampires rain down around the Moon Demon Company.

After seemingly escaping the vampires, at Nagoya Airport, a van pulls up, and Aoi Sangū steps out. Although she notices Mitsuba, she quickly turns from her. Then, Kureto Hīragi steps out.

Kureto identifies himself and congratulates them on their successful mission. He says that, thanks to their glorious sacrifices, humanity will now achieve complete victory over vampire-kind. He says he will take over now and orders them to put down their weapons and be at ease.

Shinoa orders them to hold onto their weapons and says she feels that something terrible will happen. Rika, Shūsaku, and Narumi hesitate.

Immediately afterward, he says that everyone is going to die anyway and orders the experiment to begin. Aoi launches chains from the ground at the surviving members of the Moon Demon Company. They merely scratch Shinya and fire at the other soldiers. Narumi summons his demon, Genbushin, to protect him and is narrowly able to dodge the chains. However, the chains pierce Rika through the chest and Shūsaku through the shoulder. The chains stab numerous other Moon Demon Company survivors and hang their corpses in the air.

Narumi falls to his knees, asking what just happened. Shūsaku screams at Narumi to run until a second chain pierces through his chest.
