Ambition in the Demon Army

Ambition in the Demon Army is the twenty-third chapter of the manga series, Owari no Seraph.

Short Summary
Shinoa's squad meets to tell Yu about what happened on the battlefield and decide where to go from here. Shinoa's squad decides to continue following Guren. They make their official policy "Family takes care of family."

Kureto and Guren meet. Guren refuses to say what kind of technique he developed to create so many wielders of the Black Demon Weapons in such a short time. Any human capable of bearing one was experimented on at some point. As they chat, Kureto reveals his plan to first eradicate the vampires of Japan and then dominating the human survivors all across the world, making Japan the center of the world. Kureto says the vampires intend to seriously attack Tokyo in one month. He orders Guren to go on a suicide mission with 100 soldiers to Nagoya to eliminate some noble vampires while Kureto leads the main army elsewhere.

In Kyoto, Mika, Lacus, and Rene prepare for deployment to Nagoya on the same day Shinoa's squad is ordered to take Nagoya.

Long Summary
Yu wakes up. That was the first night he slept without having any nightmares since receiving Asuramaru. He meets with Kimizuki, who lives in the apartment next door, and they meet Yoichi on the way to their meeting with the girls.

Hearing screaming, the boys rush into Shinoa's room. Mitsuba added sake to the omelet she was cooking, and she now has a flaming omelet in her pan is is running back and forth across the room.

Kimizuki takes over cooking breakfast, and Shinoa begins the meeting. She tells Yu he was subjected to an experiment that made him lose control and try to kill her. She says they must decide whether Guren is only using them or if he is their ally. She states he is probably picking a fight with the higher-ups or else has a bigger plan in the works.

On the streets of Shinjuku, Guren meets with Kureto. Chained, starving vampires leap at Guren while Kureto watches. Kureto says he testing if he can force vampires to morph into demon, but these low-level vampires or worthless: most do not turn, and those that do make weapons even weaker than enchanted gear. Kureto orders them slaughtered. Guren says he followed orders to came alone because he knows Kureto will not kill him so long as he is useful.

Kureto asks how Guren created three successful black demon candidates at once. Guren says it was chance, but Kureto calls him out on his obvious lie. Every single person capable of bearing a black demon weapon has been part of a human experiment at one point, but even then the chance of successfully bearing the weapon is slim. He is happy so many bearers were created, but he requests that Guren share any more successful experiments with the army. When Kureto asks Guren if he is planning a coup, Guren answers that he is not. Kureto calls Guren weak because he cannot betray his friends or sever his emotional attachments, and he tells Guren is is unworthy of leading. He says this is why he trusts Guren. Guren asks which hostage Kureto is going to use this time, but Kureto says he was too busy rebuilding the city to bring one today.

Kureto states that anyone who sacrifices another for greed with no ambition is evil. He claims he will rebuild the the world. The first things the vampire did was to destroy all internet connections, cell towers, and other communication lines to keep human countries from getting into contact with one another. Instead of re-establishing international communication, he has a different first goal. First, he will eradicate the vampires in Japan. Then, he will crush any surviving human organizations and essentially conquer the world. Guren calls him out for acting like a kid, and Kureto says it sounds cool. He insists that Guren join him if his ambition is any less than Kureto's.

Mahiru whispers to Guren, telling him to continue following her instead.

Guren answers that he is already following Kureto, and he would be dead if he were not.

Kureto reveals that the vampires use weak and simple strategies because they underestimate humanity. Vampire enclaves do not get along or share information, and the nobility is responsible for keeping the society under control. By eliminating the nobility, the remaining vampires will fall apart. He says there are 25 vampire nobles in Japan, and he claims to know where ever single one of them is.

He sends in child spies to get the information for him, and Ferid enjoys them immensely. While Ferid down the streets of Sanguinem and checks out the cute children nearby (most of the children flee at the site of him), Dai's friend from the previous chapter approaches Ferid. He heard that letting Ferid drink his blood would get him something in return, and Ferid asks him if Mika was the one who told him that.

Kureto explains that vampires do not bother to remember the faces of humans because they are too cocky and only see humans as brainless livestock.

Kureto assigns Guren an extremely dangerous vital mission. Before the vampires bring down their army on Tokyo one month from now, Guren must launch a pre-emptive strike with a force of 100 soldiers and his three black demon wielders. He will attack Nagoya, wipe out the vampire nobles, and conquer their base. This will be a distraction for Kureto's true plan. Kureto declares he will show Guren a world where the humans make the vampires into cattle.

Back in Shinoa's apartment, Shinoa lists Guren and the Hiragi family as being the largest factions of fighting for power in the Demon Army. Yu says he wants to follow Guren since Guren saved his life. Yu says he will follow Guren even if Guren betrays him because Guren is family. Everyone agrees. Shinoa makes their official policy "family takes care of family."

In Kyoto, Mikaela, Lacus, and Rene wear their new uniforms. They have been ordered to deploy to Nagoya with the the rest of the army to eliminate humanity in the northeast. That same afternoon, Guren gives orders to take Nagoya.
