Raizel appears in front of Raskreia and the Clan Leaders to prevent Gejutel's sentence from being carried out and put things in order. The Clan Leaders are overwhelmed by his incredible power. The real reason why the Previous Lord died is finally revealed. The battle between Lord and Noblesse begins!

As Raizel heads towards the sanctuary, his path is blocked by a powerful enemy. Meanwhile, Seira, who had been imprisoned, tries to escape to prevent Gejutel's being forced into eternal sleep. In order to protect Seira and Gejutel, Raizel and the others have to fight their own fierce battles. Can they save Seira and Gejutel?

After being summoned by Lord Raskreia, Seira headed to her hometown of Lukedonia. Raskreia finds out about the false reports to protect Raizel and decides to punish Seira and Gejutel. Meanwhile, Raizel, Frankenstein, and Regis arrive in Lukedonia to save Seira and Gejutel.

Rael appears at Ye Ran High School to pick up Seira, and attacks M-21, Takeo, and Tao. Rael, who was rejected by Seira, challenges Frankenstein to a battle. To protect his companions and to protect Raizel, Frankenstein can no longer keep silent.

Raizel and Frankenstein first met in Lukedonia, the country of nobles. Raizel took Frankenstein, who was a noble hunter at the time, into his mansion to work as his butler. Frankenstein protected him for several years, but then some among the nobility who had unfavorable opinions of the duo began to revolt. What decision did Frankenstein and Raizel reach in response to this conflict?

Since contact with Regis and Seira has been lost, Regis's grandfather, Gejutel, heads to Japan on Raskreia's orders. Once he arrives there, he unexpectedly runs into Frankenstein and Raizel. Who were the Frankenstein and Raizel that Gejutel knew in the past? Are their true identities finally about to be revealed?

Tashiro finds himself increasingly attracted to Seira, so he asks the other guys for advice. Unfortunately for him, the likes of M-21, Tao, and Takio are already a hit with the ladies, so their advice isn't very helpful, and Frankenstein only gives him boastful stories from his own history. Will Tashiro's plan to get his feelings across to Seira be successful?

Frankenstein's battle with Takio and Seira's battle with Hammer grow more intense. Tao and Takio clash as Tao tries to keep Tashiro and Kase out of the conflict, but their leader, Crans, enacts an unbelievably brutal plan in order to win... Meanwhile, Raizel reaches M-21 and uses his overwhelming power to take on Crans.

Seira realizes Regis is in danger and rushes to help him. Raizel and Frankenstein suspect that Tashiro and Kase might be in trouble as well, so they follow Seira. M-21 comes up with a plan to sacrifice himself to save all of them, and Regis confronts the danger by his side. The battle against DA-5 has begun! But they're up against the Union's state-of-the-art special forces team, an opponent that won't go down easily...

The Union's special forces team, DA-5, has captured M-21, but he sees this as a chance to search for information on his old comrades. When things don't go as he had expected with M-21, Shark begins to search for a new target... Meanwhile, Tashiro and Seira encounter Takio on the street and notice he's in trouble, and Kase is surprised to find himself hitting it off with Tao, the one he'd gotten into a hacking battle with.

M-21 finds himself suddenly blending in easily with normal life. He's even begun to develop some degree of mutual trust with Regis, even though the two of them initially clashed over every little thing. Tao tries to hack into the police department's security system, but Kase intercepts him, and an unexpected hacking war breaks out. Meanwhile, the Union's special forces team, DA-5, finally tracks down M-21's location...

Two nobles, Regis and Seira, arrive at Ye Ran High School as part of their investigation into a series of incidents in Japan. Raizel and Frankenstein conceal their identities when they interact with the duo, but Regis and Seira realize that M-21 is a modified human and grow wary of him. Meanwhile, Tashiro is caught up in another fight with street punks on his way home from school...

Raizel, protector of the nobles, along with his loyal butler Frankenstein and former Union experiment M-21, continue to spend their days at Ye Ran High School while keeping their true identities secret. They were living their lives as normal until one day, when a violent gang barges onto the school grounds. M-21 is forced to make a choice in order to protect the students. Meanwhile, DA-5, a mysterious special forces team, is dispatched to Japan on an investigative mission. What will become of the trio's peaceful new life?
