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...

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.

Raizel finally faces Raskreia and the clan leaders in order to prevent Gejutel's punishment of eternal sleep and settle things down. When Raskreia faces Raizel, someone she has hated for most of her life, she decides to try to destroy him herself, but the clan leaders who serve her are unable to just stand by and watch. Only the Lord's soul weapon, Ragnarok, holds the truth about what happened in the past as the curtain rises on the battle between the Lord and the Noblesse.
