Seeing Frankenstein and Rai, Mary says that them being there means that Frankenstein is related to the children. M-21 tells both of them that the building is an old Union building, the children are inside at the lower floors and their life is in danger. In order to make sure that children and M-24 are saved, he tells Rai and Frankenstein to go down while he holds off Mary.
Mary tells him that he is a weakling who can't stop her even for a second and declares that none of them can defeat her. M-21 tries to send them away to save children and his comrade but Rai tells Frankenstein that he will go down himself, asking M-21 to show him the way. Mary tries to attack Rai and M-21 to prevent them from going down but she is blocked by Frankenstein. She tries to attack him but he easily dodges her attack and tells her that her skills are not on par with what she declared a few minutes ago.
Meanwhile, Rai and M-21 proceed to save children and M-21 notices that Rai is easily able to keep up with him and wonders if he was hiding his true strength.
