Shark and Hammer go out to kill time by trying to find the kids Takeo met previously. They easily find them and even discover that the kids Takeo and Tao met coincidentally know each other. Regis, who is with the children, senses an aura full of bloodlust and looks around. Seeing Shark and Hammer, he confronts the modified humans.
Regis, Shark and Hammer go to a place where Hammer sets up his equipment so people will fall asleep if they get near. Shark tells Regis that he is glad to meet the boy again since their previous fight was interrupted by Kranz. He belittles the nobles like before but one simple remark from Regis makes him enraged and he attacks first. Shark points his knife toward Regis while approaching the young noble but Regis easily deflects his attack and disarms Shark. Now, Regis belittles Shark.
Shark tells Hammer not to interfere and claims Regis as his target. He tries to stab him multiple times but Regis avoids all the attacks. Regis starts attacking while using mind control which surprises Shark when his body freezes for a moment. Shark barely avoids the attack but realizes that he cannot move again. Regis attacks again and slashes Shark on the chest, twice. It suddenly dawns on Shark that the kid could be using Mind Control. Regis tells Shark that his mind control doesn't work perfectly but is enough to dispose the likes of him as he strikes to kill Shark.
Before his attack touches, however, Hammer kicks Regis away. Shark chides Hammer in anger (for interfering) but Hammer simply states that Shark isn't in a situation where he can be picky. Regis skids to a stop and starts to attack again but Hammer throws little explosives towards him. Regis escapes the explosion and approaches Hammer from the back. Hammer notices the kid but before he can make a move, Regis uses mind control on him. He realizes that this is what happened to Shark and it is too late to evade the noble's attack. This time, Shark interferes and saves Hammer.
Shark finds it incredulous that they are losing to a kid but Hammer tells Shark that they should retreat.
Hammer convinces Shark that they can't risk danger for something not important to their mission. He tells Shark that if he wants to fight, he can fight alone. Regis tells them that they can run away, he will not stop them because he believes that it is undignified to fight foes that are running away, and then he himself leaves.
Shark and Hammer return to the DA-5 hideout with Shark quite annoyed to be humiliated by Regis. Kranz asks them what happened and Hammer simply states that they were beaten. Kranz commands them to report and they explain what happened.
Regis comes home and tells Seira that the people "from last time" challenged him again. Frankenstein inquires about the "from last time" part and Regis tells him that they were M-21's colleagues. Frankenstein asks whether he saw M-21 but Regis replies in the negative, saying that he only saw those who took him away.
