Meanwhile, Touma and Maru sleep in the Kobayashi room and the next morning Kobayashi was calling Maru sister and she went come to her house and while she saw that her brother was here at the Kobayashi Yui house and she hug him tightly and they didn't let go.
Touma: Maru you didn't say that you have a sister from Hinatazaka46
Maru: well she is my close
Touma: please call the operation my head is going to be hurt
Kobayashi: okay they are coming over here
While they are here and he does something on Touma but they won't get anything inside the brain because is inside the most very important thing in his brain system.
Touma: Oi what's wrong?
Doctor: sorry I can't cut it
Touma: why not?
Later Maru kills him and collects his memory and we see that he get to use by Ryo and the leader of human testing experiment in human.
Touma: he is so dead
Maru: relax sir we can kill them one by one
Mari: Oniichan did you kill someone
Maru: yes but this is the bad people is trying to kill Touma, my Friend
Mari: Oh he is your friend
Maru: yes he is and he did save my life and now they want to kill their own testing number
Kobayashi: Touma what is Maru saying?
Touma: everyone has their own number but mine is number 001
Kobayashi: so you are the first testing number
Touma nods but he can sense something ahead of this way and same as Maru also can hear they are coming here.
Maru: Mari we need to get going
Mari: why what happened?
Touma: they had found us
Kobayashi: what do we do next?
Touma holds everyone hand and Maru is holding his shoulder and Mari just hugs her brother while Kobayashi holds onto his shirt and we suddenly teleport to his old apartment building that has many traps from inside the house and outside the house as well.
Mari: where are we?
Touma: welcome to my security house that too many traps
Maru: wait did you set a trap by yourself or did someone helps you set up
Touma: no I built the trap just for myself
Kobayashi: Touma if the doctor is dead how we must do to now
Touma: we just go at them and find out
Kobayashi: no later they will kill you and I didn't want to lose you
Touma and Kobayashi go swat down and calm down together but suddenly they are here and Touma let Maru press the set trap at the outside but this house is very metal inside and but outside is too difficult to go in because Touma builds to be bulletproof and fireproof.
Touma: Maru you want to do the honour
Maru: I love too
While Maru is pressing the button and out of a sudden, the tree is hitting them hard and Touma press the button that hit the car and later the car flew into the air and explode and they can't recognize it because he is much clever than us.
Ryo: damn it why did you build them to be so smart and clever
Leader: well you ask that you want to be smart and clever
Ryo: Oh right sorry
Touma use a speak button to speak to them and later they can hear that he is breathing very weak but Ryo is shouting at him at the CCTV while the leader shooting the wrong thing and later Touma used a curse word and he was saying to him was.
Touma: you shot the wrong CCTV and here is the best thing ever bitch!!
Out of nowhere, Touma use a machine gun and fire at them and we all see all of the team are getting shot but Ryo and the leader are retreating from there and their team A and team B are dead because of the machine gun that Touma use to kill him went he was still a human back then but now he is more a superhuman.
Maru: you just kill them with a machine gun
Touma: yes but they need to be killed but I can stay here just do nothing
Maru: yes but Ryo and the leader need to get killed by your own hand
Touma: I will get my revenge on them but we can sleep here you and your sister can sleep there while I and Kobayashi can sleep here
They agree with Touma and they go to sleep and Mari text her Member saying that she is not going back to the Hinata dorm because she can stay here for a while with him.
Back at the Hinata dorm and Kumi receive a message from Mari saying that she is had a problem with her brother but she text her that she will return back to the dorm by tomorrow if she can make it in time.
Maru: what are you doing?
Mari: texting my captain of Hinatazaka46
Maru: so what did they say?
Mari: she says that can stay here with you
Maru: good for her
Later the outside of his room and we just hug each other and they start to kiss him and Touma just like Kobayashi who is caring for him but Sugai is not worried about her at all.
Touma: I'm sorry Yui
Kobayashi: about what?
Touma: about everything that happened between us?
Kobayashi: you just take care of yourself more than Maru
Touma: what if they control me and ask to kill you
Kobayashi: just fight it against your heart
Touma: okay I will try but a good night
Kobayashi: good night
In the meantime, back to the lab experiment and Ryo and the leader is finding a way to beat the testing number 001 and eliminate them in pieces but his Friend needs to see him tortured with a taser gun on his heart.
The next morning at Touma safety house security and we saw that Touma and Maru is doing something with a drone and they set up to get everything that they want them to kill each other but we see that Touma is had a sweet smile on his face.
Touma: Yui take this with you at all time
Kobayashi: wait what are you doing with that
Maru: Mari can you stay here with Kobayashi
Mari: of course Oniichan
Touma: I won't get long I promise
Later Maru close Mari eye and she didn't see what they are doing and Kobayashi kiss Touma and they break their kiss and Maru ask her to open Mari's eye and she saw that Touma has their moments together as their couple while we go there outside but skip with the set up with a lot of trap and they are already here and faces them.
