In the meantime, at the Nogizaka Mansion, there has someone who was looking for his sister who is here at the Mansion and it was Takashi Yuri and he had come back from around the world travel but he miss most of his sister Yumiki Nao so much.
Takashi: I'm glad that I come back to see you back on track Nao
Yumiki: Takashi nii-chan you are back from travelling the world
Takashi: yes I did but now I want to spend time alone with you my sweet sister
Right before Yumiki and Takashi were talking to each other and others can see that we have a special guest who was here to see Yumiki Nao back home to have sweet family time with him.
Legacy: what we have here...
Kaki: senpai do you know him?
Legacy: yes of course I know him and he was my high school friend and even in college days
When Takashi have seeing Legacy had to wawalknside the Nogizaka mansion and he goes after him and dodoetheirir old handshake that we have done back in school where we stwerstudentnt life.
Legacy: Takashi...you were back here to see your sister right?
Takashi: yes I am but can you explain to me what did happen to you and why did you have some metahuman power
Legacy: oh that was a bit hard to explain to you but I can show you if you wish to see
Takashi dragged LegLegacy'snd and later Yumiki also followed them to the basement floor where they had built the secret superhero lab just only who had a new power to control his power.
Takashi: where the hell are we?
Nakamura: welcome to the superhero lab underground the Nogizaka mansion
Takashi: wait...I know you and you are Nakamura Reno, right?
All of the 3rd gen members of Nogizaka Mansion had to see that the 4th gen member had a most gentle brother who had come here to just see Yumiki Nao and he had so much muscle in his body like a bodybuilder.
Iwamoto: Yumiki you didn't tell us that you have a brother who looks like you but is different in the height
Yumiki: yea he had the same face but he also joined a model career
Takashi: well I am very honour for you to say that to your member Nao
Back at the Sakura studio, Onuma was trying to control her power to finish what Legacy had to do with her practice to control her new metahuman power inside of her body.
Onuma: man...it is so hard to control my power
Rena: hey...Onuma are you okay?
Onuma: yea I am fine but can you give me some water for me to drink I need to continue the rest of all the work done
While Rena was giving Onuma some plain water for her to drink and another of the Sakurazaka46 idol had seen them working as a group team but she was half done with her power to control the power of metahuman.
Legacy: so what did you do here, Takashi?
Takashi: just want to rest for a few days but I need to talk to someone but not my sister
Legacy: sure you can talk in private with Seimiya Rei
Out of the blue, Seimiya had to see that Yumiki Nao's brother want to talk to me about something important mess on someone who want to take some action against them.
Seimiya: do you want to talk to me?
Takashi: yes and please come with me outside the mansion
Seimiya: sure and Yumiki I borrow your brother for a while okay
Yumiki agree with Seimiya and they went outside the mansion and talked with each other went had walked away from the Nogizaka mansion and started to speak to Seimiya.
Takashi: Seimiya...can I trust you on this
Seimiya: yes I can trust you and Legacy trust you as well right
Takashi: I have something for you to read and I have someone give me a letter just for me but I'm scared to read it
Seimiya was taking a letter from Takashi and she open the resolve and she started to read the letter from someone who had given him.
To: Takashi Yuri
I have an important to ask you about your condition and health that you take from yourself there has some a bitwarningsning that you shouldn't take but you take them and inject them inside your body.
P.S: it will kill you or worse you could have died in vain
From: Nanba
Once Seimiya has done reading the letter from Nanba and her face looks to become more worried about his condition health but he was Yumiki Nao's sister and I can't tell her about this not yet or maybe she will find out soon enough.
Seimiya: wait...you did what to yourself!!
Takashi: I did it to myself for saving Yumiki Nao's life nothing more
Nakamura: Seimiya what are you holding there in your hand
Legacy was taking Takashi's warning letter from him and he start to look like he had to scold him not to take that long without permission from someone important to him.
Yumiki: Takashi nii-chan what it says?
Legacy: come on tell your sister the truth if not you going to leave her behind ever again
Takashi: I'm sorry Nao I had to inject something inside my body for you to be safe everyone was here with you
Suddenly, without any warning, Takashi felt something heavy inside his chest and he was kneeling on the ground while Yumiki was calling his name a million times toward him.
Yumiki: nii-chan...are you okay?
Legacy: Takashi hurt you from inject yourself against someone for you to protect her
Takashi: Nakamura...can you take that and give me some
Before Nakamura Reno was taking some of that and she give it to Takashi and he was wrapped around his hips he touched Yumiki's cheek and he had to say his sweet and cool goodbye to her.
Takashi: Yumiki...please take good care of yourself and please listen to Seimiya Rei *flew into the sky*
Yumiki: wait...nii-chan where are you gogoinglease do not kill yourself again nii-chan!!
Seimiya: it looks like Takashi is going to save us all
A few months later Yumiki Nao had been not with everyone in the living room but she stayed inside the dorm by herself and she never eat or drink or even talk with the other members as well.
Legacy: how is she doing so far, Seimiya?
Seimiya: she doesn't come out from the dorm or even talk to us
Nanba: I'm sorry where is Yumiki Nao?
Without any sound coming from both of them and they can see that we have some guests from the Sakurazaka46 idol member who was here to visit Yumiki Nao.
Legacy: Nanba what are you doing here with Rei?
Rei: nii-chan wants to see Yumiki Nao in person to have to say to her something
Nanba: can I see her in person, please
Legacy was moved aside for him to go upstairs to see Yumiki Nao and have a talk with her about her brother who had gone missing or had died in space.
Nanba: Yumiki Nao please open the door
Yumiki: please leave me alone I won't talk to anyone but just my brother and I miss him so much
Nanba: I came here to tell you that Takashi Yuri is alive and I need you to come with me
Out of nowhere, Yumiki Nao had to open the door and she hugged him and she have some tears in her eye and we can see that Yumiki had come out of the dorm room with Nanba.
Legacy: did you say that Yumiki's brother is alive from somewhere else
Nanba: yes I did but we can summon him here inside the Nogizaka mansion
Legacy: how can we do that here
In the meantime, Nanba was holding onto Rei's shoulder and she was holding onto his hand while he was doing some spell around the Nogizaka mansion sofa without any sound coming from Nanba and we can see that he had summoned back Takashi's body from frozen in space.
Yumiki: wait it is Takashi nii-chan?
Legacy: let me un frozen his body
Yumiki: please do so
When Legacy had to take himself to do some kind of full max power onto Takashi's body he had frozen in space with some other help from Kaki and Nagi was beside him the whole time.
Kaki: senpai please focus on me with Nagi
Nagi: yes nii-chan please focus and you can do it
Legacy: thank you both of you
Meanwhile, Legacy is doing some focus spell on Takashi and he is working well enough to bring back him to the world that he loves the most of all time with his sister Yumiki Nao.
Takashi: where am I here again?
Yumiki: nii-chan...I'm glad you are back here save and what are you thinking
Takashi: I'm sorry Nao but you could forgive me back
Yumiki just hugs him with Seimiya who had a bit of a crush on him and they are happy again with someone who had been doing some mistakes about some stupid thing to do with their family member.
