Right before Kaki and other are going back to the Nogizaka Mansion but Tomita had informed that Legacy need to attend the Nogizaka Academy with Kaki Haruka but he has to wear some Nogikoi school uniform for boys and girls.
Tomita: sir you have to attend the Nogizaka Academy together with Kaki
Legacy: argh...fine let go Kaki and Nagi wait for me here
Nagi: sure nii-chan I will and Kaki please make sure you stick with him
Kaki Haruka nodded at Nagi and later we had to go to the Nogizaka Academy for something job important to have some backup to do here.
Kaki: senpai what are we supposed to do here?
Legacy: Tomita give us a mission for us to do here
Kaki: what did she give you?
Once Kaki and Legacy arrived at the Nogizaka Academy and they can see that something is completely wrong in place in the different timelines.
Legacy: well it is a different timeline of are were present day
Kaki: senpai meaning is what?
Legacy: meaning we are struck inside the past timeline and don't worry we can escape from here
Back inside at the Nogizaka Mansion inside the superhero lab on the basement floor together with Team Hinata and they had lost the single of being trapped inside at the past timeline of Nogizaka Academy.
Tomita: Haruyo anything from Legacy or Kaki?
Haruyo: sorry we can't reach them
Kanemura: what can we do now?
Back to the past timeline at the Nogizaka Academy and they went inside to check the school out before their time run out we walked inside the school and suddenly, Legacy had to stop while Kaki bumped into his back.
Kaki: senpai what's wrong did you see something suspicious over there
Legacy: yes I have but it coming from inside the classroom should we go and check out
Kaki: senpai I'm scared what if a thing comes out from there
Legacy was holding onto Kaki's hand and we had to go inside the classroom and see what is going on and why did have some light inside the classroom.
Legacy: what the hell it is?
Kaki: senpai...why he looked like you?
Legacy: I just want to touch it if was myself
Later Legacy was touching himself on his shoulder and suddenly, Legacy had some kind of bad feeling coming right this way to them.
Legacy: Kaki please hug there something is coming inside the classroom
Kaki: okay...senpai
Legacy: Kaki please embrace yourself
Out of the blue, there have some black figures who are here to protect the timeline from the past and they will ask him to leave this place or help themselves into the real present-day somewhere they are from.
Legacy: Kaki...please don't open your eye while I say so
Kaki: okay senpai
Legacy: damn it please I just want to save this timeline from the past
Without any sound coming from both Kaki or Legacy went they teleported back from the present day inside the machine where Tomita and Kanemura were trying to reach them.
Legacy: did we back in the present day?
Tomita: sorry sir it is all my fault that you and Kaki need to go back in the timeline from the past self
Nagi: nii-chan...are you okay or did you hurt yourself again?
Legacy was letting go of Kaki and she now can open her eye and see that we are back to the present day inside at the Nogizaka Mansion with everyone here seeing them back alive.
Legacy: Tomita...please see me after this
Tomita: sure I'm sorry sir
Legacy: next time you need to recall what you did early today
Tomita Suzuka was waiting for him to finish whatever his sister need to do with his injured staff on his arm shoulder while he had done with that he went to meet Tomita Suzuka outside the basement floor and went into the living room.
Tomita: did you want to see me, sir?
Legacy: yes come here I want to ask you something
Tomita: what did you want to ask?
Legacy was take out Tomita's upgrade badge to give her vice-captain of the team Hinata followed by Haruyo and Kanemura with Onuma and they were happy that Tomita had been promoted to vice-captain.
Tomita: sir what did you give me a vice-captain badge?
Legacy: well that is a test from Onuma and others who here who with the plan give you a vice captain badge
Tomita: wait...Haruyo and Kanemura you know these whole time, have you?
Haruyo and Kanemura was nod at her head toward Tomita who are been confused the whole time Legacy had to go inside the lab on the basement floor and go inside the tube room to recharge himself because he have to recharge 100 % of his battery to be used inside his body.
Nagi: Kaki...did you see my brother?
Kaki: yes I saw him on the basement floor inside the recharge tube
Nagi: okay thanks
Once Nagi went there to see that Legacy's body is lit up with some purple light on his skin with some line flow to his body while he was recharging himself inside the tube room.
Nagi: nii-chan...can I come inside the company you
Legacy: sure why not Nagi I need some to make me relax
Nagi: okay nii-chan
Before the evening passed by so soon and later team Hinata returned to the basement floor lab and they see that we have Inoue Nagi and Legacy ping inside the recharge tube just for superhero only but he need someone to company him and sleep next to him.
Haruyo: aww...how cute are they sleeping together
Kanemura: Haruyo...could you lower your voice they are trying to sleep
Haruyo: sorry...*whisper*
In the meantime, back at the Sakura studio where Onuma had a weird feeling about their couple relationship between Rena and Onuma but someone was there to tell a few about their real couple inside the studio it was the new gen member and her name was Yamashita.
