Right before Yakubo had the plan to play some games with the 5th gen only but once all of the 5th gen was in front of the TBS studio.
Sugawara: what is going on here?
Nagi: where are those doing here
Teresa: I think someone who to played a game with us
Out of the blue, Yakubo reveals themself behind the mask from the screen to save the other member inside the room.
Ogawa: what are you trying to do with them
Tamaki: she can't reply to you but once you finished the game she will tell you
Nagi: tell us what and who are you
Meanwhile, Tamaki had to introduce to them the Hinatazaka46 as the 4th gen member.
Tamaki: get ready for the game to start
Haruka: good luck guy make us proud
Ogawa: we will stop this mess that she did
Inside the TBS studio, some rooms have some clues to let the member go without getting caught by her minion.
Yakubo: did she know that I have heart disease
Tamaki: maybe no she doesn't know anything from you
Hayashi: Sakura had worried sick about you, Yakubo
The past few hours later half of the 5th-gen members finished but they returned from the living room to see Yakubo's pale skin.
Ogawa: Yakubo are you okay?
Hayashi: what it looks to you aya she is dying
Nagi: that was not possible she can't be dying right
Suddenly, Endo Sakura had come here to see the truth about Yakubo Mio's condition on herself.
Sakura: please Yakubo listen to me before you do something dangerous thing on yourself again
Yakubo: I can't do it Saku-chan I can't
Sugawara: why did you mean you can't
Without any sound coming from Yakubo's mouth later she let go of the Nogizaka member but she let herself inside the room and lock from the inside the room.
Sakura: wait...what are you doing now Yakubo!!
Yakubo: I'm sorry for you all to see me more suffer
Tamaki: you want me to company you here
Yakubo shakes her head toward Tamaki from the Hinatazaka46 4th gen member.
Haruka: why are you trying to do yourself
Kubo: you can't do it by yourself we all are here with you
Yakubo stand at the mirror screen and let them see her and they touched the screen together with Endo Sakura.
Ogawa: Yakubo senpai we all are here with you
Yakubo: thank you but a few of the members didn't know the truth about my sickness
Nagi: we let others know you are not a psycho person
Out of nowhere, Yakubo had to turn off the mirror screen in front of them who are trying to bring another member as well.
Tamaki: I will stay here with Yakubo if she needs anything
Hayashi: please stay with her side
Tamaki: of course, I will stay with her at all times
Before the Nogizaka46 idol brought some of the other members to the TBS studio went they finally are here inside the living room studio and see Tamaki standing at the door.
Hayashi: how is she doing so far Tamaki
Tamaki: we haven't even spoken to each other yet but she still hasn't moved at all
Umezawa: what is going on here?
Suddenly, Yakubo had to turn on the backlight again and see that Yakubo are about to die any second or minute later.
Sakura: Yakubo we bring them here for you to say your final last words to them
Yakubo: thanks so much Saku-chan
Nagi: why did you say the final last words to us?
Yakubo suddenly had to stop talking because she need to splat more blood than usual self but don't worry Tamaki had to inject her body with some kind of stop cough blood in her mouth everyone gets shocked by the 4th gen member to see that she becomes worse than normal we saw her truth being sickness.
Sugawara: is there something we can do to help you
Yakubo: there is one way to help me but you have to bring me Sakurazaka46 member
Sugawara: any member you say, Yakubo?
Yakubo nod weakly toward Sugawara Satsuki and she went to the Sakura studio and bring someone to help Yakubo Mio's sickness.
Sugawara: I'm sorry can you volunteer to help Yakubo sickness to help her from not dying, please
Matsuda: I go then to help her from not dying
Takemoto: you can't go because you are the captain of the member
Later Sugawara just can't decide to take each of them but the youngest member volunteers herself from getting suffer for Yakubo's life.
Yamasaki: I will go then please take with you, Sugawara
Sugawara: sure let go then Ten
Yamasaki: please call me Tenchan
Meanwhile, Sugawara brought Yamasaki to see Yakubo at the TBS studio mirror screen room with Tamaki was stand at the door.

The past months later right after Yakubo Mio had cleared her mind and she continue to stop coughing blood but she is more mature than ever before.
Sugawara: uh...Yakubo are you feeling okay?
Yakubo: I'm sorry who are you? and why did know my name?
In the meantime, Sugawara had lost her mind saying that Yakubo Mio had lost her memory of her idol career moment ever.
