When Ioki and Tomisato were going out of the Nogizaka Mansion as they want to go from somewhere else together as a trip vlog but in the end, they find that the twin idol Karuki Leo is there where they were at.
Ioki: hey Nao is that Kuromi Haruka's brother doing so early in the morning
Tomisato: yes you are right that was Karuki Leo should we follow him
Ioki: I think we should follow him from behind
Both of them agree with each other and they are starting to follow Karuki Leo from behind but he didn't notice at all when he had over to the place and he notices that he has been followed by the Nogizaka46 idol member name Ioki Mao and Tomisato Nao.
Karuki: why I can feel something is not right about this
Ioki: Nao you could walk very slowly he had noticed at us
Tomisato: relax he just needs to walk faster than us
Meanwhile, Karuki and the two of them arrive at the NIS HQ building outside of the company place but he went inside and shows something to the security guard so he can go inside the lobby building.
Ioki: hey Nao could we just wait here for him to return from whatever he had to attend
Tomisato: sure we can wait here just for him
Karuki: why both of you are here following me from behind huh?
Suddenly, Ioki and Tomisato went to turn around and saw that Karuki Leo had bloodstained over his lips and same as his cheek and he had to see them in fear.
Ioki: did you kill anyone else inside there
Karuki: what...no, I didn't kill anyone inside the company
