Right before Kanemura and Shiba were fighting each other with her brother who are behaving like any cold blood person against them.
Shiba: it looks like you going to have to kill me
Kanemura: I won't hurt you, Nissan
Shiba: I'm sure you do Kanemura
Out of the blue, Kanemura wants to use half of her power against him but Morita blocks her move to save Shiba's life.
Shiba: move out of the way, Morita!
Morita: S...Senpai...?
Kanemura: Morita please let me handle him
Before Shiba used Leo and Prince's power to destroy his sister's power and Leo Prince getting tired Shiba just dried their power away.
Leo: Shiba please stop and do this
Prince: yes and snap out from
Shiba: both of you shut up!! *full power*
In the meantime, Kanemura had shielded others except for Karin and she had half burned her leg along with her arm.
Karin: ah!! my both leg and arm half burn
Shiba: Kanemura you can't do anything to them
Kanemura: Nissan!!
Tamura: all of us need to do something to bring back his sense
Suddenly, Shiba stops using his full power and drops his sword on the floor in the simulator room.
Kanemura: Nissan...!!
Leo: wait...don't move just yet Kanemura
Kanemura: what's wrong now, Leo?
Shiba slowly looks up at them with his dark past self as the new villain who is taking control of his body.
Shiba: you all can't defeat me
Kanemura: please stop this Nissan
Shiba: I am the darkness who had living inside Shiba's body
Meanwhile, Shiba was walking away from them but Karin had stabbed the sword at his back but he didn't feel anything in his body.
Shiba: wrong move Karin
Karin: damn it
Yamasaki: watch out Karin
Shiba pushed both Yamasaki and Karin down to the ground while he was pulling out the sword t his body.
Kanemura: don't worry Nissan I will save you no matter what happens
Shiba: I wish you good luck Kanemura
Kageyama: Tamura and Yui-san need to protect Kanemura to save Shiba's life from taking control over the dark self
Kobayashi and Tamura are going to follow Shiba everywhere he goes somewhere to the building place.
Shiba: please stop following me
Tamura: Kobayashi use that thing on him
Kobayashi: okay I will do
Out of the blue, Kobayashi and Tamura were using the rope at him and he fell to the ground.

Without any sound, Kobayashi and Shiba had control of everything to them but he can't get hurt Kageyama or others.
Shiba: tell Kanemura to never meet me ever again
Kageyama: wait...don't go
Tamura: Shiba had gone but now we can't track him anything else
While Kageyama and other agents had come back to the Sakurazaka studio and she saw that Shiba is not coming with them.
Kanemura: where is Nissan?
Tamura: I'm sorry Shiba is gone disappear

When Kanemura was kneeling on the ground facing the floor crying over her brother's disappearance again.

Shiba's eyes glow dark red and suddenly Leo and Lugh come here to see Shiba are red eyes on their faces.
Leo: Shiba what have you done now

Inoue: Shiba...you have to fight it
Kanemura: Inoue?
Inoue: I can feel that he was fighting inside the body
He fought inside the body and Shiba still needs to have everything that Kanemura needs to stay with him all the time by his side.
Kanemura: I need to company him alone
Morita: okay but if he wakes up tell us immediately
