As for Mikami, the information given by the police described him as someone who enjoys taming others—"a sadist".
Wen Xishu had reason to believe… just like Mariko, Mikami could only maintain their charm and evoke certain things when in their latent period.
Mariko kept her human appearance constantly in order to trigger her lust, staying latent.
Similarly, Mikami also stayed latent to conquer Takahashi Fumihiko.
Wen Xishu was quite satisfied with the encounter of these two.
At the same time, this encounter left a card in Wen Xishu's hand unused. This meant that there could be one more "ghost" in the house.
Originally, in Wen Xishu's plan—
Mariko was meant to restrain Takahashi Fumihiko.
At this moment, bringing anyone else in would disrupt the situation. But now, Mariko did not need to restrain Takahashi Fumihiko anymore.
Takahashi Fumihiko could be restrained by Mikami instead.
With them restraining each other, Mariko's card was freed up.
