Kiriyama plans the lead character Moriyama Shinichi nicknamed Mirage who is a top agent within K-13 who doesn't show any emotions and rarely speaks. With regard to his character, Kiriyama revealed that he went through the 1st episode's script and found that he only had two lines, of which one was "ryoukai" (I understand). As such, he has to rely on his eyes to show his character's emotions since he can't speak in the drama. On the other hand, Kaname who plays the section chief of the special public security team, has to do most of the talking in order to "cover" for Kiriyama's character. As for Sano who plays a genius hacker, she revealed that she had to attend a hacker's seminar and undergo training by a hacker who had won contests. For Takeda who plays the real estate magnate at odds with K-13, he commented that the style of this drama is similar to his signature work "NIGHT HEAD" as the key characters do not know who they are up against from the start and can't see where they are heading.
