The mister had what they call chuu-ni byou. He pretend like he's a comic hero or something and he's living in a fictional world. When his colleague called him in office, he played as if it could be someone sent by evil, or how that person hide his presence. The last panel, he call that ruler as a holy sword and he went on killing a clan of Yuuka-nyan like hero in quest to destroy a clan of evil.
I can't help but think of that guy from Persona 4, sounds a lot like him but without the TV world letting his distorted game views being represented outside of the real world.
