This is a world with all technology in the skill tree. Logically speaking, it cannot communicate with the fantasy world. However, because of a certain god who accidentally entered this world twenty years ago, this world was noticed by the devil in a certain fantasy world. Finally, this year, the Demon King opened a rift between the two worlds and began to send demons to this world through the cracks in time and space in an attempt to conquer it. Four guardians appeared in this world.
The four of them not only want to prevent the invasion of demons, but also avoid being shocked by the people of this world who discover the truth. They also need to find a way to seal the cracks in time and space.
As for their names. . . It's too late to think about it, save the world first.
(There are a lot of tokusatsu and kensan stalks ahead (probably)
