Kai was a 17-year-old dropout. A NEET. A background character in real life with nothing to his name but bitterness, novels, and guilt. After his parents died, he gave up on the world. People were fake. Dreams were pointless. And that one novel he kept reading? He hated it especially the main character, June. Perfect, noble, always standing tall. Everything Kai wasn’t.Then, one night, a voice asked: “What if you did meet June?”He said yes, half-asleep and half-mocking.Now he’s trapped in the novel. Isikeid. But he’s not June. He’s not a hero. He’s not even in the main cast.He’s an extra in the background of a world he knows too well and he’s had enough of watching things play out the same way. This time, he’s going to change everything. Whether the world likes it or not.

Darkness is coming, and crisis is everywhere. In this long dark and desperate night, do you want to see a bonfire with warm words? We are that light.

We don’t want to be the little bully who guards one-third of an acre and eats canned food.

We don’t want to drive the harem on a great escape from east to west.

We don’t want to be a bunch of rats guarding rancid cheese in the gutter.

We don’t want to see the panic on your faces and the desperation in your screams.

So we stand up, fight for ourselves, fight for you, fight for humanity!

As long as we are here, the flames of war will never be extinguished.

We light a warm bonfire in the dark night, and watch the dawn with the brilliance of life.

We are the shield of the earth, the patron saint of mankind!
