Beginning

 The world he knew was gone. Friends, family, places he hung out...almost all of it vanished as quickly as blinking. By the time he had woken up in the hospital, only monsters remained. Though there were occasionally friendly demons such as Pixie, others were less so, hungry for his flesh. And even after escaping, all that awaited him were ruined buildings and a vast desert. Humanity was seemingly gone.

As he walked past the park, still journeying with the Pixie companion he had, he saw a figure wandering about. Seemed human enough? Naoki wanted to believe someone was alive.  Maybe there were more survivors than he originally thought. Carefully he approached them, taking slow steps behind them. At a decent enough distance, he finally called out.

"Hey! You're human, right?"
