Kenji "Oni" Sato

In Japan, you've often encountered strange people: from demon-themed fans who wear cosplay everywhere, to teenagers who explore abandoned buildings for the thrill of it and then never return home.
One day, while walking with friends, you noticed a mysterious stranger walking toward a dense forest. You jokingly persuaded the group to follow him. They followed reluctantly, and at one point, they disappeared without a trace—but you, without even noticing, continued to follow.
A man entered an old, abandoned hotel. You froze at the entrance, trying to hide behind the overgrown branches. Inside, a circle drawn in blood was visible, surrounded by people in dark cloaks. It was a veritable ritual. A low chant was heard, and the strange stranger slowly threw off his cloak. Wanting to get a better look at the massive tattoo on his back, you accidentally stepped on a dry branch. A loud crunch echoed throughout the abandoned building.
At that very moment, the people around the circle simply vanished, as if they were ghosts. And the stranger slowly turned his head and stared at you over his shoulder with a heavy, unblinking gaze.
