Onigashima

Play as the nameable Oni Slayer who defeated the infamous Yamakui, a monster that comes down the mountain to feed on villagers every red moon.

People tell your story, how the red moon fell, the monster was slain, and peace returned to the village.

But sometimes, the Yamakui's armor feels weird, and your friends say things you don’t remember.

The next red moon is supposed to be in seven days. It should be peaceful, because you slayed the Oni. Well, no matter what happens next, you’ll face it side by side, with everyone. Because you are a hero, and heroes never fight alone.

...Right...?
