About this game
Story
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...?
Become the Oni Slayer
Name yourself and be the hero! Your legend begins now!
Once the battle is won, it's time to relax and enjoy your victory with your friends.
...But the story doesn't end after the credits roll...
Think the story stops at "happily ever after?"
You might just discover secrets beyond defeating the evil Yamakui after the final battle.
The greatest treasures are the friends (and memories) you make along the way~
9 ending variants and 1 true ending!
...Will you discover them all...?
