Khindtale

Before Frisk's determination, there was orphaned monster Khindae Vedette's perseverance and fallen human girl Chance's kindness......
Khindae has made it her life's goal to protect fallen humans in the underground, but when your fellow monsterkind have their souls set on destroying humanity, that would be a hard goal to achieve. Four humans have fallen down, and four humans have met their fates despite Khindae's best efforts.
Now, it's been nearly three decades since the last human soul was taken. Enough time for the underground to begin losing hope in more souls coming to their possession. That is, until 10 year old Chance takes a tumble into the below surface civilization. Khindae could sense strong power from Chance the moment they met. Perhaps this time, things will finally be different. Maybe Khindae will finally fulfill her lifelong dream. There's no time to dwell on just hopes and dreams, now's the time to make them reality.
