Yes but I just had an Idea lmao and im not gonna say it because someone might steal my Idea before I finish it.

Description: Helix Underswap: Mild Rain The monsters hid in a secret place in waterfall, the human had wandered around gaining LV and destroying area's with the true knife, the true knife destroyed every other place other than waterfall, and then the human went through the barrier and never returned, forcing the monsters to adapt to waterfall and use water magic. Aliza was the next human to fall.. seeing their inability to use determination, the monsters welcomed them to the family.
