Mouryou no Nie

Centuries ago, people fought terrible creatures and evil creatures, and this battle was extremely difficult. After long battles with hordes of monsters, humans imprisoned their remains in the depths of the mountain. However, from time to time, some of these creatures can still be found on the surface.

Hayato, Chihiro, and Suzu are hunters who search for and seal hidden monsters. Soon the ancient seal will weaken, and our heroines will have to save the world from the invasion of these creatures.
