Those who died writhing in the pangs of illness.

Those who were eaten alive by insects or beasts.

Those who were swallowed by the flames or snowstorms overflowing from Hell.

Those who had the world as their enemy, and were defeated by it.

Many have died, haven't they? Our children, our grandchildren...

If we want to avoid any more sacrifices, we have no choice but to overcome the world of oni.
