Fantasy imagination + Cthulhu style + grand world view + fierce protagonist + exciting fighting + single female protagonist without a harem + high-profile supporting roles
The protagonist who was almost killed at the beginning, in the coming desperate world, how to break his fate step by step and transform into the ancestor of all ways, save all living beings and bring vitality to the world.
The legend is just a matter of course
all just because
Only by fighting can there be hope!
Don't like it very much
