"A world where monsters, dragons, and even gods exist.

To face them, the weapons of humanity in this world were far too pathetic.

However—

'T-This... is this really the Spear of Longinus that is said to kill even gods...?'

'Holy Sword Balmung... Are you saying a dragon can be sliced by a single sword like this?'

'The Sa-in-geom (Four Tigers Sword) that parts the waves just by swinging it in the sea... Incredible!'

Those kinds of things?

In Earth's mythology, you have to smash at least that much to be called a hero."
