The silver-haired man altered his stance. As soon as he gestured as if he held something in both hands, numbers scattered from them like sparks from a lighter’s flint: 1, 27, 5. Then a double-edged sword appeared in his hands.

The gigantic sword was nearly as tall as he was and looked like something from a children’s book.

It was the steel sword of a great king.

The man swung the giant sword diagonally down with both hands and the nonexistent blade dug deep, deep down into Mathers’ torso through his shoulder.

“A clay…more…?”

“This is a tribute, so rejoice, self-styled highlander. I finished you off with the sword you so loved.”

It did not matter here whether or not it physically existed. Either way, it tore through Mathers’ body and dark red liquid erupted from within.
