Berserker held the iron pole, over two meter long after being cut down, with two hands like a spear, putting a terrible pressure on Saber's sword. But the surprising point is that this weapon was nothing but an iron pole.

Saber's sword hidden under Invisible Air was definitely the holiest of the holy swords. It was the most supreme Noble Phantasm. There is no way it will have troubles against a piece of metal you pick up on the roadside.

The only thing that could possibly rival Saber's sword with such strength is the Noble Phantasm of another Heroic Spirit. Yet...

"Wh... at?"

Holding up, Saber couldn't believe her eyes.

The iron pole in Berserker's hands was being tainted in black. Black lines were spreading and multiplying like the veins of a leaf, invading the iron pole.

The starting point was Berserker's two hands. The black lines were spreading on the entire pole like a spider's web from where the black gauntlets are holding it.

This was Berserker's prana — the prana muddled with bloodthrist and hatred, possessed only by the black knight. The iron pole was receiving it by permeation from his hands.

"You can't mean...!?"

Saber understood through her surprise. The true nature of this Berserker's Noble Phantasm.

Lancer and Rider, watching closely, reached the same conclusion.

"... So that's it. When Blacky takes something, it becomes his Noble Phantasm."
