遥か彼方の大地にて今も劫火に焼かれ続ける魔王の剣。

数々の刀剣を所持した信長であるが、魔王に変生した信長が手にする剣はそのどれとも違う異形の魔剣であった。あらゆる信長の可能性の集まりである魔王信長同様、その剣も信長の所持したあらゆる刀剣の集まりであったのだ。

無劫の大地にて今も焼かれるその剣は魔王の帰りを待ち続け、無尽の時を立ち続けているという。

「名前？　聞いて驚くが良い、魔王が手による塵滅の魔剣、是即ち、―――『魔王剣』よ！」

……あ、剣がずっこけた。

In a faraway land, the Demon King's sword burns with destructive flame even today.

Although Nobunaga possessed many swords, not one saw any use once Nobunaga was reborn as the Demon King, replaced instead by an aberrant demon sword. Just like Demon King Nobunaga, it is a collection of various possibilities of Nobunagas. This sword is also an amalgam of all blades possessed by Nobunaga.

It's said that the sword continues to burn in oblivion, still waiting for the Demon King's return, standing upright for eternity.

"Its name? Brace yourselves! Since it's a demonic sword that burns all to ash in the hands of the Demon King...it's called the 'Demon King Sword!'"

...Uh-oh, the sword fell over.
