生まれ 出でづる火の中で

千の 槌音（つちおと） 浴びて立つ

美しき魂 宿す刃

無垢なる 銀の刀身

はじめて 触れた温もり

清き願いを 託されし

​[Chorus]

あぁ、いつしか

斬鬼と名付けられ

時代を駆ける 夢を見る

血潮に染まる 宿命など

知らぬまま ただ輝いた

ああ 我は妖し（あやかし）

幾多の夢を 斬り裂いた 悲しき魂

​[Verse 2]

時は戦国 武士の鞘

誉れと共に 敵を討ち

忠義の証と崇められ

次なる主は 兵の誉れ

しかし 世は移り 平和の影

研ぐ掌も 寂しげに

やがて我は 売られていく

幾度となく 人の手を

​[Hook]

その度に 闇の色 濃くなる

鉄に染み付く 怨念の跡

人の悪意と憎しみを

吸い込み 我は変わってゆく

​[Chorus]

妖しの刀 斬鬼

穢れた名を抱きしめて

もう 戻れぬ この因果

抗う術を持たぬまま

ああ 我は妖刀

幾多の夢を 斬り裂いた

悲しき魂

​[Bridge]

最後の主は 闇に潜む

罪なき人を 襲いし者

「もっと斬れ」と狂気の声が

我を突き動かす 意思なきままに

魂の叫び 虚しく響き

止められぬ 血の渇き

​[Verse 3]

朝焼け前の 辻の角

冷たき 露に濡れながら

幾多の 生命 奪ったか

もはや 数える術もなし

我の輝きは鈍色に

穢れの深さに 打ちひしがれ

​[Outro]

斬鬼の名は 畏怖となり

恐れられし 妖刀として

永遠に生きる 呪い抱く

錆びゆく心 氷つき

誰にも 愛されず

鞘に眠るは ただの鉄

哀れなり

あぁ、哀れなり

​[Ending]

（English Version）

​[Verse 1]

Born and coming out in the fire

Standing under a thousand hammer blows

A blade housing a beautiful soul

The pure silver body of a sword

The first warmth I ever touched

Entrusted with a pure wish

​[Chorus]

Ah, before I knew it

I was named Zanki (Demon Cutter)

Dreaming of dashing through the ages

Unaware of the fate of being stained with blood

I simply shone

Ah, I am an Ayakashi (phantom/demon)

A sorrowful soul that cut through countless dreams

​[Verse 2]

In the Warring States period, a samurai's sheath

Striking down enemies with honor

Worshipped as a symbol of loyalty

My next master, the pride of a soldier

But the world changed, and the shadow of peace fell

The hand that sharpens me grew lonely

Eventually, I was sold off

Passing through countless human hands

​[Hook]

With each time, the color of darkness deepens

The mark of resentment stained onto the iron

Absorbing human malice and hatred

I began to change

​[Chorus]

Zanki, the Ayakashi blade

Embracing the defiled name

This cycle of karma, I can no longer return from

Without the means to resist

Ah, I am a Youtou (demon sword)

A sorrowful soul that cut through countless dreams

​[Bridge]

My final master lurks in the darkness

One who attacks the innocent

A voice of madness, "Cut more!"

Drives me without my own will

The scream of my soul echoes in vain

The thirst for blood, it cannot be stopped

​[Verse 3]

At the corner of the crossroad before dawn

Drenched in cold dew

How many lives have I taken?

There is no way to count anymore

My gleam is now a dull color

Crushed by the depth of my defilement

​[Outro]

The name Zanki became fear

As a dreaded demon sword

I embrace the curse of eternal life

My rusting heart freezes over

Unloved by anyone

Sleeping in the sheath is just iron

How miserable

Ah, how miserable

​[Ending]
