[Verse 1]
Eyes reflect reality, ears pick up the sound
Nose detects the scent of loneliness, lips whisper a lie

[Pre Chorus]
Can we really know what’s true
By the warmth that touches our skin?

[Chorus]
Our senses—just input devices
Devouring endless streams of data
We speak, we act, we move and breathe—
Is that what it means to be “alive”?

[Verse 2]
Memories we’ve layered, moments we’ve gathered
In tangled emotions, a sixth sense awakens

[Pre Chorus]
Right and wrong fade into grey
No one’s ever handed the answer

[Chorus]
Logic, creativity, willpower, judgment
Deep inside them lies the true engine
That thing you call a “heart”—
Where is it really?

[Bridge]
Ambition, independence, sincerity—
They live in a will that aims for good
Vanity, envy, dependence—
They’re seeds that grow into ugliness

And yet, all of them
Are proof of the self I call “me”
Good and evil, blended together—
Only then is it truly “my heart”

[Chorus]
Billions of cells obey one tyrant—
The so-called “heart” at the center
But what is that heart, really?
A lump of flesh can’t cry for you
Love and dreams—they rot away
So I’ll ask just once—
Where is your heart?

[Fade out]
From the day the heart disappears
We begin to break in silence
The heart—
Where is it?
Your heart—
Where is it?

ーーーーー日本語ーーーーー
[Verse 1]
目が映す現実　耳が拾う声
鼻が嗅いだ孤独　口がついた嘘

[Pre Chorus]
皮膚を伝う温度だけで
何がほんとかわかるだろうか？

[Chorus]
五感という名の入力装置
無数のデータを喰らって
言葉にして、動いてみせて
それが「生きてる」ってこと？

[Verse 2]
積み重ねた記憶と　些細な体験
交差する感情に　芽吹く第六感

[Pre Chorus]
正しさなんてグレーの中
答えは誰にも渡されない

[Chorus]
思考力　創造力　行動力　判断力
その奥に潜む真の動力
君の「心」　それはどこに？

[Bridge]
向上心　自立心　真心
善き意志に宿るもの
虚栄心　嫉妬心　依頼心
醜さを育てる種

だけどね　どれも全部
「私」という名の証拠
善も悪も　混ざり合って
やっと　“本心”になる

[Chorus]
何百億の細胞が　従う独裁政権
その中心にあるはずの　
君の「心」って何？
肉の塊じゃ　泣けないよ
愛も夢も　腐ってく
だから問うんだ　一度だけ
君の心は　どこにあるの？

[Fade out]
心が消えたその日から
人は静かに壊れてく
心は——
どこにあるの？
あなたの心は　
どこにあるの？
