心が揺れている
My heart is shaking
理由は分からない
I don’t know why
正しいことを選んだはずで
I thought I chose what was right
でも何かが欠けてる
But something’s missing
言葉にできない違和感
An unspoken discomfort
胸に残ってる
Still stays inside
進んでいるのか
Am I moving forward
立ち止まっているのか
Or standing still
揺れる境界線の上
On this unstable line
答えはまだ見えない
The answer’s still unseen
間違っていたとしても
Even if I was wrong
ここにいる理由はある
There’s a reason I’m here
守れたものと失ったもの
What I saved and what I lost
重さは同じで
They weigh the same
後悔だけが静かに
Only regret quietly
足元を揺らす
Shakes my ground
逃げたい夜も
On nights I want to run
逃げられなくて
I can’t escape
揺れる境界線の上
On this unstable line
踏み出す勇気もなく
Without courage to step out
それでも時間は
Still, time keeps
僕を先へ運ぶ
Carrying me forward
壊れそうなのは
What’s about to break
世界じゃなくて
Isn’t the world
たぶん僕自身だ
It’s probably me
揺れる境界線の上
On this unstable line
答えはなくてもいい
Even without answers
この揺れを抱えたまま
Holding onto this sway
前に進めばいい
I can keep moving
まだここにいる
I’m still here

UNSTABLE LINE
RADIAL VECTOR
"UNSTABLE LINE" sits at the emotional midpoint of the album *AFTER THE WAVE*,
capturing uncertainty and inner conflict through restrained electric rock.
It exists in a space that is neither battle nor peace-
a moment where you cannot tell whether you are moving forward or standing still.
That ambiguity is the heart of this song.
With controlled beats, subtly pulsing electronics,
and male vocals that speak rather than shout,
the track portrays the anxiety before taking a step,
and the quiet will to keep moving despite the doubt.
"UNSTABLE LINE" is not a song that provides answers.
It affirms the act of standing firm, even while the ground continues to sway.
Artist Profile
RADIAL VECTOR
RADIAL VECTOR is a neon city electro rock unit that fuses electronic noise with aggressive rock energy. Defined by razor sharp guitar riffs, metallic breakbeats, and emotional vocals that shift between stillness and explosive intensity, the group builds a sonic world centered around contrasts destruction and rebirth, impulse and silence. Their music visualizes the pulse of a futuristic city: neon lights cutting through darkness, rhythms beating like electric circuits, and fragile human emotions igniting beneath layers of noise. Combining the emotional intensity of ONE OK ROCK with the electronic impact of Boom Boom Satellites, RADIAL VECTOR stands out as a unique force in the modern electro rock landscape.
