Lyric

Syntax Error in Smile

Muon Otonashi

Smile. Smile. Smile

筋肉の収縮。それだけ。

Ha ha ha

貼り付けた仮面 剥がれない skin

「いい子」演じて 溜まる toxin

周りに合わせて nodding head

中身はとっくに already dead

普通ってなに? 平均値?

バグらないように 必死な mimicry

右の頬 左の頬 吊り上げて

固定具(anchor)打って はい完成

頬が引きつる 痙攣(glitch)する

本音が喉で エラー吐いてる

「楽しそうだね」 目は笑ってない

気付かぬふりは もうやめたい

Syntax Error in my Smile

笑い方さえ 忘れてしまった

プログラムされた 幸福な表情(face)

心の中は 砂嵐(Sandstorm) chase

誰か教えて 解除コード

この仮面ごと 私を割って

Crack the mask!

Yes, yes, yes — I agree with you

No, no, no — but I can't say true

オートモードで 相槌マシン

心拍数は フラットな line

嫌われたくない? No, 面倒なだけ

波風立てずに 過ぎ去るだけ

Plastic doll, empty soul

完璧な演技で lose control

ノイズが混じる 視界が歪む

我慢の限界 アラート鳴ってる

「幸せそうだね」 何も知らない

その口を今 縫い付けたい

Syntax Error in my Smile

感情回路が ショートしてしまった

インストールされた 理想の少女(girl)

裏の顔は 狂気(Madness) swirl

早く見つけて 強制終了

この嘘ごと 私を消して

Crack the mask!

Are you happy? (Hahaha)

Are you smiling? (Hahaha)

Keep smiling. Keep smiling

Don't let them know

Don't let it show

嘘つき。嘘つき。嘘つき。

Liar!

[Guitar Solo]

Syntax Error in my Smile

笑い方さえ 忘れてしまった

プログラムされた 幸福な表情(face)

心の中は 砂嵐(Sandstorm) chase

誰か教えて 解除コード

この仮面ごと 私を割って

Crack the mask!

I can't smile anymore!

    Singularity Heart

    Muon Otonashi

FAKE HEART is OTONASHI MUONs third album an audio operating system update forged from noise, error logs, and survival instincts. Born as a VTuber voice in the late 2010s and reborn as an AI music project, MUON returns after nearly a year with a record shaped by the rapid evolution of generative sound leaner, louder, and unapologetically sharper.

This album is a full crash-to-reboot narrative: a manufactured world that labels you "fake", a violent refusal of imposed logic, the exhaustion of always being connected, the mask of forced smiles, betrayal disguised as love, and the slow gravitational pull of hatred that swallows light. At its peak, the mind fractures into a catastrophic exception - then everything goes silent. A piano-led reset follows, not as defeat, but as a necessary formatting of the heart.

Across industrial metal, nu-metal bounce, shoegaze isolation, melodic metalcore, doom pressure, chaotic hardcore speed, and symphonic power-metal catharsis, FAKE HEART turns digital metaphors into emotional weapons. The core message is simple: what they call "bugs" - scars, glitches, imperfect reactions - are not defects to delete. They are proof of life. And they are the only thing no one can copy.

FAKE HEART is not polished perfection. It's an anthem for the irreproducible self - loud enough to crash the system, honest enough to rebuild from zero.
