黒炎の誓い (Kokuen no Chikai – Oath of the Black Flame)

[Intro (Heavy guitar riffs with shamisen lead, thunderous drumbeats, and soaring violin harmonies):] 闇の中で揺れる炎 深紅の空が道を裂く 罪と罰が織りなす夜に 刃を掲げ戦いを挑む [Verse 1 (Driving guitar rhythm, shamisen weaving melody with sharp violin accents):] 千年の呪いに縛られた魂 絶望が胸を焼き尽くす 仇の名を叫ぶたび強く 夜空を裂く黒炎が燃ゆ [Pre-Chorus (Rising tension, layered vocals and violin build anticipation):] 運命を背負う者たちよ この刃に力を与えよ [Chorus (Explosive instrumentation, vocals soaring with intensity):] 黒炎の誓いを掲げて 全てを切り裂く運命の刃 闇を越えて未来を掴め 希望の光が導くまで [Verse 2 (Softer tone at the start, shamisen and violin in unison, gradually building up):] 沈黙の森に潜む影 忘れられた神々の怒り 血に染まる運命の輪を 断ち切る勇気を胸に秘めて [Pre-Chorus (Drums intensify, shamisen and guitar harmonize):] 運命を背負う者たちよ この刃に力を与えよ [Chorus (Repeat with additional violin flourishes and harmonized vocals):] 黒炎の誓いを掲げて 全てを切り裂く運命の刃 闇を越えて未来を掴め 希望の光が導くまで [Bridge (Instrumental solo featuring shamisen, violin, and a shredding guitar riff): (Shamisen starts with a mournful yet resolute melody, violin rises in a crescendo, leading into an electrifying guitar solo. Drums accent the shifts in dynamics.)] [Breakdown (Slow, heavy rhythm with whispered vocals and shamisen):] 罪と誓いが交差する刹那 選ばれし者の涙が流れ 復讐の炎に包まれながら 新たな光を探し求める [Final Chorus (Full orchestration, maximum intensity):] 黒炎の誓いを掲げて 全てを切り裂く運命の刃 闇を越えて未来を掴め 希望の光が導くまで [Outro (Shamisen and violin fade into a haunting melody, vocals softly echo):] 黒炎よ、消えることなき誓い 新たな世界を照らし続けよ [End Song]
