A knife sprang out then Quicker than uneventful tears You know, disappering now would be pointless Like candle wax, harden, my waltzing blood Despite there being so many unheld hands Hey, what happens when you die?

Who will you haunt then? Like arrows, the seasons pass by Regrasping that which you won't give up If forgiven, just forget, every little thing Kindess halts towards the destined home To a turned back, a sorrowful gaze follows Repeating "Thank you" and "I'm sorry" Taking that step, 01

Always hoping for a better future somewhere, If you're going to accept the misfortune of resisting life, seek freedom Our red creations are driving us into turmoil Embracing this inexplicable reason, we sing today.

ここで人間辞めました！ 重ねたラヴゲームもうたくさんでした 切るスイッチ見当たらなくなってどれくらい はじめからなかったか ゼロが並べば安心ですか？ 「代わりがいる」なんて言わせたくなかった さみしさの果てひとり踊れますか 錆びたナイフ捨て時は逃した 渇かないでこのままダンスダンスワルツ ねぇそっちはどうですか？

さよならがその静けさが澄み渡る さあここがはじまり 「目を逸らすな」言い聞かせては 最後のはじめましてよろしく 「眠らないで」身体が叫んでる 早鐘を打て浮き彫りのハート 言い残した言葉じゃ頼りないから いつも踏み出す01

Here, I quit being human I've had enough of these recurring games of love How long has it been since the off switch disappeared? It wasn't there from the start Do you find comfort when zeroes line up? I didn't want to let you say, "There's a replacement" Can you dance alone at the end of loneliness? You missed the chance to throw away that rusted knife Don't thirst, just dance, dance, waltz Hey, how's it over there?

Goodbye, the silence is crystal clear Well, this is the beginning "Don't look away", I tell myself Nice to meet you for the last time "Don't sleep", my body screams Strike the early bell, embossed heart Words left unsaid are unreliable Always stepping forward 01

Always hoping for a better future somewhere, If you're going to accept the misfortune of resisting life, seek freedom Our red creations are driving us into turmoil Embracing this inexplicable reason, we sing today.
