海の中 泳いで
差し込む 光の間
君と亦 二人で
溶け込む 夢の中で
夢の中 彷徨い
掻き出す 悪夢の欠片
隙の無い 幽世に
囚われ 海の底へ
どうしても逢いたい
人がいるなら
壊してもいいから
前に進もう
斬り裂いて閃光 潜り抜け
泣いて掴んだんだ
知らないで炎上 飛び越えて
闇で待ってたんだ
逢いたかった 全ての人へ
サヨナラ
暮れていく 東の空
湧き立つ 自分の涙
連れていく 幽世に
捉えて 君の元へ
声にして叫びたい
事があるなら
壊してもいいから
叫び続けよう
霧割いて潜航 潜り抜け
やっと掴んだんだ
知らないで炎上 飛び越えて
光を待ってたんだ
逢いたかった 失くしたくなかった
去りたかった 残りたくなかった
全ての人
あらゆる世界 私と混ざれ
サヨナラ
斬り裂いて閃光 潜り抜け
泣いて掴んだんだ
知らないで炎上 飛び越えて
闇で待ってたんだ
霧割いて潜航 潜り抜け
やっと掴んだんだ
知らないで炎上 飛び越えて
光を待ってたんだ
逢いたかった 全ての人へ
