原歌词
| [00:12.06] | 鎖した 掌（てのひら）の中 |
| [00:17.26] | 幽かに、瞬く |
| [00:22.58] | 一筋 |
| [00:24.62] | その誓いに、縋るやうに |
| [00:29.94] | 生きていた |
| [00:33.01] | |
| [00:34.07] | 揺れ動いてる |
| [00:39.43] | 独楽（こま）の様に曖昧な |
| [00:44.49] | 想いだけ、遺（のこ）したのは？ |
| [00:51.64] | ありのままに |
| [00:54.25] | |
| [00:54.94] | 束縛（とら）われてたのは |
| [00:58.47] | 僕の心の奥で、燻（くすぶ）った愛 |
| [01:05.57] | 狭間で揺れ動く |
| [01:09.27] | 蛍の光が、眩しく |
| [01:16.64] | |
| [01:17.31] | 手を伸ばせば |
| [01:22.36] | 遠のくものだけ |
| [01:27.10] | 惹かれゆくよ |
| [01:33.72] | |
| [01:36.20] | 血潮に |
| [01:37.86] | 微睡（まどろ）みながら |
| [01:41.52] | 描いた、軌跡は |
| [01:47.12] | 水泡（あぶく）に |
| [01:48.99] | 消えていく |
| [01:52.41] | あの日の靄（もや）、晴れないね？ |
| [01:57.69] | |
| [01:58.29] | 研ぎ澄ました |
| [02:03.61] | 剣の先に、浮かんでる綻び |
| [02:11.43] | 耳澄ませば |
| [02:15.81] | ありのままに |
| [02:19.16] | |
| [02:19.52] | 掴みかけたのは |
| [02:23.19] | 君の頬、流れゆく、哀しい残響（おと） |
| [02:30.27] | 秘かに歩み寄る |
| [02:34.03] | ふたりの行き先、昏くて |
| [02:41.27] | |
| [02:41.87] | 風薫れば、散ってゆく花、綺麗 |
| [02:53.26] | 追いかけては |
| [03:03.79] | |
| [03:23.22] | どんな時も |
| [03:28.64] | もう、離したくはないと |
| [03:33.79] | 抱き締めてく、幻影（まぼろし）を |
| [03:40.86] | ありのままに |
| [03:43.59] | |
| [03:43.99] | 束縛（とら）われてたのは |
| [03:47.70] | 僕の心の奥で、燻（くすぶ）った愛 |
| [03:54.75] | 狭間で揺れ動く |
| [04:00.81] | |
| [04:01.80] | 束縛（とら）われてたのは |
| [04:05.41] | 僕の心の奥で、燻（くすぶ）った愛 |
| [04:12.51] | 狭間で揺れ動く |
| [04:16.22] | 蛍の光が、眩しく |
| [04:23.00] | |
| [04:24.11] | 手を伸ばせば |
| [04:29.30] | 遠のくものだけ |
| [04:34.62] | 惹かれゆくよ |
| [04:43.05] | 鎖した 掌（てのひら）の中 |
| [04:48.79] | 幽かに、瞬く |
| [04:54.46] | 蛍の その命を、護る為に、生きていく |
| [05:06.82] |
歌词翻译
| [00:12.06] | 掬一萤在手 |
| [00:17.26] | 朦胧间闪烁 |
| [00:22.58] | 仅微光一点 |
| [00:24.62] | 依靠誓言般 |
| [00:29.94] | 苟延残喘着 |
| [00:34.07] | 晃动摇摆着 |
| [00:39.43] | 陀螺般摇摆的 |
| [00:44.49] | 想法后，还剩几何 |
| [00:51.64] | 陈旧不变 |
| [00:54.94] | 被束缚住的 |
| [00:58.47] | 吾心深处，薰灰的爱 |
| [01:05.57] | 在狭处挣扎 |
| [01:09.27] | 萤火光芒，太耀眼 |
| [01:17.31] | 伸出手的话 |
| [01:22.36] | 连远处的云 |
| [01:27.10] | 都触手可及 |
| [01:36.20] | 旧日狂热 |
| [01:37.86] | 都已沉睡 |
| [01:41.52] | 描绘成轨迹 |
| [01:47.12] | 成为泡沫 |
| [01:48.99] | 渐渐消失 |
| [01:52.41] | 那天的云霭，散了吗？ |
| [01:58.29] | 磨去棱角 |
| [02:03.61] | 剑锋开绽 |
| [02:11.43] | 侧耳倾听 |
| [02:15.81] | 往日依旧 |
| [02:19.52] | 奋力抓住的是 |
| [02:23.19] | 你的脸颊，流淌而下的悲伤印记 |
| [02:30.27] | 双方选择妥协 |
| [02:34.03] | 向着两个目的地，渐步迟暮 |
| [02:41.87] | 熏风微拂，花瓣凋落，如此凄美 |
| [02:53.26] | 就连追忆 |
| [03:23.22] | 都无处可寻 |
| [03:28.64] | 已无法归去 |
| [03:33.79] | 拥抱着，幻影 |
| [03:40.86] | 就这样吧 |
| [03:43.99] | 被束缚住的 |
| [03:47.70] | 吾心深处，薰灰的爱 |
| [03:54.75] | 在狭处挣扎 |
| [04:01.80] | 被束缚住的 |
| [04:05.41] | 吾心深处，薰灰的爱 |
| [04:12.51] | 在狭处挣扎 |
| [04:16.22] | 萤火光芒，太耀眼 |
| [04:24.11] | 伸出手的话 |
| [04:29.30] | 连远处的云 |
| [04:34.62] | 都触手可及 |
| [04:43.05] | 掬一萤在手 |
| [04:48.79] | 朦胧间闪烁 |
| [04:54.46] | 萤火之光，为你而燃，为你而活 |
