| [00:15.24] | 「ヒラく宇宙ポケット」より |
| [00:19.09] | |
| [00:36.90] | アブない... 痛くない... |
| [00:38.49] | 傷つけられたし 到底解んないこと言われたし |
| [00:42.16] | もう疲れた |
| [00:43.16] | いつまでだ？ |
| [00:44.11] | 光など見えない |
| [00:45.67] | そう 捕らわれたこのgushy and boo |
| [00:48.25] | 静かに夢組み立て... one night |
| [00:50.82] | 抜け出したい 離れたい 不可能だと言うの？ |
| [00:53.81] | Get your wild chance |
| [00:55.10] | Get my best ship, best way |
| [00:59.39] | 記憶が解（ほど）けてく |
| [01:01.72] | 夢から覚めた |
| [01:04.34] | だから目を閉じない |
| [01:07.06] | 全てが見える |
| [01:09.71] | このままじゃ壊れる |
| [01:12.43] | その箱を守りたいなら |
| [01:17.04] | 覚悟して さあ 改めて！（It's flashback だから確かめたい） |
| [01:22.26] | 逃亡中 攻撃中のふらついたmind |
| [01:24.88] | 現実突き立てられ あぁ... |
| [01:27.43] | 気持ち良いことだけしたぁぁぁい！！ |
| [01:30.94] | 少しだけ... 少しだけ...少しだけ良いの？ |
| [01:34.10] | 後から気付けばコワい話 |
| [01:36.51] | lost your big mouth |
| [01:37.80] | lost my true face |
| [01:39.08] | no more... |
| [01:41.76] | 記憶が解（ほど）けてく |
| [01:44.41] | 夢から覚めた |
| [01:47.02] | 囲いなどいらない |
| [01:49.78] | 全てが聞こえる |
| [01:52.41] | このままじゃ飛べない |
| [01:55.10] | 泥にまみれた羽なら |
| [01:59.75] | 覚悟して さあ 切り離して |
| [02:04.57] | |
| [02:25.26] | -あなたは白？ |
| [02:27.74] | 私は黒... |
| [02:30.24] | それは、正しい？ |
| [02:32.67] | それは、本当に正しい？ |
| [02:36.78] | いつか交わることが出来るなら |
| [02:40.51] | 全て 死なない...- |
| [02:43.41] | |
| [02:46.04] | 今押し寄せる 進化の海 |
| [02:50.42] | 時が来る |
| [02:53.95] | |
| [02:56.45] | うねる波に 目がくらむけど |
| [03:01.13] | 誤った解なら 今すぐ改めて！ |
| [03:08.77] | |
| [03:19.61] | 黒と白の上で |
| [03:30.12] | 解けて行くよ...... |
