大事なおもちゃをなくす夢を見てた daiji na omocha wo nakusu yume wo miteta I saw a dream where I lost a precious toy
目頭がまだ熱で震えてた megashira ga mada netsu de furueteta The corners of my eyes were still hot and trembling
生きていくにはこんなに覚悟が必要だなんて思いもしてなかったんだ ikite iku ni wa konna ni kakugo ga hitsuyō da nante omoi mo shite nakatta n da I had no idea I'd need this much determination to keep living
子供だった kodomo datta I was just a child

どうしてそんなボロボロでも笑顔で居んの dōshite sonna boroboro demo egao de inno Why are you able to keep smiling despite looking so worn out?

星空は壮大だ 飲み込まれそうな今 hoshizora wa sōdai da nomikomare sō na ima The starry sky is so vast, it seems to suck us in right now
数百光年先ではすでに死を迎えてるかも sūhyaku kōnen saki de wa sude ni shi wo mukaeteru kamo But it might already be dead hundreds of light years away
それぐらいぼくらは近いようで遠い sore gurai bokura wa chikai yō de tōi That's how close and far apart we are
なにを選びなにを救いなにを捨て去りなにを得る？ nani wo erabi nani wo sukui nani wo sutesari nani wo eru? What will you choose, what will you save, what will you forsake, and what will you gain?

ちょっとしたことで動じる小心者返上する chottoshita koto de dōjiru shōshinmono henjō suru I'll stop being a coward who gets upset over small things
時にはどろんこさ 時にはやけくそさ tokini wa doronko sa tokini wa yakekuso sa Sometimes covered in mud, sometimes desperate
それでもいい 精一杯背伸びをして観測する soredemo ī seīppai senobi wo shite kansoku suru But that's fine, I'll try my best to grow up and observe
扇風機も全力で涼を送ってる senpūki mo zenryoku de ryō wo okutteru Even the electric fan is sending cool air at full power

Or potential for the future? Or potential for the future? Or potential for the future?

生きるとはそれを選ぶこと ikiru to wa sore wo erabu koto Living means choosing all that
さらなる扉が待ってる saranaru tobira ga matteru And there will be more doors waiting after that

Make your choice! Make your choice! Make your choice!
