Opening Theme 1

Traveller's Song (旅人の唄 Tabibito no Uta) is the first opening theme of the Mushoku Tensei anime performed by Yuiko Ōhara. It was released as a digital single on the anime's official premiere day on January 10, 2021.

The song was first used in the anime as the end-credits theme song for Episode 1. It officially debuted as the opening theme from Episode 3 and was used as the theme from the episode onwards. The song does not have a special video-animation sequence for the credits as it is integrated into real-time scenes of the story, and varies for every episode.

A collection of creditless opening videos for episodes 3-5 was included in the Blu-ray Chapter 1 release.

Lyrics
満ち足りぬ心に 溢れ出す水が 癒し与え
 * -|Japanese=恐れるなら　山を越えてゆけ

想像の上　誰も立てぬ場所 慈しみひとつ恋しさを持てば 手にする愛

静寂を知る風の声は 止まり木をしならせ 二度として同じ空 見せぬと唄う

微睡みの中　続くことを願い 夢なら　振り向かずに

想像の上　誰も立てぬ場所 指先にひとつ交わす約束は永遠

溢れ出す祈り 癒し与え

さよなら　さよなら 過ぐる日の私よ さよなら　さよなら 記憶は残せぬ

想像の上　誰も立てぬ場所 慈しみひとつ恋しさを持てば 手にする愛 Michitarinu kokoro ni afuredasu mizu ga Iyashi atae
 * -|Romaji=Osorerunara yama o koeteyuke

Sōzō no ue dare mo tatenu basho Itsukushimi hitotsu koishi sa o moteba Te ni suru ai

Seijaku o shiru kaze no koe wa Tomari ki o shinarase Nidoto shite onaji sora Misenu to utau

Madoromi no naka tsuzuku koto o negai Yumenara furimukazu ni

Sōzō no ue dare mo tatenu basho Yubisaki ni hitotsu kawasu yakusoku wa eien

Afuredasu inori Iyashi atae

Sayonara sayonara Suguru hi no watashi yo Sayonara sayonara Kioku wa nokosenu

Sōzō no ue dare mo tatenu basho Itsukushimi hitotsu koishi sa o moteba Te ni suru ai Those waters that overflow, They are like a blessing that heal my dissatisfied heart.
 * -|English=If you are afraid, Go over the mountains

In my imagination, I see a place where no one has ever stepped. If you have one compassion and love, You will achieve it

The wind that knows silence Bows a perch And sings a song Saying it won't show the same sky twice

While I was falling a sleep, I was wishing to last If it's a dream, don't turn around

In my imagination, I see a place where no one has ever stepped. One promise we make is an eternity

An overflowing pray Let it heal

Good bye, good bye The me from the past Good bye, good bye I won't leave my memories behind

In my imagination, I see a place where no one has ever stepped. If you have one compassion and love, You will achieve it
