Lyrics
<poem> 開け! 明日のトビラ 未来はまだ 果てしなく遠いけど 運命の鍵はこの手の中に…!
決められてる レールの上 はみ出して歩いた 不安と期待という 足跡残して
見上げた空 白い雲 まっすぐ流れてる 「自分を信じるコト」 それがミチシルベ
みんなと逢って 強くなれた気がするよ 一人じゃ叶わない 願いの輝きを探しにゆこう
旅は続いてゆく ひとつひとつ超えながら せつないほど 胸に秘めた 誓いを抱きしめて 開け! 夢のトビラ 目指す場所へ 導いてく紋章(しるし)は 希望を照らした光を放つ
可能\性を束にして 所持(ホルダー)してるから どんなに暗い闇も 立ち向かいゆける
つまずいたって 顔をあげた その先に 見慣れた笑顔たち それだけで心は元気になる
想いを重ねたら 怖いものは何もない 同じ奇跡分かち合って つながりだす絆 開け! 時のトビラ 無限の中 駆けめぐる魔法(マジック)で 新たな世界が動きだしてる
星がきらめく頃 そっと綴るストーリー 悲しみにも意味があると 解りはじめてるから 開け! 明日のトビラ 未来はまだ 果てしなく遠いけど
運命の鍵はこの手の中に…!

Open! Door of tomorrow
Though the future is far away
It's neverending
The key to destiny is in my hands...!
I was determined
I walked along
On the edge of the rails
Leaving footprints
Known as worry and hope
I gazed up at the sky
The white clouds
Flowing straight ahead
"I believe in myself"
That's my guidepost
Meeting with everyone
I feel that I've become stronger
On my own it hasn't come true
I'll go search for the glow of hope
My journey continues
While I go on, piece by piece
There's a pang of sorrow hidden in my chest
I'm holding onto my vow
Open! Door of dreams
To the place I'm aiming for
My guiding symbol
Emits a light that illuminates hope
Since I'm the holder (owner)
I bundle up the possibilities
I can fight against the darkness
No matter how dark
I stumbled
But then lifted my head
To those familiar smiles
My heart cheers up by itself
If I pile up wishes
There's nothing to be afraid of
Sharing the same miracle
The bonds that tie us together
Open! Door of time
In infinity
A new world comes alive
With magic running wild
The stars are sparkling time
A softly composed story
Because I begin to understand
That there's even meaning in sorrow
Open! Door of tomorrow
Though the future is far away
It's neverending
The key to destiny is in my hands...!
