|kan1=
きらきらと瞬いて　雨のように弾ける
たくさんの輝きが　ぱらぱら降り注ぐ
|kan2=
ひらひらと漂って　かわいい頬を彩る
たくさんの煌きが　ふたりを包み込む
|kan3=
きらきらと瞬いて　飴のように転がる
たくさんのときめきがさみしさ吹き飛ばす
|kan4=
流れ星に届くまで　空を飛ぼう　ふたりで
|kan5=
永遠に変わらないものを探して　求めて　辿り着いた
星空へ続く銀の塔の先に何が待っているのだろう
|kan6=
あなたが生きる時間とわたしの生きるそれ
|kan7=
交わらないままで歩むのはふたりこれ以上できないから
あと少し踏み出して　このままふたり　幸せになろう
|kan8=
永遠に変わらないものを探して　求めて　辿り着いた
星空へ続く銀の塔の先に何があるのかを
|kan9=
そっと　お願い　誰か教えて

|eng1=
Thousands of lights fall dancing like rain
Twinkling and sparkling as they pour from the sky
|eng2=
Thousands of lights, embrace us both
Drifting and swirling, coloring your cute cheeks
|eng3=
Thousands of fluttering pulses blow away loneliness
Twinkling and sparkling, rolling about like candy
|eng4=
Until we reach those shooting stars, let’s fly through the skies together…
|eng5=
Searching, seeking for something that will never ever change, we’ve come here
What lies waiting for us beyond that silver tower stretching across the sky?
|eng6=
The time in which you live and that which is what I live…
|eng7=
If we continue to walk along like this unchanging, there is no more we can do
But if we press on just a little farther, I’m sure we’ll find happiness
|eng8=
Searching, seeking for something that will never ever change, we’ve come here
What lies waiting for us beyond that silver tower stretching across the sky?
|eng9=
Please, Someone, Tell me…
