《Grateful Days》的歌詞如下：
龍の子さ この感謝を叫べ
Dragon Ash, shout out this gratitude
優しさに胸を焦がされ 夢を胸に抱きしめ
With the kindness in my heart, embrace my dreams
見つめ合えた喜びをも 共に唄おう
Sharing the joy of mutual understanding, let's sing together
今日も行こう 無垢な夢探しだ
Let's go today, searching for pure dreams
君と僕の道は晴れ渡る陽のあたる坂道
Your and my path is a sunlit slope that spans clear skies
あふれる想いに震えながらも 進むんだ
While trembling from overflowing emotions, we press on
駆け抜けろ どんな明日も待ちきれない
Let's run through it, we can't wait for what tomorrow will bring
感じ合える幸せに溺れてる
Drowning in the happiness of mutual empathy
悲しみにも目をそらさないで 今を摑んでいこう
Don't look away from the sadness, seize the moment now
僕らのDragonash grateful days
Our Dragonash, grateful days
僕らのDragonash grateful days 夢を抱きしめて
Our Dragonash, grateful days, embracing our dreams
どんな時も変わらない 君と僕の道を行こう
Let's walk the path with you and me, it will never change
龍の子さ この感謝に包まれてる?
Dragon Ash, are you being embraced by this gratitude?
