A Piece of dream sent to you Because from now on, it will become your own dream Without looking back, fly up with all your might Into that sky that resembles you You are my shining star My own super star (Dazzlingly bright) You are a shining star The heart that I've dreamed of That I cannot give up On the stage I've dreamed of Let's go up together, I won't leave you alone! Reach out, a Piece of dream sent to you Because from now on, I will become your own dream I'll show you a world no one has ever seen Always a Special smile sent to you I'll guide you to a place where you can laugh Without looking back, fly up with all your might Into that sky that resembles you I'm looking at you, colored by the dawn sky
