Happy happy happy Naru, going to become happy Naru~
If it gets me curious, oh I see! My dream will become real.

I have a maiden's heart. It's boring if it's just plain.
Pile on the sparkled and excitement, and decorate, deco!
If you try holding hands with the friend next to you,
Then you'll be connected to the friend next to them, too

I'll reach even the rainbow I can see faraway right away, definitely.

Happy happy happy Naru, going to become happy Naru~
If it gets me curious, oh I see! My dream will become fun.
I'll walk along the rainbow path
How interesting! It overflows! Look, this is the 7-colored various-colored dream!

Romance, studies, friendship, family.
They're all precious, important treasures, but... Huh?
I was able to smile when I had no likes or dislikes,
But what was it that was my most favorite thing??

I have to go... And search for the lost me right away!

Happy happy happy Naru, going to become happy Naru~
If it gets me curious, oh I see! Things will become mysterious
A-B-C-D-E, Naru Naru, I'll get into it.
I want to find my speeding heart. This is a colorful-ful colorful dream!
