Japanesse
Ribon wo musunde waratte mitara kawatta watashi ni nareta ki ga shita
Chiisana yuuki ga jishin ni naru anata ni au made wasureteta
Onna no ko wa minna muteki ni nareru
Tokubetsu na mahou shitteru no
It's show time!
Dokidoki sasete ne itsudemo tokimekitai no
Ironna watashi misete ageru dakara
Motto motto sunao ni afureru kono kimochi wo
Anata ni todoketai yo
Uke totte ne my sweet heart
Hikari no hanataba dakishimetara mabushii ashita ni kitto naru kara
Ookina risou ni todoku you ni kokoro no tsubasa wo habatakase
Onnanoko wa minna kirei ni naru no
Taisetsu na hito ni deattara
It's show time!
Ukiuki suru you na hajimari kitai shite iru
Shiranai anata sagashitai yo motto
Zutto zutto chikaku de issho ni yume wo mitai ne
Te to te wo tsunaida nara
Fushigi da yo ne change my mind
It's show time!
Dokidoki sasete ne itsudemo tokimekitai no
Ironna watashi misete ageru dakara
Motto motto sunao ni afureru kono kimochi wo
Anata ni todoketai yo
Uketotte ne my sweet heart


English
When I tied the ribbon and smiled, I felt like I’d become a new person
That little courage became confidence, and I forgot about the time before I met you
Any girl can become invincible
We know a special magic
It's show time!

Give me the jitters, I want my heart to keep flutteriny
I’ll show you all kinds of sides of me
This feeling is overwhelming me, more and more openly
I want to give it to me
Take it, my sweet heart

If I embrace this bunch of flowers of light, it’s sure to become a bright tomorrow I’ll flap the wings of my heart to reach my huge ideal
Any girl will become beautiful
When she meets that special person
It's show time!

I’m holding out for a cheerful beginning
I want to keep searching for the you I don’t yet know
I want to stay close to you, dreaming together
When we’re holding hands
It’s so strange, change my mind
It's show time!

Give me the jitters, I want my heart to keep flutteriny
I’ll show you all kinds of sides of me
This feeling is overwhelming me, more and more openly
I want to give it to me
Take it, my sweet heart
