太陽が攻めて来ちゃう
紫外線と露出感のはざま
友達の様な顔しながら
AH　内心メラメラと勝負

恥ずかしいはずなのに
ワンピじゃダメなの
もういいかい?
まだダメだよ
もういいかい?
まだダメだよ
もういいかい?
もういいよ　かかって来なさい!

夏夏夏夏……夏Bikini
ドキドキドキ…胸Dokiri
若さじゃないのよ　勇気よ
ダイエットしてる間に夏が終わるよ
注目　注目　注目　注目　注目　注目
Chu chu chu chu chu chu　〜もくっ!

どんな時も目立とう精神
早起きして　メイクも丁寧
蝉達が目覚めるより早く
YEAH　夏を先取りしましょう

ポンポコ腹気になっても
大盛り食べちゃった
あのね?
なになになに
あのね?
なになになに
あのね?
さあ夏が始まったよ!

The sun starts to attack
in the middle of the ultraviolet rays and the feeling of exposure
While putting on a face pretending that I'm a friend
I fight my true intentions that flare up

Even though I'm supposed to feel embarrased
I don't want to wear an one-piece
Are you done yet?
No, not yet!
Are you done yet?
No, not yet!
Are you done yet?
I am now, come at me!

Summer summer summer summer... summer bikini
Thump thump thump... my heart beats hard
It's not about youthfulness, it's about courage
While I'm dieting, summer's gonna end
Be careful, careful, careful
careful, careful, careful
Ca-ca-ca-ca-ca-careful!

At any time, I try to stand out
Waking up early and putting on make-up carefully
Let's anticipate summer
even before the cicadas open their eyes

Even though I'm worried about my big stomach
I ate a large serving
Um...
Yes, what is it?
Um...
Yes, what is it?
Um...
Summer has begun!

Summer summer summer summer... summer bikini
Thump thump thump... my heart beats hard
It's not about youthfulness, it's about fighting spirit
This is the age where we want to be popular instead of searching for a boyfriend
Be careful, careful, careful
careful, careful, careful
Ca-ca-ca-ca-ca-careful!
