Lyrics:

Wanna be the biggest dreamer
Zensokuryoku de mirai mo
ima mo kake nukero

Sou boku wa ki zuitan da
zutto shukudai wasureteta
Sore wa hitotsu no nazo nazo nazo
"Boku wa dare nan darou?"

SURAIDINGU shite surimuketa
hiza itakutatte ne
Sugu tachiagaranakya
CHANSU wa nigete yuku wakatteru sa

* Big and bigger, biggest dreamer!
Yume miru koto ga subete hajimari
sore ga kotae daro
Dare yori tooku e tonde miseru yo
subete no asu o tsuranuite

Chiheisen made tonde yuke
hane o moratta yuukitachi
Tsuyoku ookiku naru tame ni
boku mo hashiridasou

Kikoete ita yo
KAUNTO DAUN zutto mae kara
Junbi wa dekiteru sa
ima sugu hajimeyou ZERO ni kaware!

Big and bigger, biggest dreamer!
Shinjirarenakya
mabataki shiteru setsuna ni kieru yo
Kokoro no hyouteki sorasazu hashire
subete no asu o tsuranuite

repeat *

repeat *

Big and bigger, biggest dreamer!
Yume miru koto ga subete hajimari
sore ga kotae daro

Wanna be the biggest dreamer
Zensokuryoku de
mirai mo ima mo kake nukero
