HEY! mirai
"saa, mirai ga hajimaru yo!"

yuumei ni naritai!
tsuyoku naritai!
yume wa itsumo [Ta/Ko] mugen no kanousei

koi wo shitai!
KISS ga shitai
mune wa itsumo [Og/Ni] takanaru shouraisei

hanaseba nagai kedo
kiite hoshii
gakkou ja osowarenai
keiken no ETOSETORA

(WAO!)
[Ii/Ab] HEY! kono machi wa
watashitachi wo sodatete kureta basho ne
(iroiro to)
HEY! kono saki wa
watashitachi ga tsukuru mirai!

chotto yasumanai?
kakko yokunai?
joshi atsumarya subete ga gimonkei

kotae wa hitotsu ja nai
jinsei wa
kekka ga subete ja nai ga
hajimenakya hajimannai

(WAO!)
[Ii/Ab] HEY! kono sora wa
