Lyric: Seishun Line (Big Wind Up)

kirakira hikaru seishun RAIN o bokura wa ima hashiridasu yo
tsunagu omoi o yume no saki made

natsu no GURAUNDO bokura wa mujaki ni hakusen o tobikoeteiku
taiyousae mo te ga todokisou de nanimo kowakunakatta

kimi to sora ni egaita yume wa ikutsu ni naru darou
senaka o tataitekureta sono te o tsuyoku nigitta

sou sa kirakira hikaru seishun RAIN o bokura wa ima hashiridasu yo mou modoranai
zutto DORAMATIKKU na kiseki o sa-ga-shi-te shinjiru mama te o nobasu yo
tsunagu omoi o yume no saki made

madobe no yuuhi o yubi de nazotte wa chiisana fuan o tsu-bu-shi-te-i-ta
furikiru you ni unazuita boku ni kimi wa waratte kureta

yubikiri shi-ta yakusoku o ima mo futari dakishimete
tashika ni oitsuzuketeku sono te o hanashi wa shinai

sou sa kirakira hikaru seishun RAIN o bokura wa ima yabutteiku mou mayowanai
zutto ROMANTIKKU na mirai o sa-ga-shi-te shinjiru mama te o nobasu yo
tsunagu omoi o yume no saki made

kirakira hikaru seishun RAIN o bokura wa ima koeteiku yo mou modorenai

sou sa kirakira hikaru seishun RAIN o bokura wa ima hashiridasu yo mou modoranai
zutto DORAMATIKKU na kiseki o sa-ga-shi-te shinjiru mama te o nobasu yo
tsunagu omoi o

sou sa kirakira hikaru seishun RAIN o bokura wa ima hashiridasu yo
tsunagu omoi o yume no saki made
