Yuku saki mo kimezu ni, aruki tsuzuke tayone
Kitai to fuan ni mune o, fukure masete
Hajimete miru machi ya, nandomo mita sora ga
Nandaka, ookiku, yake ni mabushi katta
Yume wa kitto tsukamu, yakusoku dake kawashi
Soshite bokurawa, ima, mirai no DOA o tataku
Atarashii kisetsu na, hajimarou to shite iru
Kagayaku taiyou no naka ni
Kawaranai egao to nuku mori ga arukara
Nori koerareru kitto futari, donna toki mo

Hontou wa itsudemo, hagayuku omounda
Omotta toori ni, naze ka ikanakute
Miageta aozora wa, kyou mo hateshinakute
Namida ga omowazu, afuresou ni naru yo
Motto tsuyoku nareru, kitto nani ga dekiru
Nayamu koto wa tabun, mienai yuuki ni naru
Atarashii kisetsu na, hajimarou to shite iru
Sousa omou mama de iisa
Futari no yume wa yagate, sorezore no mirai de
Kagayaki tsuzukeru, kanae rareru, shinji tsuzukete

Atarashii kisetsu na, hajimarou to shite iru
Kagayaku taiyou no naka ni
Futari no yume wa yagate, sorezore no mirai de
Kagayaki tsuzukeru, kanae rareru, shinji tsuzukete
