Natsu e no tobira akeyou
Dareka ga kitto
Matteru sa

Bokura wa mata koko ni tatteru
Hikari afureteru kono machikado ni

Doko e ikou? Doko demo ii sa
Kaze no muku mama ni ki no muku mama ni

Natsu e no tobira akeyou
Dareka ga soko de kitto
Matteru sa

Hesomagari mo yasashii yatsu mo
Sabishii dareka mo tsurete yuku no sa

Deau tame ni bokura wa umare
Kono sekai no ue hashirimawaru yo

Natsu e no tobira akeyou
Bokura no monogatari

Natsu e no tobira akeyou
Dareka ga soko de kitto

Ano kado wo magattara
Soko ni iru kimi ni au
Kake yotte waraiatte
Koe agete hashiridasou

Natsu e no tobira akeyou
Bokura no monogatari
Hajimeyou

Natsu e no tobira akeyou
Dareka ga soko de kitto
Matteru sa

Natsu e no tobira akeyou
Bokura no monogatari
Hajimeyou

Natsu e no tobira akeyou
Dareka ga soko de kitto
Matteru sa
