Planet survival opening

kono sora ga kono kaze ga kono iro ga
moshi kiete shimattara
bokura wa bokura wa dou natte shimau n darou

kono umi ga kono hoshi ga kono yume ga kono toki ga
togirete shimawanu you ni

tabidachi da nayanderu hima nado nai
mugen ni higaru mirai ni mukatte
kakedashita ano hi hadashi no manma de
shinjite itai kawaranai ai-tachi wo

ano hikari ano namida ano egao ano uta mo
togirete shimawanu you ni

atarashii PE-JI wo mekutte mireba
mugen ni tsuzuita bokura no monogatari
kanashimi ya sayonara mo dakishimete
shinjite itai kawaranai ai-tachi wo

kono sora ga kono kaze ga kono iro ga
moshi kiete shimattara
bokura wa bokura wa dou natte shimau n darou

iza yukou nayanderu hima nado nai
mugen ni kagayaku ashita wo mezashite
wasurenai mune no tokimeki subete
shinjite itai kawaranai ai-tachi wo
