Lyrics
Kyou ga saikou no hi datte
Kokoro ni niji ga kakatte
Taiyou wo dakishimete
Subete wa kimi no mune ni
Ima da! tte nami ni tobinotte
Kaze ni fukare kimi to utaou
Kimi ga souzou dekiru
HAPPII de suteki na mirai
Sotto omoi egaite mite
Sore ga mieta no nara
Donna koto mo kanaeru
Chikara ga aru tte koto
Unmei ni karamete aa
Akirameyou to suru toki wa
Nani yori daiji na mono igai wa
Tebanashite mite mo ii
Kyou ga saikou no hi datte
Kokoro ni niji ga kakatte
Taiyou wo dakishimete
Subete wa kimi no mune ni
Ima da! tte nami ni tobinotte
Kaze ni fukare kimi to utaou
Hi ga shizumu you ni aa
Nemuri ni ochiteku, kyou mo
Kitto mata aeru sono hi made
Aa shiawase de ite ne
Kyou ga saikou no hi datte
Kokoro ni niji ga kakatte
Taiyou wo dakishimete
Subete wa kimi no mune ni
Ima da! tte nami ni tobinotte
Kaze ni fukare kimi to utaou
