Daijina nanika Wakatta ano Sunny Day!
Honto no yasashisa tanoshisa oboeteta hi

Days nani yori mo muchuu ni natteta
jikan nante dou datte Yokutte
tooi hibi ga natsukashii

Mou saikouchou ni tanoshikute kienai koe tsukinai hanashi itsumo hikatteta koro

Jishin mo tsuita shippai mo nandomo shita dajedo wasurenai atatakana ano koro

Daijina nanika miushinatta Rainy Day
kuyashisa modokashisa namida mo oboeta hi

Daijina koto oshiete moratta Shiny Day
sasaerareta soshite shinjiraretanda

My Way ima to iu jikan de sae
ki ga tsukeba kako ni natteru
"kanashisa" kanjiru nima mo naku

Sou nanika wo mezashite ikiteru dakara yume miru sono sugata wa atarashii kagaki wo eru

Kagami ni utsuru omoi wa issho! dakara keshite iro asenai atatakatta ano koro

Daijina nanika miushinatta Rainy Day
ichi hatte shirazu ni dareka wo kidzutsuketeta

Daijina dareka ga ita kara koso Shiny Day
satoriaeta itsumo tasukeraretanda

Daijina nanika ga wakatta ima Shinya Day
arifureta kotoba de wa arukedo "arigatou"

Daijina hito ga itekureta ano Shiny Day
kono kotoba wo deatta hitotachi subete ni

Daijina koto shiranakatta ano Rainy Day

Daijina nanika mitsukerareta Shiny Day!

Wasuretai Shiny Day
