Tekst piosenki 'Birthday' wykonawcy Straightener

shirabakurete mimi o fusaide
mayonaka no arashi ga sugiru no o matsu nda
3-byō ni ichido inabikariru sora
sutorobo o rensha shita yō ni jikan ga tomatta
tōku made miwatasou to shite sukurappu no yama ni yojinobotta
shikaiwosaegiru ame o hajiku te wa itsunomanika yogorete ita

tashikame au kotoba de
kizutsuke au chikara de
itsuka deai wakarete
mukashikara bokura wa zutto
wakatteta yo

shiraga ga fuete namida moroku natte
kinou tsuita uso nante sugu ni wasureru nda
4-nen ni ichido mukaeru bāsu dē o
kimi to sugoshitai yo kirameku sekai o
kieru made mitodokeyou to shite jimen no tsudzuku kagiri oikaketa
kurai nyūsu kara somukeru me wa itsunomanika nigotte shimatta

tashikame au kokoro de
kizutsuke au teashi de
koe wa kabe o tsukinukete
hate shirazu bokura wa zutto
wakatteru yo
now or never!
