Promise by Hatsune Miku and Kagamine Rin (Lyrics)

[Rin]
Kizuguchi ni fureta sono toki
kimi wa kasuka ni furueteita
yukusaki ga kawarazu ni
tooi sora wo miteita

[Miku]
mune ni nadoru kono itami no
kotae ga hoshii wake janakute
tada kimi ga iru kagiri
yakusoku wo hatasu dake

[Rin/Miku]
namida no ato ga kieru made
hakanai kagayaki ga
[Miku]taeru koto nai youni
[Rin]tsuyoku dakishimeteru yo

[Rin/Miku]
yuraginai omoi wa sou
kimi to futari de tsumugu ashita e

sono hikari saegiru mono
furi harau kara
koware iku sekai ga ima
kodou no imi wo shimeshi hajimeta
kokoro no naka kataku chikau
kimi wo mamoru yo zutto...

[Rin/Miku]
yuraginai omoi wa sou
kimi to futari de tsumugu ashita e
sono hikari saegiru mono
furi harau kara
koware iku sekai ga ima
kodou no imi wa shimeshi hajimeta
kokoro no naka kataku chikau
kimi wo mamoru yo zutto...
