[sansa]

kokoro ni kagayaku kono yume wo
kimi ni todoketai
shirufu no mabu sora
>shirufu(?) no mau sora

odayaka na nami no oto ga
kanaderu etende bokura no tabi na hajimaru
>kanaderu eden de bokura no tabi ga hajimaru

kimi no egao mamoru tame
tatakai tsuzukeyou
arashi no ato sotto kakaru
niji no yori ashitama
>niji no youni ashita ga

kokoro no tobira ohira itai
>kokoro no tobira wo hirakitai

kakare tsunakute wo
>tatoe tsurakutemo

kokoro no kagi wo bokura wa
sagashi tsuzuketteku
>sagashi tsuzuketeku

yasashi samo namida mo zenbu
omoi wo komete okurou
shinki no moride yuramutsuki
>shinpi no mori　de yuragu tsuki

kanashi hitomitemi tsumaru
>kanashii hitomi teni mitsumeru

kimi no tame

I can meet such a great song because of you! thank you.
I correct your romaji lyrics.
I don't hear some parts of lyrics clearly though.
