Mukashi nagara no SAIDAA no nemuru kokoro no tama
Toridashite motto hiroi hikari ni attete mireba
Shira nai iro mo oboete migakeba hikaru kokoro no tama
Nanda kanda de ofuro de shizundari ushinattari de
Kyou made ikite kita ganbari wa taikoban

*Marui marui BI-dama ni utsuru wa PIISU SAIN no atashi de
Itsuka mata nozoita toki mo kitto waratterun ja nai kana

Chotto BURUU ni ochita toki demo wasure nai de hitotsu dake
Donna ni tsurai mushi ni shihai saretetemo wasure nai de
Kakureteta hikari mo oboete mada mada ikeru kono saki
Chotto hirune no jikan wo koete uchuu made no yume tabi
Kidukeba awatete mata ganbareba ii.

Marui marui BI-dama ni utsuru wa yowamushi na atashi de
Jishin wa yuuki wa chanto aru no katsu irete mae wo muite aruku dake

Utsuru jibun wo nigezu ni mireba nigezu ni mireba mieru

*Repeat

Marui marui BI-dama ni utsuru wa PIISU SAIN no atashi de
Kawaii oba-chan ni natte mo
Kitto egao wo utsushidaseru you
Sou waratterun ja nai kana
