Big heart ~mikuroman no teema~
Daichi miuraYuuki wa mune ni aru kara
Daichi wo kerinagara
Doko made mo yuku yo mikuroman
Nan no tame nan darou?
Bokura ga umaretekita no wa...
Kokoro no hitomi de kotae wo sagasou
Chiisana koto demo daijina imi nara arun da ne
Kowagattari sezu ni mayottari sezu ni
Itsumo "i can do" yume wa "you can do"
Heitou ni furi sosoide kuru
Aozora no youni miagereba
* tobidasou big my heart
Yuuki wa mune ni aru kara
Mirai wo kaeru no wa sou sa bokura nanda
Kagayaite big my soul
Tamashii ga odoru you ni ne
Daichi wo kerinagara
Doko made mo iku yo mikuroman
Tadashii koto dake sekaijuu afuretara ii
Egao ga taenai sore wa risou kai?
Dakedo "i can do" kitto "you can do"
Ato wa yaru ka yaranai ka da yo ne
Yume no houkaku e hashiru dake
Tobidasou big my heart
Chippokena basho kara sugu
Yuujou mo aijou mo
Konna ni atsui yo
Kagayaite big my soul
Jibun wo shinjite ii ne
Akiramenai tsuyosa
Sono mama ni ikiru mikuroman
